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.

Question #36 A 50-year-old woman presents to establish care. Her medical history includes COPD, prediabetes, and hypertension. She is being treated with chlorthalidone, amlodipine, lisinopril, and a tiotropium inhaler. She denies chest pain, dyspnea on exertion, or lower extremity edema. On physical exam, blood pressure is 154/88 mmHg, heart rate is 90 beats/min, and respiration rate is 22 breaths/min with an oxygen saturation of 94% breathing ambient room air. BMI is 36 kg/m2. Jugular venous pulsations are difficult to assess due to her body habitus. Breath sounds are distant, with occasional end-expiratory wheezing. Heart sounds are distant, and extra sounds or murmurs are not detected. Extremities are warm and without peripheral edema. B-type natriuretic peptide level is 28 pg/mL (28 ng/L). A chest radiograph shows increased radiolucency of the lungs, flattened diaphragms, and a narrow heart shadow consistent with COPD. An electrocardiogram shows evidence of left ventricular hypertrophy. The echocardiogram showed normal LV and RV function with no significant valvular abnormalities. In which stage of HF would this patient be classified?AStage A: At Risk for HFBStage B: Pre-HFCStage C: Symptomatic HFDStage D: Advanced HF Answer #36 Explanation The correct answer is A – Stage A or at risk for HF. This asymptomatic patient with no evidence of structural heart disease or positive cardiac biomarkers for stretch or injury would be classified as Stage A or “at risk” for HF. The ACC/AHA stages of HF emphasize the development and progression of disease with specific therapeutic interventions at each stage. Advanced stages and disease progression are associated with reduced survival. The stages were revised in this edition of guidelines to emphasize new terminologies of “at risk” for Stage A and “pre-HF” for Stage B....

  • 396. Case Report: Unmasking Constrictive Pericarditis Using Multimodality Imaging – University of Nebraska
    Oct 21 2024
    CardioNerds (Dr. Dan Ambinder and Dr. Rick Ferraro) join Dr. Mansi Oberoi and Dr. Mohan Gudiwada from the University of Nebraska Medical Center discuss a case of constrictive pericarditis. Expert commentary is provided by Dr. Adam Burdorf, who serves as the Program Director for the Cardiovascular Medicine Fellowship at the University of Nebraska Medical Center. The case discussed involves a 76-year-old woman with a history of monoclonal gammopathy of undetermined significance, chronic obstructive pulmonary disease, type 2 diabetes mellitus, and squamous cell carcinoma was admitted to the hospital for worsening shortness of breath, swelling in lower extremities, hyponatremia, and urinary tract infection. CT chest to evaluate for pulmonary embolism showed incidental pericardial calcifications; the heart failure team was consulted for the management of her decompensated heart failure. Echo images were nondiagnostic. Subsequent invasive hemodynamic monitoring showed elevated right and left-sided filling pressures, diastolic equalization of LV and RV pressures, and positive RV square root sign with ventricular interdependence. Cardiac MRI showed septal flattening on deep inspiration and septal bounce, suggestive of interventricular dependence. After a heart team discussion and with shared-decision making the patient opted for medical management owing to her comorbidities and frailty.

  • 395. Beyond the Boards: Channelopathies with Dr. Michael Ackerman
    Oct 10 2024
    Dr. Amit Goyal, along with episode chair Dr. Dinu Balanescu (Mayo Clinic, Rochester), and FIT leads Dr. Sonu Abraham (University of Kentucky) and Dr. Natasha Vedage (MGH), dive into the fascinating topic of channelopathies with Dr. Michael Ackerman, a genetic cardiologist and professor of medicine, pediatrics, and pharmacology at Mayo Clinic, Rochester, Minnesota. Using a case-based approach, they review the nuances of diagnosis and treatment of channelopathies, including Brugada syndrome, catecholaminergic polymorphic ventricular tachycardia (CPVT), and long QT syndrome. Dr. Sonu Abraham drafted show notes. Audio engineering for this episode was expertly handled by CardioNerds intern, Christiana Dangas. The CardioNerds Beyond the Boards Series was inspired by the Mayo Clinic Cardiovascular Board Review Course and designed in collaboration with the course directors Dr. Amy Pollak, Dr. Jeffrey Geske, and Dr. Michael Cullen. CardioNerds Beyond the Boards SeriesCardioNerds Episode PageCardioNerds AcademyCardionerds Healy Honor Roll CardioNerds Journal ClubSubscribe to The Heartbeat Newsletter!Check out CardioNerds SWAG!Become a CardioNerds Patron! Pearls and Quotes - Channelopathies One cannot equate the presence of type 1 Brugada ECG pattern to the diagnosis of Brugada syndrome. Clinical history, family history, and/or genetic testing results are required to make a definitive diagnosis. The loss-of-function variants in the SCN5A gene, which encodes for the α-subunit of the NaV1.5 sodium channel, is the only Brugada susceptibility gene with sufficient evidence supporting pathogenicity. Exertional syncope is an “alarm” symptom that demands a comprehensive evaluation with 4 diagnostic tests: ECG, echocardiography, exercise treadmill test, and Holter monitor. Think of catecholaminergic polymorphic ventricular tachycardia (CPVT) in a patient with exertional syncope and normal EKG! ICD therapy is never prescribed as monotherapy in patients with CPVT. Medical therapy with a combination of nadolol plus flecainide is the current standard of care. Long QT syndrome is one of the few clinical scenarios where genetic testing clearly guides management, particularly with respect to variability in beta-blocker responsiveness. Notes - Channelopathies 1. What are the diagnostic criteria for Brugada syndrome (BrS)? Three repolarization patterns are associated with Brugada syndrome in the right precordial leads (V1-V2): Type 1: Prominent coved ST-segment elevation displaying J-point amplitude or ST-segment elevation ≥2 mm, followed by a negative T wave. Type 2/3: Saddleback ST-segment configuration with variable levels of ST-segment elevation. It is important to note that only a type 1 pattern is diagnostic for Brugada syndrome, whereas patients with type 2/3 patterns may benefit from further testing. The Shanghai score acknowledges that relying solely on induced type 1 ECG changes has limitations. Therefore, one cannot equate the presence of a type 1 Brugada ECG pattern alone to the diagnosis of Brugada syndrome. The score suggests incorporating additional information—such as clinical history, family history, and/or genetic testing results—to achieve a definitive diagnosis. 2. What is the significance of genetic testing in Brugada syndrome? There are 23 alleged Brugada syndrome susceptibility genes published with varying levels of evidence. However, only one gene mutation, the loss-of-function variants in the SCN5A gene encoding for the α-subunit of the NaV1.5 sodium channel, is considered to have sufficient evidence. The overall yield of BrS genetic testing is 20%. The presence of PR prolongation (>200 ms) along with type I EKG pattern increases the yield to 40%. On the contrary, in the presence of a normal PR interval, the likelihood of SCN5A positivity drops to <10%. 3. How would you risk-stratify a patient with Brugada syndrome?

  • 393. SGLT Inhibitors: Clinical Implementation of SGLT Inhibitors with Dr. Alison Bailey
    Oct 1 2024
    CardioNerds Drs. Jason Feinman, Gurleen Kaur, and Rick Ferraro discuss the implementation of SGLT inhibitors in clinical practice with Dr. Alison Bailey. Notes were drafted by Dr. Jason Feinman. In this episode, we discuss the implementation of SGLTi in clinical practice scenarios, including for individuals with heart failure regardless of ejection fraction, those with chronic kidney disease, and those with diabetes mellitus. The group also discusses important side effects to monitor for, as well as how to counsel patients when prescribing these medications. This episode was produced in collaboration with the American Society of Preventive Cardiology (ASPC) with independent medical education grant support from Lexicon Pharmaceuticals. CardioNerds Prevention PageCardioNerds Episode PageCardioNerds AcademyCardionerds Healy Honor Roll CardioNerds Journal ClubSubscribe to The Heartbeat Newsletter!Check out CardioNerds SWAG!Become a CardioNerds Patron! Pearls - Clinical Implementation of SGLT Inhibitors For patients with heart failure with reduced ejection fraction, SGLT inhibitors reduce the composite outcome of cardiovascular death or heart failure hospitalization by 25%. SGLT inhibitors can be safely started in patients with an eGFR as low as 20. There are ongoing trials investigating the safety of these medications in individuals with eGFR lower than 20 or those who are receiving dialysis. An eGFR decrease of 3-5 ml/min on average is expected after starting an SGLTi, but this will stabilize over time and provides protective effects of renal dysfunction in the long run. Early data that suggested an association between SGLTi and bacterial UTI development hasn’t panned out in the long run, but there is an association between SGLTi and the development of either genital mycotic infections or yeast infections. Perineal hygiene is important to prevent the development of either. A patient-centered, shared decision-making approach should guide the choice of agents for individuals with type 2 diabetes mellitus. In certain patients, it may be reasonable to choose an SGLTi as the first-line agent. Show notes - Clinical Implementation of SGLT Inhibitors What is the data supporting the use of SGLTi in HFpEF? The EMPEROR-Preserved and DELIVER trials investigated the impact of empagliflozin and dapagliflozin, respectively, on cardiovascular outcomes in patients with mildly reduced or preserved ejection fraction. The SOLOIST-WHF trial investigated a combined SGLT1/2 inhibitor, sotagliflozin, in patients with recently worsening heart failure, irrespective of ejection.SGLTi have been demonstrated to reduce the risk of cardiovascular death or worsening heart failure, including heart failure hospitalization, in these individuals. A meta-analysis of the EMPEROR-Preserved and DELIVER trials demonstrated a hazard ratio of 0.80 for cardiovascular death or first hospitalization for heart failure for empagliflozin or dapagliflozin over placebo in the setting of HFpEF. What is the data supporting the use of SGLTi in HFrEF? In addition to the SOLOIST-WHF trial that was previously discussed, the EMPEROR-HF and DAPA-HF investigated the impact of SGLTi medications in patients with HFrEF. In patients with HFrEF, SGLTi medications have been demonstrated to reduce the risk of either cardiovascular death or heart failure hospitalization. Dapagliflozin and empagliflozin had a pooled risk reduction of all-cause death of 13%, a pooled risk reduction of cardiovascular death of 14%, and a 26% reduction in the combination of CV death or first hospitalization for heart failure. What is the expected impact of SGLTi on renal function? Dapagliflozin, empagliflozin, sotagliflozin, ertugliflozin, and canagliflozin have all been studied for their impact on renal dysfunction in individuals both with and without diabetes.

  • 392. Case Report: Heart Failure Out of the Blue, A Case of Cobalt Cardiomyopathy – Georgetown University
    Sep 23 2024
    CardioNerds (Amit Goyal) join Dr. Merna Hussien, Dr. Akhil Kallur, Dr. Abhinav Saxena, and Dr. Brody Deb from the MedStar Georgetown - Washington Hospital Center in DC for a stroll around Rock Creek Park as they discuss an unusual case of cobalt cardiomyopathy. Expert commentary is provided by Dr. Nana Afari Armah. Episode audio was edited by CardioNerds Intern Christiana Dangas. The case is of a middle-aged woman with a past medical history of hypertension, hyperlipidemia, and bilateral hip replacements, who presented with subacute progressive exertional dyspnea, orthopnea, and constitutional symptoms and was found to have SCAI Stage C cardiogenic shock. Transthoracic echocardiogram showed severely reduced left ventricular ejection fraction (LVEF, 20-25%) and a moderate pericardial effusion. Cardiac catheterization revealed biventricular failure with elevated filling pressures. A cardiac MRI showed diffuse late gadolinium enhancement (LGE) in the left ventricle. Endomyocardial biopsy showed nonspecific chronic inflammation. However, the evidence of mitochondrial heavy metal toxicity and elevated cobalt levels made the diagnosis of cobalt cardiomyopathy. The patient underwent revision of hip joint implants to ceramic implants and started chelation therapy. However, due to persistent stage D heart failure despite normalization of cobalt levels, she underwent orthotropic heart transplantation.

Case MEdia - Cobalt Cardiomyopathy Pearls - Cobalt Cardiomyopathy A good history goes a long way in diagnosing non-ischemic cardiomyopathy (NICM). Common problems can have uncommon presentations requiring a high degree of suspicion for diagnosis. Imaging features can overlap between causes of NICM. History helps in targeting further histological workup and uncovering the root cause. Multidisciplinary effort is essential in making a rare diagnosis.

From Hip to Heart: A Comprehensive Evaluation of an Infiltrative Cardiomyopathy. CJC Open. 2021 Nov 1;3(11):1392–5. Notes - Cobalt Cardiomyopathy How common is cobalt cardiomyopathy? When should it be suspected? Cobalt cardiomyopathy is incredibly rare, with only a handful of reported cases. 2 It is also known as beer drinkers’ cardiomyopathy, as cobalt was added to beer for fortification in Quebec 3, where it was first reported. Cobalt cardiomyopathy is characterized by its rapidly progressive nature, the presence of low voltages on EKG, and diffuse infiltration. Patients also complained of a previous history of anorexia and weight loss and were found to have polycythemia and thyroid abnormalities on labs. This syndrome was very similar to wet beriberi except for the absence of a therapeutic response to thiamine. Taken from - 2 Later, this was noted in patients with total metal hip arthroplasty 4–6, especially in patients with metal-on-metal hip arthroplasty, which led to corrosion and leakage of cobalt into the bloodstream. The syndrome in these patients was similar to those in beer drinkers from Quebec. This figure, taken from 2, shows the reports of Cobalt cardiomyopathy after cobalt alloy prostheses. [HX1] What is the pathophysiology of cobalt cardiomyopathy? Cobalt has a variety of effects on the heart, both microscopically and biochemically.Cobalt may have multiple calcium-mediated cardiac effects and may also interfere with the Krebs cycle and ATP generation by mitochondria.

    The following question refers to Section 2.2 of the 2022 AHA/ACC/HFSA Guideline for the Management of Heart Failure.The question is asked by University of Colorado internal medicine resident Dr. Hirsh Elhence, answered first by University of Chicago advanced heart failure cardiologist and Co-Chair for the CardioNerds Critical Care Cardiology Series Dr. Mark Belkin, and then by expert faculty Dr. Mark Drazner.Dr. Drazner is an advanced heart failure and transplant cardiologist, Professor of Medicine, and Clinical Chief of Cardiology at UT Southwestern. He is the President of the Heart Failure Society of America.The Decipher the Guidelines: 2022 AHA / ACC / HFSA Guideline for The Management of Heart Failure series was developed by the CardioNerds and created in collaboration with the American Heart Association and the Heart Failure Society of America.

Question #35 A 50-year-old woman with a history of congestive heart failure, hypertension, type 2 diabetes mellitus, and obstructive sleep apnea presents to the outpatient clinic to follow up on her heart failure management. One year prior, echocardiogram showed an ejection fraction of 30% with an elevated BNP, for which she was started on appropriate GDMT. Repeat echocardiogram today showed an EF of 50%. Which of the following best describes her heart failure status? A HFrEF (HF with reduced EF) B HFimpEF (HF with improved EF) C HFmrEF (HF with mildly reduced EF) D HFpEF (HF with preserved EF) Answer #35 Explanation The correct answer is B – HFimpEF, or heart failure with improved ejection fraction, best describes her current heart failure status. Left ventricular ejection fraction is an important factor in classifying heart failure given differences in prognosis, response to treatment, and use in clinical trial enrollment criteria. The classification of heart failure by EF (adopted from the Universal Definition of HF): – HFrEF (HF with reduced EF): LVEF ≤40% – HFimpEF (HF with improved EF): previous LVEF ≤40%, a ≥10% increase from baseline LVEF, and a second measurement of LVEF >40%. – HFmrEF (HF with mildly reduced EF): LVEF 41%–49%, andevidence of spontaneous or provokable increased LV filling pressures (e.g., elevated natriuretic peptide, noninvasive and invasive hemodynamic measurement) – HFpEF (HF with preserved EF): LVEF ≥50%, and evidence of spontaneous or provokable increased LV filling pressures (e.g., elevated natriuretic peptide, noninvasive and invasive hemodynamic measurement) Patients with HFmrEF are usually in a dynamic state of improving from HFrEF or deteriorating towards HFrEF. Therefore, patients with HFmrEF may benefit from follow-up evaluation of systolic function and etiology of sub-normal EF. Improvements in EF are associated with better outcomes but do not indicate full myocardial recovery or normalization of LV function. Indeed, structural and functional abnormalities such as LV dilation and systolic or diastolic dysfunction often persist. Moreover, EF may remain dynamic with fluctuations in either direction depending on factors such as GDMT adherence and re-exposure to cardiotoxic agents. As such, the term heart failure with “improved EF” was deliberately chosen over “recovered EF” and “preserved EF”. Importantly, in patients with HFimpEF while on GDMT, the EF may decrease after withdrawal of GDMT. Main Takeaway
