Look for subtle (yet telling) signs like ventricular hypertrophy, discordant EKG findings, bilateral carpal tunnel syndrome, and spontaneous biceps tendon rupture. Utilize the right diagnostic tests. Endomyocardial biopsy remains the gold standard, but non-invasive tools like PYP scan with SPECT imaging and genetic testing are essential for accurate diagnosis. Differentiating hereditary from wild-type ATTR is critical, as genetic forms may have a more aggressive course and familial implications. Early diagnosis and intervention significantly improve prognosis, making vigilance in screening and prompt treatment initiation essential. The future is now! Cutting-edge therapies are transforming the treatment landscape, including TTR stabilizers, gene silencers, and emerging technologies like CRISPR-Cas9 and antibody-based treatments. Notes – Biology of Transthyretin amyloid cardiomyopathy What is transthyretin amyloid (aTTR) and how is it derived? Transthyretin (TTR) is a transport protein primarily synthesized by the liver, responsible for carrying thyroid hormones (thyroxine) and retinol (vitamin A) in the blood. It circulates as a tetramer, composed of four identical monomers, which is essential for its stability and function. In transthyretin amyloid (ATTR) amyloidosis, the TTR protein becomes unstable, leading to its dissociation into monomers. These monomers misfold and aggregate into insoluble amyloid fibrils, which deposit extracellularly in tissues such as the heart, nerves, and gastrointestinal tract. This progressive amyloid deposition leads to organ dysfunction, including restrictive cardiomyopathy and neuropathy. There are two main forms of ATTR amyloidosis: hereditary (variant) and wild-type (senile) ATTR. Hereditary ATTR (ATTRv) is caused by mutations in the TTR gene. These mutations destabilize the TTR tetramer, making it more prone to dissociation. This increases misfolding and amyloid fibril formation, resulting in systemic amyloid deposition. Wild-type ATTR (ATTRwt) occurs without genetic mutations and is primarily age-related. Over time, even normal TTR tetramers can become unstable, leading to gradual misfolding and amyloid deposition, particularly in the heart. ATTRwt is a common but often underdiagnosed cause of heart failure with preserved ejection fraction (HFpEF) in elderly individuals. How does aTTR lead to deleterious effects in the heart and other organ systems? Transthyretin amyloidosis leads to organ dysfunction through the deposition of misfolded TTR protein as amyloid fibrils, which accumulate extracellularly and disrupt normal tissue architecture and function. These deposits cause progressive damage by increasing stiffness, inducing oxidative stress, and impairing normal cellular function. Cardiac manifestations include amyloid deposition in the myocardial interstitium, leading to increased stiffness, diastolic dysfunction, and restrictive cardiomyopathy. As the disease progresses, systolic dysfunction may develop. Amyloid infiltration can also cause arrhythmia, conduction abnormalities such as atrioventricular block and atrial fibrillation, valvular thickening, coronary ischemia, and pericardial effusion. Disruption of transverse tubules in cardiomyocytes contributes to heart failure and arrhythmia. Systemic involvement depends on the culprit amylodogenic protein. AL amyloidosis caused by deposition of immunoglobulin light chains may deposit in and disrupt the function of any tissue/organ except for the central nevous system. ATTR amyloidosis primarily affects the heart, peripheral nerves, and the musculoskeletal system. Peripheral neuropathy can cause sensory loss, pain, and motor weakness, while autonomic dysfunction may lead to orthostatic hypotension, gastroparesis, and urinary retention. Carpal tunnel syndrome is a common early sign. Gastrointestinal amyloid deposits (specifically for AL but not ATTR) can cause gastroparesis, diarrhea, constipation, and malabsorption, leading to weight loss and malnutrition. Renal involvement (specifically for AL but not ATTR), though less common, can present as proteinuria and renal dysfunction. Amyloid deposition in soft tissues and the lungs may lead to hoarseness and musculoskeletal stiffness. As the disease progresses, continued amyloid accumulation leads to worsening organ dysfunction and failure. Early diagnosis and intervention are essential to slowing disease progression and managing symptoms effectively. When and why is aTTR cardiac amyloidosis hereditary versus obtained sporadically? Hereditary aTTR is caused by genetic mutations in the TTR gene, which are often autosomal dominant. Common mutations include V122I (more common in African Americans) and V30M (more common in certain regions like Portugal). Hereditary aTTR typically presents at an earlier age and may have a more aggressive course, with a higher likelihood of neuropathic involvement. Wild-type aTTR, or senile systemic amyloidosis, occurs sporadically and is more common in older individuals, typically without a family history. The exact reasons for the development of wild-type aTTR are not fully understood, but factors like chronic inflammation and exercise may play a role in the misfolding and aggregation of the normal TTR protein.

Join CardioNerds EP Council Chair Dr. Naima Maqsood and Episode Lead Dr. Jeanne De Lavallaz as they discuss the results of the ARREST-AF Trial with expert faculty Dr. Prashanthan Sanders and Dr. Mehak Dhande. Audio editing by CardioNerds intern Bhavya Shah. The ARREST-AF trial enrolled 122 patients with a BMI of 27 kg/m 2 or greater and at least one cardiovascular risk factor with either paroxysmal or persistent AF and were scheduled to undergo de novo AF ablation. They were randomized to an intensive risk factor management (RFM) program versus usual care. The RFM program addressed obesity, sleep apnea, HTN, HLD, tobacco, and alcohol abuse, whereas the usual care arm had a discussion of risk factors but without an extensive risk factor modification or follow-up program. The study population had a mean age of 60 years, a mean BMI of 33 kg/m 2 , and 56-60% of patients with persistent AF. A third of the study population was female. The trial showed a significant improvement in the primary endpoint of the percentage of patients free from atrial fibrillation after ablation in those receiving the intensive lifestyle RFM program. At the end of the 12.3-month follow-up period, 66% percent of patients in the RFM group were free from AF compared to 42% in the usual care group (HR 0.53, p = 0.03). The RFM group also showed significant improvement in AF symptom severity, decline in body weight, systolic blood pressure, glycemic control, and exercise capacity. On average, patients in the RFM arm lost 9 kg of weight compared to 1 kg in the control group. Similarly, systolic blood pressure decreased by 13.1 mmHg in the RFM group but increased by four mmHg in the control group.

CardioNerds (Dr. Dan Ambinder and guest host, Dr. Pooja Prasad) join Dr. Donny Mattia from Phoenix Children’s pediatric cardiology fellowship, Dr. Sri Nayak from the Mayo Clinic – Arizona adult cardiology fellowship, and Dr. Harrison VanDolah from the University of Arizona College of Medicine – Phoenix Med/Peds program for a sunrise hike of Piestewa Peak, followed by some coffee at Berdena’s in Old Town Scottsdale (before the bachelorette parties arrive), then finally a stroll through the Phoenix Desert Botanical Gardens to discuss a thought-provoking case series full of clinical cardiology pearls. Expert commentary is provided by Dr. Tabitha Moe. Episode audio was edited by Dan Ambinder. They discuss the following case: Cardiology is consulted by the OB team for a 27-year-old female G1, now P1, who has just delivered a healthy baby boy at 34 weeks gestation after going into premature labor. She is experiencing shortness of breath and is found to have a significant past cardiac history, including atrial fibrillation and preexcitation, now with a pacemaker and intracardiac defibrillator. We review the differential diagnosis for peripartum cardiomyopathy (PPCM) and then combine findings from her infant son, who is seen by our pediatric cardiology colleagues and is found to have severe hypertrophic cardiomyopathy (HCM). Genetic testing for both ultimately reveals a LAMP2 mutation consistent with Danon Disease. The case discussion focuses on the differential diagnosis for PPCM, HCM, pearls on Danon Disease and other HCM “phenocopies,” and the importance of good history. “To study the phenomena of disease without books is to sail an uncharted sea, while to study books without patients is not to go to sea at all.” – Sir William Osler.

Check out CardioNerds SWAG! Become a CardioNerds Patron! Case Media Pearls Peripartum cardiomyopathy is a diagnosis of exclusion – we must exclude other possible etiologies of heart failure! Be on the lookout for features of non-sarcomeric HCM – as Dr. Michelle Kittleson said in Episode 166 , “LVH plus” states. HCM with preexcitation, heart block, strong family history, or extracardiac symptoms such as peripheral neuropathy, myopathy, or cognitive impairment should be evaluated for infiltrative/inherited cardiomyopathies! As an X-linked dominant disorder, Danon disease will present differently in males vs females, with males having much more severe and earlier onset disease with extracardiac features. Making the diagnosis for genetic disorders such as Danon disease is important for getting the rest of family members tested as well as the opportunity for specialized treatments such as gene therapy Up to 5% of Danon disease cases may be due to copy number variants, which may be missed in genetic testing that does not do targeted deletion/duplication analysis!). Notes What is the differential diagnosis for peripartum cardiomyopathy? Peripartum cardiomyopathy is a diagnosis of exclusion – we must exclude other possible etiologies of heart failure! First, ensure that you are not missing an acute life-threatening etiology of acute decompensated heart failure – pulmonary embolism, amniotic fluid embolism, ACS, and SCAD should all be ruled out. Second, a careful history can identify underlying heart disease or risk factors for the development of heart failure, such as substance use, high-risk behaviors that put one at risk for HIV infection, and family history that suggests an inheritable cardiomyopathy. Lastly, a careful review of echocardiographic imaging may also identify underlying etiologies that warrant a change in management. Diagnosis of peripartum cardiomyopathy is important to consider as within 7 days of onset, patients may be eligible for treatment with bromocriptine – consider referring the patient for enrollment in the ongoing RCT ReBIRTH. Check out Cardionerds Episode 113 and the great article linked below for more details on heart failure in pregnancy and postpartum! What is the differential diagnosis for hypertrophic cardiomyopathy? Though by far the most common differential diagnosis for HCM is simple LVH or athlete’s heart, as Dr. Michelle Kittleson taught us in CardioNerds Episode 166, we should “remain alert for “LVH+” states.” It is helpful to think of them in two buckets – sarcomeric mutations (classic HCM) or non-sarcomeric causes (“phenocopies”). If you see systemic signs like peripheral neuropathy, renal dysfunction, or skin changes – clues towards a systemic pathology (for adult colleagues, first think amyloidosis; for peds, colleagues, think genetic syndromes such as RASopathies like Noonan syndrome, glycogen, and lysosomal storage diseases like Fabry). Additionally, certain additional cardiac findings can point towards a non-sarcomeric HCM – recall way back in CardioNerds Episode 68 when our friends at VCU presented a man in his 60s with a history of WPW/preexcitation and HCM and was found to have a PRKAG2 mutation, which is a similar lysosomal vacuolopathy to Danon disease. Another example was seen in Episode 349 when we saw a patient with HCM and heart block who was found to have Fabry disease. What is Danon disease, and how does it present? Danon disease is a rare X-linked dominant genetic disorder due to deficiency in LAMP2 , a glycoprotein involved in protecting the lysosome from its roles in endocytosis and autophagy When deficiency of LAMP2 occurs, products build up into vacuoles and lead to cardiomyocyte dysfunction and death. Interestingly, autophagy disruption is the suspected mechanism of cardiomyopathies from anthracyclines and hydroxychloroquine – Danon disease severity underscores the importance of this process! Estimated prevalence of Danon disease in adult patients with HCM is 1-4%, however when both HCM and pre-excitation are present, this rises to 17%. It is highly penetrant, meaning most patients with the mutation will show symptoms. There are several extracardiac features such as skeletal myopathy, retinopathy, and cognitive impairment – these correlated with areas in the body where LAMP2 is expressed more! Classic presentations – remember that X-linked inheritance results in differential expression between males and females! Males: young onset with severe LVH/HCM and extracardiac phenotype Females: isolated cardiomyopathy (can be either dilated or hypertrophic) with preexcitation arrhythmias with a family history suggesting X-linked dominant transmission (i.e., males more severely affected than females). When taking a family history, note that male-to-male transmission (can’t happen since males don’t pass on an X chromosome to their male children) or female-to-offspring transmission (suggests mitochondrial disease) should prompt alternate diagnosis. However, an estimated 1/3 of Danon disease cases are de novo mutations! See Episode 300 for a great in-depth overview of the pathophysiology of Danon disease How is Danon disease diagnosed? Though there are some proposed characteristic cardiac MRI findings (diffuse LGE sparing the interventricular septum), diagnosis is genetic with a loss-of-function mutation in LAMP2 paired with characteristic cardiac or extracardiac features (see below diagnostic algorithm from Hong et al. JACC 2023) LAMP2 is now included in most hypertrophic and dilated CM panels – if found, it is crucial to ensure the patient’s family members also undergo testing and potentially cardiac evaluation! (Note: up to 5% of Danon disease cases may be due to copy number variants, which may be missed in genetic testing that does not do targeted deletion/duplication analysis!) Differential Diagnosis Sarcomeric HCM – the “classic” HCM, which has numerous genetic causes, all of which affect the sarcomere with age-related penetrance leading to three peaks in age at onset (infancy <1yr, teenage/early adulthood, and mid-adulthood). Progression towards massive LVH and systolic dysfunction is uncommon (<10%) and should raise suspicion of a rare genocopy such as Danon. EKG is usually mostly normal in these patients, unlike in Danon disease, which often has striking abnormalities. Pompe disease – lysosome storage disease from mutations in acid alpha-glucosidase leading to lysosomal glycogen accumulation. Autosomal recessive. It can be an infantile form with severe LVH/HCM, and the later forms can have classic skeletal myopathy as well, but usually, these patients have less severe cardiac features. RAS-opathies – genetic diseases due to mutations in the RAS/MAPkinase pathway. Classic examples are Noonan syndrome, LEOPARD syndrome, and Costello syndrome. All have classic extracardiac manifestations as well as oftentimes HCM, as well as congenital heart disease such as pulmonary valve stenosis. Fabry disease – also an X-linked recessive lysosomal disorder due to alpha-galactosidase A enzyme deficiency; however, it is rarely prominent in childhood and is usually more characterized by extracardiac manifestations. HCM is a cardiac manifestation presenting in the 30s-40s. Friedrich ataxia – autosomal recessive multisystem disease due to GAA sequence expansion in the FXN gene that encodes frataxin, a mitochondrial protein, which impairs mitochondrial oxidative phosphorylation. “HCM” is a common disease manifestation in addition to the classic severe neurologic presentation. Mitochondrial diseases – heterogenous conditions affecting mitochondrial DNA, transmitted in matrilinear pattern, with cardiac hypertrophy being a classic disease manifestation in addition to preexcitation. These may present with severe cognitive impairment than Danon disease. PRKAG2 mutations – cause dysregulation of adenosine monophosphate kinase, culminating in accumulation of vacuoles within glycogen stores. Early-onset cardiac hypertrophy with preexcitation can be similar to Danon disease. There are no extracardiac features and the inheritance pattern is autosomal dominant. For a great summary, see Table 2 in Hong K et al. International Consensus on Differential Diagnosis and Management of Patients with Danon disease: JACC state-of-the-art Review. JACC 2023 Oct, 82 (16) 1628-1647 . For patients who undergo heart transplantation for a genetic/inherited cause, it is crucial to recall their index diagnosis after transplant – they may have extracardiac disease manifestations!

CardioNerds ( Dr. Dan Ambinder and Dr. Yoav Karpenshif – Chair of the CardioNerds Critical Care Cardiology Council) join Dr. Munim Khan, Dr. Shravani Gangidi, and Dr. Rachel Goodman from Tufts Medical Center’s general cardiology fellowship program for hot pot in China Town in Boston. They discuss a case involving a patient who presented with stress cardiomyopathy leading to cardiogenic shock. Expert commentary is provided by Dr. Michael Faulx from the Cleveland Clinic. Notes were drafted by Dr. Rachel Goodman. Audio editing by Dr. Diane Masket . A young woman presents with de novo heart-failure cardiogenic shock requiring temporary mechanical circulatory support who is found to have basal variant takotsubo cardiomyopathy. We review the definition and natural history of takotsubo cardiomyopathy, discuss initial evaluation and echocardiographic findings, and review theories regarding pathophysiology of the clinical syndrome. We also highlight complications of takotsubo cardiomyopathy, with a focus on left ventricular outflow obstruction, cardiogenic shock, and arrythmias. “To study the phenomena of disease without books is to sail an uncharted sea, while to study books without patients is not to go to sea at all.” – Sir William Osler. CardioNerds thank the patients and their loved ones whose stories teach us the Art of Medicine and support our Mission to Democratize Cardiovascular Medicine.

Pearls Takotsubo cardiomyopathy is defined as a reversible systolic dysfunction with wall motion abnormalities that do not follow a coronary vascular distribution. Takotsubo cardiomyopathy is a diagnosis of exclusion; patients often undergo coronary angiography to rule out epicardial coronary artery disease given an overlap in presentation and symptoms with acute myocardial infarction. There are multiple echocardiographic variants of takotsubo. Apical ballooning is the classic finding, but mid-ventricular, basal, and biventricular variants exist as well. Patients with takotsubo cardiomyopathy generally recover, but there are important complications to be aware of. These include arrhythmia, left ventricular outflow tract (LVOT) obstruction related to a hyperdynamic base in the context of apical ballooning, and cardiogenic shock. Patients with Impella devices are at risk of clot formation and stroke. Assessing the motor current can be a clue to what is happening at the level of the motor or screw. Notes What is Takotsubo Syndrome (TTS)? TTS is a syndrome characterized by acute heart failure without epicardial CAD with regional wall motion abnormalities seen on echocardiography that do not correspond to a coronary artery territory (see below). 1 TTS classically develops following an acute stressor—this can be an emotional or physical stressor. 1 An important feature of TTS is that the systolic dysfunction is reversible. The time frame of reversibility is variable, though generally hours to weeks. 2 Epidemiologically, TTS has a predilection for post-menopausal women, however anyone can develop this syndrome. 1 TTS is a diagnosis of exclusion. Coronary artery disease (acute coronary syndrome, spontaneous coronary artery dissection, coronary embolus, etc) should be excluded when considering TTS. Myocarditis is on the differential diagnosis. What are the echocardiographic findings of takotsubo cardiomyopathy? The classic echocardiographic findings of TTS is “apical ballooning,” which is a way of descripting basal hyperkinesis with mid- and apical hypokinesis, akinesis, or dyskinesis. 3 There are multiple variants of TTS. The four most common are listed below: 3 (1) Apical ballooning (classic TTS) (2) Mid-ventricular variant (3) Basal variant (4) Focal variant Less common variants include the biventricular variant and the isolated right ventricular variant. 3 Do patients with TTS generally have EKG changes or biomarker elevation? Patients often have elevated troponin, though the severity wall motion abnormalities seen on TTE is generally out of proportion to the degree of troponin elevation. 4 BNP/NTproBNP are typically elevated, especially early in the course. 4 During the acute phase (defined as within the first 12 hours), patients may have ST elevation or depression, T wave inversions, new LBBB, or QT prolongation. 4 What are complications of takotsubo cardiomyopathy? Heart failure 2 LV outflow tract obstruction—if there is an LVOT obstruction, it is important to avoid diuretics, vasodilators such as nitroglycerin, and inotropic agents. 2 Cardiogenic shock. 2 Atrial and ventricular arrhythmias. 2 LV thrombus—this is of particular risk in patients with the classic “apical ballooning” variant of takotsubo due to apical akinesis and therefore stagnant flow. 2 References Lyon AR, Citro R, Schneider B, et al.

Pearls – Treating Inflammation Our understanding of the pathophysiology of atherosclerosis has undergone a few iterations from the incrustation hypothesis to the lipid hypothesis to the response-to-injury hypothesis and culminating with our current understanding of the inflammation hypothesis. Both the adaptive and innate immune systems play instrumental roles in the pathogenesis of atherosclerosis. After adequately controlling classic modifiable risk factors such as blood pressure, dyslipidemia, glucose intolerance, and obesity, systemic inflammation as assessed by CRP can be ascertained as CRP is associated with ~1.8-fold increased risk of cardiovascular events Although the most common side effect of colchicine is gastrointestinal intolerance, colchicine can induce lactose intolerance, so a lactose free diet may help ameliorate colchicine-induced GI symptoms. Anti-inflammatory therapeutics have shown promise in reducing cardiovascular risk but much more is to be learned with ongoing and future basic, translational, and clinical research. Show notes – Treating Inflammation What are the origins of the inflammatory hypothesis? The first hypothesis as to the pathogenesis of atherosclerosis was the incrustation hypothesis by Carl Von Rokitansky in 1852. He suggested that atherosclerosis begins in the intima with thrombus deposition.In 1856, Rudolf Virchow suggested the lipid hypothesis whereby high levels of cholesterol in the blood lead to atherosclerosis. He observed inflammatory changes in the arterial walls associated with atherosclerotic plaque growth, called endo-arteritis chronica deformans.In 1977, Russell Ross suggested the response-to-injury hypothesis, that atherosclerosis develops from injury to the arterial wall.In the 1990’s the role of inflammation in ASCVD became more recognized. Both the adaptive and innate immune system are critical in atherosclerosis. Lipids and inflammation are synergistic in that lipid exposure is required but they translocate through damaged endothelium which occurs by way of inflammatory cytokines, namely within the NLRP3 inflammasome (IL-1, IL-6 etc.).Smooth muscle cells are also involved. They migrate to the endothelial region and secrete collagen to create the fibrous cap. They can also transform into macrophage-like cells to take up lipids and become foam cells. T, B, and K cells are also part of this milieu. In fact, neutrophils, macrophages and monocytes make up only a small portion of the cells involved in the atherosclerotic process. What are ways to individually optimize one’s ASCVD risk? Ensure the patient is on appropriate antiplatelet therapy, lipid lowering therapy, blood pressure is well controlled, and the Hemoglobin A1c is well controlled. Smoking cessation is pivotal. If the patient has an elevated Lipoprotein (a), pursue more aggressive lipid lowering therapy. Targeted therapies may become available in the future. Assess the patient’s systemic inflammatory risk as measured by C-Reactive Protein (CRP) What is the evidence for util izing CRP in risk stratification? CRP, initially termed Fraction C (discovered as a c polysaccharide component of the pneumococcal cell wall), was first discovered at Rockefeller University in the 1930’s. It was discovered to be an acute phase reactant in the 1940’s and noted to be synthesized in the liver in the 1960’s. Although it is not causal in atherosclerosis, elevated CRP is associated with elevated rates of cardiovascular disease. This was first noted in the landmark New England Journal of Medicine study by Ridker et al that showed elevated CRP was associated with elevated cardiovascular risk and treating with anti-inflammatory medication (aspirin) lowered CRP and CV risk. The statin trials also showed reduction in CRP levels was associated with better outcomes. High-sensitivity CRP (hsCRP) >3 mg/L has odds ratio of ~1.8 for risk of CV disease. Recent analyses of the PROMINENT, REDUCE-IT, and STRENGTH trials demonstrated that hsCRP was a more powerful determinant of recurrent CV events, CV death, and all-cause mortality than LDL-C. After effectively controlling the previously stated modifiable risk factors, what therapeutic options remain in a patient with an elevated CRP? CANTOS trial was the first proof of concept trial investigating Canakinumab (an IL-1 inhibitor) which showed a ~15% relative risk reduction in cardiovascular events CIRT trial investigated methotrexate in patients without autoimmune disease. It was stopped early due to it being a negative trial. This emphasized the complex role inflammation plays in ASCVD, and that both patient selection and chosen anti-inflammatory therapy are important to consider for ASCVD risk reduction. Colchicine has seen a lot of focus in this space with trials such as COLCOT, COPS, LODOCO, LODOCO 2, LODOCO MI. Overall, it appears that colchicine may be more effective in chronic stable ischemic heart disease. The CLEAR SYNERGY trial investigated colchicine in the peri-MI period and was a negative trial. However, we do not yet have the published data to further analyze it. A review article by Potere et al (referenced below) provides a useful summary of novel therapies and upcoming trials in the inflammation in ASCVD space. How do we approach inflammation in women? We know that immune response differs between men and women. Women have more robust immune response to vaccines and viruses and greater innate and adaptive immune responses. Women have slightly higher CRP than men. Studies have shown that average high sensitivity hsCRP is 1.7 for women and 1.2 for men. In the JUPITER trial, the subgroup of patients with hsCRP>7 mg/L had the highest proportion of women relative to men. Regardless, hsCRP remains a reliable predictor of CV events in both men and women. What are some practical considerations when starting colchicine? It may help with adherence, if you walk patients through what to expect with the medication. Obtain renal and liver function tests as both organs contribute to colchicine metabolism and clearance. Obtain a thorough medication reconciliation as colchicine has some notable drug-drug interactions. The most common side effects is GI intolerance; cytopenias are rare occurrences. Note that colchicine can induce lactose intolerance, a potential mechanism for causing GI intolerance, so a lactose free diet may help with adherence. What do we have to look forward to in the anti-inflammation space in CV disease? There is still a lot to be learned and discovered in this space. Some clinical trials to look out for are the ZEUS , ARTEMIS , and HERMES trials which look at Ziltivekimab, an IL-6 inhibitor, in chronic kidney disease, acute myocardial infarction, and heart failure, respectively.

Pearls - Targeting Inflammation for Cardiovascular Risk "If you don’t measure it, you can’t treat it”: Incorporate hs-CRP into routine practice for patients at risk of cardiovascular events, as it provides crucial information for risk stratification and management. Recognize the dual benefits of statins in lowering both LDL and inflammation, particularly in patients with elevated hs-CRP. Encourage patients to adopt heart-healthy habits, as lifestyle changes remain foundational in reducing both cholesterol and inflammatory risk. Reminder that most autoimmune or inflammatory diseases, from psoriasis to Addison’s disease to lupus to scleroderma to inflammatory bowel disease, have been shown to have elevated cardiovascular risk Ongoing randomized trials including ZEUS, HERMES, and ARTEMIS will inform whether novel targeting of IL-6 can safely lower cardiovascular event rates or slow renal progression Show notes - Targeting Inflammation for Cardiovascular Risk Why is it important to measure both LDL and hs-CRP, and what factors increase hs-CRP? Inflammation and hyperlipidemia are synergistic in promoting atherosclerosis. They interact to exacerbate plaque formation and instability, increasing the risk of cardiovascular events. Just like we measure blood pressure and LDL to know what to treat, we should measure hs-CRP to guide targeted therapy. Clinical Example: in Ms. Flame's case, despite achieving target LDL levels with statins, her elevated hs-CRP indicates ongoing inflammation and residual cardiovascular risk that should be assessed. Residual inflammatory risk should be assessed in both primary and secondary prevention. Increased BMI1, smoking2, a sedentary lifestyle3, and genetics4 (such as a higher risk of metabolic disease in South Asians) all raise hs-CRP levels. SGLTi5 and GLP-1 agonists6 have also been shown to decrease hs-CRP levels. What data do we have to support measuring hs-CRP? Women’s Health Study7: an early study showing that hs-CRP predicted risk at least as well as LDL cholesterol and that models incorporating hs-CRP in addition to lipids were significantly better at predicting risk than models based on lipids alone. JUPITER Trial8 (Primary Prevention): Among patients with normal LDL but elevated hs-CRP there was a 44% reduction in major cardiovascular events (>50% in MI and stroke) and a 20% reduction in all-cause mortality in patients treated with statins. These results led to changes in guidelines in recognizing the need to measure and treat inflammation. CANTOS Trial9 (Secondary Prevention): Randomized >10K patients with previous MI and hs-CRP ≥ 2mg/L and found that canakinumab reduced hs-CRP level from baseline in a dose-dependent manner, without reduction in the LDL, ApoB, TG, or blood pressure. What are the guidelines and supportive data on using Colchicine?…

Question #37 Mr. S is an 80-year-old man with a history of hypertension, type II diabetes mellitus, and hypothyroidism who had an anterior myocardial infarction (MI) treated with a drug-eluting stent to the left anterior descending artery (LAD) 45 days ago. His course was complicated by a new LVEF reduction to 30%, and left bundle branch block (LBBB) with QRS duration of 152 ms in normal sinus rhythm. He reports he is feeling well and is able to enjoy gardening without symptoms, though he experiences dyspnea while walking to his bedroom on the second floor of his house. Repeat TTE shows persistent LVEF of 30% despite initiation of goal-directed medical therapy (GDMT). What is the best next step in his management?AMonitor for LVEF improvement for a total of 60 days prior to further interventionBImplantation of a dual-chamber ICDCImplantation of a CRT-DDContinue current management as device implantation is contraindicated given his advanced age Answer #37 Explanation Choice C is correct. Implantation of a CRT-D is the best next step. In patients with nonischemic DCM or ischemic heart disease at least 40 days post-MI with LVEF ≤35% and NYHA class II or III symptoms on chronic GDMT, who have reasonable expectation of meaningful survival for >1 year,ICD therapy is recommended for primary prevention of SCD to reduce total mortality (Class 1, LOE A). A transvenous ICD provides high economic value in this setting, particularly when a patient’s risk of death from ventricular arrhythmia is deemed high and the risk of nonarrhythmic death is deemed low. In addition, for patients who have LVEF ≤35%, sinus rhythm, left bundle branch block (LBBB) with a QRS duration ≥150 ms, and NYHA class II, III, orambulatory IV symptoms on GDMT, cardiac resynchronization therapy (CRT) is indicated to reduce total mortality, reduce hospitalizations, and improve symptoms and QOL. Cardiac resynchronization provides high economic value in this setting. Mr.…

In this episode, Dr. Gurleen Kaur (Cardiology FIT at Brigham and Women’s Hospital and APD of the CardioNerds Academy) and Dr. Diane Masket (Medicine Resident at the University of Chicago Northshore and CardioNerds Academy Intern) discuss with Dr. Minnow Walsh (Medical Director of the Heart Failure and Cardiovascular programs at Ascension St. Vincent Heart Center in Indianapolis) about her personal and professional journey in Cardiology. They discuss Dr. Walsh’s authorship of the recent ACC statement on career flexibility in Cardiology, her involvement with the ACC at both the local and national levels, and her passion for making cardiology a more inclusive and welcoming field for all. Notes were drafted by Dr. Diane Masket and episode audio was engineered by student Dr. Grace Qiu. The PA-ACC & CardioNerds Narratives in Cardiology is a multimedia educational series jointly developed by the Pennsylvania Chapter ACC, the ACC Fellows in Training Section, and the CardioNerds Platform with the goal to promote diversity, equity, and inclusion in cardiology. In this series, we host inspiring faculty and fellows from various ACC chapters to discuss their areas of expertise and their individual narratives. Join us for these captivating conversations as we celebrate our differences and share our joy for practicing cardiovascular medicine. We thank our project mentors Dr. Katie Berlacher and Dr. Nosheen Reza.

Video version - Career Flexibility in Cardiology https://youtu.be/ygNH6fcQ5ek Quoatables - Career Flexibility in Cardiology “You have to learn to live with ambivalence. You can’t do everything. You can’t do everything all at one time” “One of the most important things the College is behind and pushing, is that competency-based evaluation is what should be used in fellowship rather than this sort of cookie cutter approach where you have to do these many months of echo and this much of cath lab. So, I think flexibility moving from volume to competency is one push.” “Fellowship is daunting, and internal medicine residency is too, but I think culture is how we feel every day. And I think the more we increase flexibility the more that culture is going to shift. Notes - Career Flexibility in Cardiology Process of developing ACC Health Policy Statements These documents address issues that require ACC influence and usually involve a variety of institutions, governing bodies, and other stakeholders. ACC comes to an agreement on how they will approach this topic and shares it broadly. Most of the existing ACC health policy statements are disease-based instead of profession-based. The ACC Career Flexibility statement grew out of the diversity, equity, and inclusion task force, which is a standing committee. A variety of authors are included in health policy statements to reflect the perspectives of many different interest groups. All policy statements, including the one about career flexibility, are available online on JACC.org 1 Major Components of the ACC Career Flexibility Health Policy Statement There are 18 principles that highlight the most important aspects regarding career flexibility in cardiology.2 Flexibility allows for deceleration (decrease in work hours, responsibilities, etc.) and acceleration based on the needs of the physician. For example, during childbearing and rearing time periods, there could be a deceleration, which could accelerate when parenthood responsibilities have decreased. It does not only need to be based around parenting; physicians who are not parents also desire flexibility and enjoy spending time on activities other than their careers. These needs will be unique for each person.…
