Question #26 Ms. Priya Clampsia is a 58-year-old never-smoker with a history of hypertension. Her BMI is 29 kg/m2. She also mentions having pre-eclampsia during her pregnancy many years ago. She describes a predominately sedentary lifestyle and works as a receptionist. You see her in the clinic to discuss routine preventive care. Her most recent lipid panel results were LDL of 101 mg/dL, HDL of 45 mg/dL, and triglycerides of 190 mg/dL. What additional step will provide valuable information regarding her CVD risk profile? A Send additional lab workup including C-reactive protein and lipoprotein (a) B Measure her waist circumference C Assess her work stress D Ask her about history of preterm birth E B, C, and D Answer #26 Explanation The correct answer is E – measuring her waist circumference, assessing her occupational stress, and obtaining history about adverse pregnancy outcomes including preterm birth all add valuable information for CVD risk stratification. BMI is easily measured and can be used to define categories of body weight. However, body fat stores in visceral tissue carry higher risk than subcutaneous fat and therefore, waist circumference can be a simple way to measure global and abdominal fat. When waist circumference is ≥102 cm in men and ≥88 cm in women, weight reduction is advised. While these WHO thresholds are widely accepted in Europe, it is important to note that different cut-offs may be appropriate in different ethnic groups. Work stress is important to ascertain as well because there is preliminary evidence of the detrimental impact of worse stress on ASCVD health, independent of conventional risk factors and their treatment. Work stress is determined by job strain (i.e., the combination of high demands and low control at work) and effort-reward imbalance. Pre-eclampsia is associated with increase in CVD risk by factor of 1.5-2.7 compared with all women. Both preterm (RR 1.6) and still birth (RR 1.5) are also associated with a moderate increase in CVD risk. Taking a thorough pregnancy history is important in determining future cardiovascular risk in women. The ESC guidelines give a Class IIb (LOE B) recommendation that in women with history of premature or stillbirth, periodic screening for hypertension and DM may be considered. Of note, the 2018 ACC/AHA guidelines include preeclampsia and premature menopause (occurring at age <40 years) as risk-enhancing factors for statin therapy but state that the mechanism or cause of preterm birth is often unknown, so it is difficult to include it as a risk-enhancing factor. Choice A (sending additional lab workup including CRP and LPa) is incorrect. The ESC guidelines do not recommend using routine circulating biomarkers as they do not improve risk prediction and publication bias distorts the evidence (Class III, LOE B). While some biomarkers like lipoprotein (a) are promising, further work is still needed. Conversely, the 2019 ACC/AHA guidelines do include, if measured,

Question #20 Ms. Betty Blocker is a 60-year-old woman with a history of alcohol-related dilated cardiomyopathy who presents for follow up. She has been working hard to improve her health and is glad to report that she has just reached her 5-year sobriety milestone. Her current medications include metoprolol succinate 100mg daily, sacubitril-valsartan 97-103mg BID, spironolactone 25mg daily, and empagliflozin 10mg daily. She is asymptomatic at rest and up to moderate exercise, including chasing her grandchildren around the yard. A recent transthoracic echocardiogram shows recovered LVEF from previously 35% now to 60%. Ms. Blocker does not love taking so many medications and asks about discontinuing her metoprolol. Which of the following is the most appropriate response to Ms. Blocker’s request? A Since the patient is asymptomatic, metoprolol can be stopped without risk B Stopping metoprolol increases this patient’s risk of worsening cardiomyopathy regardless of current LVEF or symptoms C Because the LVEF is now >50%, the patient is now classified as having HFpEF and beta-blockade is no longer indicated; metoprolol can be safely discontinued D Metoprolol should be continued, but it is safe to discontinue either ARNi or spironolactone Answer #20 Explanation The correct answer is B – stopping metoprolol would increase her risk of worsening cardiomyopathy. Heart failure tends to be a chronically sympathetic state. The use of beta-blockers (specifically bisoprolol, metoprolol succinate, and carvedilol) targets this excess adrenergic output and has been shown to reduce the risk of death in patients with HFrEF. Beyond their mortality benefit, beta-blockers can improve LVEF, lessen the symptoms of HF, and improve clinical status. Therefore, in patients with HFrEF, with current or previous symptoms, use of 1 of the 3 beta blockers proven to reduce mortality (e.g., bisoprolol, carvedilol, sustained-release metoprolol succinate) is recommended to reduce mortality and hospitalizations (Class 1, LOE A). Beta-blockers in this setting provide a high economic value. Table 14 of the guidelines provides recommendations for target doses for GDMT medications. Specifically for beta blockers, those targets are 25-50mg twice daily for carvedilol (or 80mg once daily for the continuous release formulation), 200mg once daily for metoprolol succinate,

Case Summary - A Presentation of Heart Failure and Heart Block with Elusive Genetic Origins - Cambridge University A man in his 40s with a history of cardiac issues, including prior myocarditis and complete heart block, presented with progressive heart failure symptoms. Extensive cardiac investigations were conducted, revealing dilated left ventricle, mild to moderate left ventricular systolic dysfunction, normal coronaries, infero-lateral late gadolinium enhancement on cardiac MRI, and low-level uptake on PET-CT. Differential diagnosis included worsening underlying cardiomyopathy, recurrent myocarditis, tachycardia-related cardiomyopathy, pacemaker-induced LV dysfunction, and sarcoidosis. The patient's condition improved with heart failure medications, and cardiac MRI showed a mildly dilated left ventricle with moderate systolic dysfunction and active inflammation in the anterior wall. Further evaluation indicated a family history of hereditary cardiomyopathy, and the patient exhibited phenotypic features such as early-onset heart disease, arrhythmias, family history of cardiomyopathy, learning problems, intellectual disability, and mild proximal myopathy. Genetic testing confirmed a LAMP2 mutation, leading to the diagnosis of Danon disease.

Question #25 Please choose the CORRECT statement from the ones below.ACAC scoring can be considered to improve ASCVD risk classification around treatment decision thresholds.BPatients with type 1 or type 2 diabetes are considered very high CV risk, regardless of comorbidities and other risk factors.CCKD does not increase the cardiovascular risk in the absence of other risk factors.DMen and women older than 65 years old are at high cardiovascular risk. Answer #25 ExplanationOption A is correct. Coronary artery calcium (CAC) scoring can reclassify CVD risk upwards and downwards in addition to conventional risk factors and may thus be considered in men and women with calculated risks around decision thresholds (Class IIb, Level B). If CAC is detected, its extent should be compared with what would be expected for a patient of the same sex and age. CAC scoring does not provide direct information on total plaque burden or stenosis severity and can be low or even zero in middle-aged patients with soft non-calcified plaque.Option B is false. Not all patients with diabetes are very high risk by default.·       Moderate risk: well controlled diabetes, <10 years duration, without evidence of target organ damage and no additional ASCVD risk factors.·       High risk: patients not fulfilling the criteria above, without ASCVD and/or severe target organ damage.·       Very high risk: diabetic patients with established ASCVD and/or severe target organ damage.Severe target organ damage is defined by:·       eGFR <45 mL/min/1.73 m2·       eGFR 45-59 mL/min/1.73 m2 and microalbuminuria (albumin-to-creatinine ratio, ACR 30 -300 mg/g)·       Proteinuria (ACR >300 mg/g)·       Presence of microvascular disease in at least 3 different sites (e.g., microalbuminuria + retinopathy + neuropathyOption C is false. CKD carries at least a high CVD risk even in the absence of diabetes or ASCVD.·       Moderate CKD carries a high CVD risk: o   eGFR 30−44 mL/min/1.73 m2 and ACR <30o   eGFR 45−59 mL/min/1.73 m2 and ACR 30−300o   eGFR ≥60 mL/min/1.73 m2 and ACR >300·       Severe CKD carries a very high CVD risk:o   eGFR<30 mL/min/1.73 m2o   eGFR 30−44 mL/min/1.73 m2 and ACR >30 Option D is false. There is an age difference between men and women with regards to cardiovascular risk. Age is a major CVD risk driver, but age cutoffs should be used with flexibility.·       Women < 50 years-old and men < 40 years old are usually at low 10-year CVD risk. It is still important to be aware of unfavorable modifiable risk factors that can sharply increase their lifetime CVD risk.·       Women > 75 years-old and men > 65 years-old are usually at high 10-year CVD risk.·       Only between the ages of 55 – 75 years in women and 40 – 65 years in men does the 10-year CVD risk vary around commonly used thresholds for intervention. Of note:·       In younger, apparently healthy patients, we also discuss lifetime CVD risk estimates since 10-year risk assessments often underestimate risk.

The following question refers to Section 7.1 of the 2022 AHA/ACC/HFSA Guideline for the Management of Heart Failure. The question is asked by New York Medical College medical student and CardioNerds Intern Akiva Rosenzveig, answered first by Lahey Hospital and Medical Center internal medicine resident and CardioNerds Academy House Faculty Leader Dr. Ahmed Ghoneem, and then by expert faculty Dr. Clyde Yancy.

Question #19 Ms. M is a 36-year-old G1P1 woman 6 months postpartum who was diagnosed with peripartum cardiomyopathy at the end of her pregnancy. She is presenting for a follow up visit today and notes that while her leg edema has resolved, she continues to have dyspnea when carrying her child up the stairs. She also describes significant difficulty sleeping, though denies orthopnea, and notes she is not participating in hobbies she had previously enjoyed. She is currently prescribed a regimen of sacubitril-valsartan, metoprolol succinate, spironolactone, and empagliflozin.  What are the next best steps? A Screen for depression B Counsel her to follow a strict low sodium diet with goal of < 1.5g Na daily C Recommend exercise therapy and refer to cardiac rehabilitation D A & C Answer #19 Explanation The correct answer is D – both A (screening for depression) and C (referring to cardiac rehabilitation) are appropriate at this time. Choice A is correct. Depression is a risk factor for poor self-care, rehospitalization, and all-cause mortality among patients with HF. Interventions that focus on improving HF self-care have been reported to be effective among patients with moderate/severe depression with reductions in hospitalization and mortality risk. Social isolation, frailty, and marginal health literacy have similarly been associated with poor HF self-care and worse outcomes in patients with HF. Therefore, in adults with HF, screening for depression, social isolation, frailty, and low health literacy as risk factors for poor self-care is reasonable to improve management (Class 2a, LOE B-NR).  Choice C is correct. In patients with HF, cardiac rehabilitation has a Class 2a recommendation (LOE B-NR) to improve functional capacity, exercise tolerance, and health-related QOL; exercise training (or regular physical activity) for those able to participate has a Class 1 recommendation (LOE A) to improve functional status, exercise performance, and QOL. Choice B is incorrect. For patients with stage C HF, avoiding excessive sodium intake is reasonable to reduce congestive symptoms (Class 2a, LOE C-LD). However, strict sodium restriction does not have strong supportive data and is not recommended. There are ongoing studies to better understand the impact of sodium restriction on clinical outcomes and quality of life. The AHA currently recommends a reduction of sodium intake to <2300 mg/d for general cardiovascular health promotion; however, there are no trials to support this level of restriction in patients with HF. Main Takeaway Depression is a risk factor for poor HF self-care and worse outcomes in pat...

CardioNerds (Daniel Ambinder) join Dr. Tomio Tran, Dr. Vid Yogeswaran, and Dr. Amanda Cai from the University of Washington for a break from the rain at the waterfront near Pike Place Market. They discuss the following case: A 46-year-old woman presents with cardiac arrest and was found to have cor triatriatum sinistrum (CTS). CTS is a rare congenital cardiac malformation in which the left atrium is divided by a fenestrated membrane, which can restrict blood flow and cause symptoms of congestive heart failure. Rarely, the condition can present in adulthood. To date, there have been no cases of sudden cardiac death attributed to CTS. Dr. Jill Steiner provides the E-CPR for this episode.

Case Media - A Sinister Cause of Sudden Cardiac Death – University of Washington A 40-year-old woman with a history of recurrent exertional syncope had sudden loss of consciousness while kissing her partner. The patient received bystander CPR while 911 was called. EMS arrived within 10 minutes of the call and found the patient apneic and unresponsive. Initial rhythm check showed narrow complex tachycardia at a rate of 136 BPM. ROSC was eventually achieved. A 12-lead ECG showed that the patient was in atrial fibrillation with rapid ventricular rate. The patient was intubated and brought to the emergency department. The patient spontaneously converted to sinus rhythm en route to the hospital. In the emergency department, vital signs were remarkable for hypotension (76/64 mmHg) and sinus tachycardia (110 BPM). The physical exam was remarkable for an inability to follow commands. Laboratory data was remarkable for hypokalemia (2.5 mmol/L), transaminitis (AST 138 units/L, ALT 98 units/L), acidemia (pH 7.12), and hyperlactatemia (11.2 mmol/L). CT scan of the chest revealed a thin membrane within the left atrium. Transthoracic echocardiogram showed normal biventricular size and function, severe tricuspid regurgitation, pulmonary artery systolic pressure of 93 mmHg, and the presence of a membrane within the left atrium with a mean gradient of 25 mmHg between the proximal and distal left atrial chambers. Vasopressors and targeted temperature management were initiated. The patient was able to be re-warmed with eventual discontinuation of vasopressors, however she had ongoing encephalopathy and seizures concerning for hypoxic brain injury. There was discussion with the adult congenital heart disease team about next steps in management, however the patient was too sick to undergo any definitive treatment for the intracardiac membrane within the left atrium. The patient developed ventilator associated pneumonia and antibiotics were initiated. The patient ultimately developed  bradycardia and pulseless electrical activity; ROSC was unable to be achieved, resulting in death. Autopsy was remarkable for the presence of a fenestrated intracardiac membrane within the left atrium and lack of other apparent congenital heart defects. There was right ventricular hypertrophy and pulmonary artery intimal thickening with interstitial fibrosis suggestive of pulmonary hypertension. There were bilateral acute subsegmental pulmonary emboli present. The cause of death was declared to be arrhythmia in the setting of pulmonary hypertension and right s...

Question #24 A 65-year-old man with a history of ischemic stroke 6 months ago presents to cardiology clinic to establish care. An event monitor was negative for atrial fibrillation and TTE with agitated saline study was negative for a patent foramen ovale. Therefore, his ischemic stroke was presumed to be non-cardioembolic in origin. He is currently taking lisinopril 5 mg daily for hypertension (BP in clinic is 115/70) and atorvastatin 40 mg daily. He has no history of significant gastrointestinal or other bleeding. What do you recommend next?AStart apixaban 5 mg BIDBIncrease lisinopril to 10 mg dailyCStart aspirin 81 mg dailyDStart aspirin 81 mg daily and clopidogrel 75 mg dailyEStart aspirin 81 mg daily and ticagrelor 90 mg BID Answer #24 ExplanationThe correct answer is C – start aspirin 81mg daily.For the secondary prevention of non-cardioembolic ischemic stroke or TIA, anti-platelet therapy is recommended with aspirin only (75-150 mg/day), dipyridamole + aspirin (slightly superior to aspirin), or clopidogrel alone (slightly superior to aspirin) (Class I, LOE A).DAPT with aspirin and clopidogrel or aspirin and ticagrelor should be considered in the immediate period after a minor ischemic stroke or TIA (3 weeks after event, Class IIa), but not 6 months after an ischemic stroke. Dual antiplatelet therapy with aspirin and clopidogrel increases bleeding risk without a significant benefit over either agent alone. Dual antiplatelet therapy with aspirin and ticagrelor increases bleeding risk, but does not improve disability incidence.Oral anticoagulation would be recommended for a cardioembolic stroke, which does not fit the clinical picture.His BP is well controlled so increasing lisinopril is not necessary.Main TakeawayFor the secondary prevention of an ischemic stroke or TIA, anti-platelet therapy with aspirin, aspirin + dipyridamole, or clopidogrel alone is recommended.Guideline Loc.6.3, page 3296-3297 CardioNerds Decipher the Guidelines - 2021 ESC Prevention SeriesCardioNerds Episode PageCardioNerds AcademyCardionerds Healy Honor RollCardioNerds Journal ClubSubscribe to The Heartbeat Newsletter!Check out CardioNerds SWAG!Become a CardioNerds Patron!

Question #18 Ms. AH is a 48-year-old woman who presents with a 3-month history of progressively worsening exertional dyspnea and symmetric bilateral lower extremity edema. She has no history of recent upper respiratory symptoms or chest pain. She denies any tobacco, alcohol, or recreational drug use. There is no family history of premature CAD or HF. On exam, her blood pressure is 110/66 mmHg, heart rate is 112 bpm, and respiration rate is 18 breaths/min with oxygen saturation of 98% on ambient room air. She has jugular venous distention of about 12cm H2O, bibasilar crackles, an S3 heart sound, and bilateral lower extremity edema. Complete blood count, serum electrolytes, kidney function tests, liver chemistry tests, glucose level, iron studies, and lipid levels are unremarkable. An electrocardiogram shows sinus tachycardia with normal intervals and no conduction delays. A transthoracic echocardiogram demonstrates a left ventricular ejection fraction of 25%, normal right ventricular size and function, and no valvular abnormalities. Which of the following diagnostic tests has a Class I indication for further evaluation? A Cardiac catheterization B Referral for genetic counseling C Thyroid function studies D Cardiac MRI Answer #18 Explanation  The correct answer is C – thyroid function studies have a Class 1 indication for the evaluation of HF.  The common causes of HF include coronary artery disease, hypertension, and valvular heart disease. Other causes may include arrhythmia-associated, toxic, inflammatory, metabolic including both endocrinopathies and nutritional, infiltrative, genetic, stress induced, peripartum, and more. It is important to evaluate for the etiology of a given patient’s heart failure as diagnosis may have implications for treatment, counseling, and family members. For patients who are diagnosed with HF, laboratory evaluation should include complete blood count, urinalysis, serum electrolytes, blood urea nitrogen, serum creatinine, glucose, lipid profile, liver function tests, iron studies, and thyroid-stimulating hormone to optimize management (Class 1, LOR C-EO). These studies provide important information regarding comorbidities, suitability for and adverse effects of treatments, potential causes or confounders of HF, and severity and prognosis of HF.

Pearls - ACHD: Interventional Cardiology The ductus arteriosus, which is formed from the distal portion of the left sixth arch, is key to fetal circulation because it allows blood to bypass Transcatheter pulmonic valve replacement (TPVR) is a treatment for many ACHD patients that can spare them repeat sternotomies. This is important as many ACHD patients hava already undergone multiple surgeries in their childhood.   Before any ACHD cardiology intervention, appropriate imaging (TEE, TTE, Cardiac MRI, Cardiac CTA, and/or 3D printing) is imperative to understanding the relevant anatomy and hemodynamics to guide procedural indication and planning.    As with other structural interventions, consider a SENTINEL device (cerebral embolic protection system) to provide embolic protection in procedures that could lead to debris/embolic dislodgement when appropriate. Sinus venosus defects can be repaired via a transcatheter approach with a covered stent in the superior vena cava (SVC).   Consider using 3D printing or 3D digital imaging when preparing for complex ACHD interventions.    Notes- ACHD: Interventional Cardiology 1. When considering a patient for TPVR there are 3 types of landing zones for pulmonic valves in ACHD patients:    Pulmonary conduits or homografts. These are typically seen in patients with TOF or prior Ross or Rastelli procedure. These may be calcified and stenotic and so pre-dilatation is often needed before valve replacement.   Bioprosthetic Valves. (Valve in Valve TPVR) Native outflow tract 2. What are some of the more severe complications to consider when talking to an ACHD patient about a TPVR?   Coronary artery compression Conduit rupture Vessel injury (including the pulmonary bed) Valve embolization Endocarditis 3. What are some of the hemodynamic measurements one would want to pay attention to in a patient with a Fontan heart?    You will see higher CVPs in patients with a Fontan palliation.

They discuss common ACHD pathologies that benefit from interventional procedures such as transcatheter pulmonic valve replacement (TPVR) and share new advancements in transcatheter approaches to correct sinus venosus defects. They end with a brief discussion on how to become an adult cardiology interventionalist that performs ACHD interventions. Episode notes were drafted by Dr. Victoria Thomas. Audio editing by CardioNerds Academy Intern, student doctor Akiva Rosenzveig.  The CardioNerds Adult Congenital Heart Disease (ACHD) series provides a comprehensive curriculum to dive deep into the labyrinthine world of congenital heart disease with the aim of empowering every CardioNerd to help improve the lives of people living with congenital heart disease. This series is multi-institutional collaborative project made possible by contributions of stellar fellow leads and expert faculty from several programs, led by series co-chairs, Dr. Josh Saef, Dr. Agnes Koczo, and Dr. Dan Clark. The CardioNerds Adult Congenital Heart Disease Series is developed in collaboration with the Adult Congenital Heart Association, The CHiP Network, and Heart University.

Pearls - ACHD: Interventional Cardiology The ductus arteriosus, which is formed from the distal portion of the left sixth arch, is key to fetal circulation because it allows blood to bypass Transcatheter pulmonic valve replacement (TPVR) is a treatment for many ACHD patients that can spare them repeat sternotomies. This is important as many ACHD patients hava already undergone multiple surgeries in their childhood.   Before any ACHD cardiology intervention, appropriate imaging (TEE, TTE, Cardiac MRI, Cardiac CTA, and/or 3D printing) is imperative to understanding the relevant anatomy and hemodynamics to guide procedural indication and planning.    As with other structural interventions, consider a SENTINEL device (cerebral embolic protection system) to provide embolic protection in procedures that could lead to debris/embolic dislodgement when appropriate. Sinus venosus defects can be repaired via a transcatheter approach with a covered stent in the superior vena cava (SVC).   Consider using 3D printing or 3D digital imaging when preparing for complex ACHD interventions.    Notes- ACHD: Interventional Cardiology 1. When considering a patient for TPVR there are 3 types of landing zones for pulmonic valves in ACHD patients:    Pulmonary conduits or homografts. These are typically seen in patients with TOF or prior Ross or Rastelli procedure. These may be calcified and stenotic and so pre-dilatation is often needed before valve replacement.   Bioprosthetic Valves. (Valve in Valve TPVR) Native outflow tract 2. What are some of the more severe complications to consider when talking to an ACHD patient about a TPVR?   Coronary artery compression Conduit rupture Vessel injury (including the pulmonary bed) Valve embolization Endocarditis 3. What are some of the hemodynamic measurements one would want to pay attention to in a patient with a Fontan heart?    You will see higher CVPs in patients with a Fontan palliation.
