Question #6 Mr. D is a 50-year-old man who presented two months ago with palpations and new onset bilateral lower extremity swelling. Review of systems was negative for prior syncope. On transthoracic echocardiogram, he had an LVEF of 40% with moderate RV dilation and dysfunction. EKG showed inverted T-waves and low-amplitude signals just after the QRS in leads V1-V3. Ambulatory monitor revealed several episodes non-sustained ventricular tachycardia with a LBBB morphology. He was initiated on GDMT and underwent genetic testing that revealed 2 desmosomal gene variants associated with arrhythmogenic right ventricular cardiomyopathy (ARVC). Is the following statement true or false? “ICD implantation is inappropriate at this time because his LVEF is >35%” True   False   Answer #6 Explanation This statement is False. ICD implantation is reasonable to decrease sudden death in patients with genetic arrhythmogenic cardiomyopathy with high-risk features of sudden death who have an LVEF ≤45% (Class 2a, LOE B-NR). While the HF guidelines do not define high-risk features of sudden death, the 2019 HRS expert consensus statement on evaluation, risk stratification, and management of arrhythmogenic cardiomyopathy identify major and minor risk factors for ventricular arrhythmias as follows: Major criteria: NSVT, inducibility of VT during EPS, LVEF ≤ 49%. Minor criteria: male sex, >1000 premature ventricular contractions (PVCs)/24 hours, RV dysfunction, proband status, 2 or more desmosomal variants. According to the HRS statement, high risk is defined as having either three major, two major and two minor, or one major and four minor risk factors for a class 2a recommendation for primary prevention ICD in this population (LOE B-NR). Based on these criteria, our patient has 2 major risk factors (NSVT & LVEF ≤ 49%), and 3 minor risk factors (male sex, RV dysfunction, and 2 desmosomal variants) for ventricular arrhythmias. Therefore, ICD implantation for primary prevention of sudden cardiac death is reasonable. Decisions around ICD implantation for primary prevention remain challenging and depend on estimated risk for SCD, co-morbidities, and patient preferences, and so should be guided by shared decision making weighing the possible benefits against the risks,

Question #5 Ms. L is a 65-year-old woman with nonischemic cardiomyopathy with a left ventricular ejection fraction (LVEF) of 35%, hypertension, and type 2 diabetes mellitus. She has been admitted to the hospital with decompensated heart failure (HF) twice in the last six months and admits that she struggles to understand how to take her medications and adjust her sodium intake to prevent this.  Which of the following interventions has the potential to decrease the risk of rehospitalization and/or improve mortality? A Access to a multidisciplinary team (physicians, nurses, pharmacists, social workers, care managers, etc) to assist with management of her HF   B Engaging in a mobile app aimed at improving HF self-care   C Vaccination against respiratory illnesses   D A & C   Answer #5   The correct answer is D – both A (access to a multidisciplinary team) and C (vaccination against respiratory illness).   Choice A is correct. Multidisciplinary teams involving physicians, nurses, pharmacists, social workers, care managers, dieticians, and others, have been shown in multiple RCTs, metanalyses, and Cochrane reviews to both reduce hospital admissions and all-cause mortality. As such, it is a class I recommendation (LOE A) that patients with HF should receive care from multidisciplinary teams to facilitate the implementation of GDMT, address potential barriers to self-care, reduce the risk of subsequent rehospitalization for HF, and improve survival. Choice B is incorrect.  Self-care in HF comprises treatment adherence and health maintenance behaviors. Patients with HF should learn to take medications as prescribed, restrict sodium intake, stay physically active, and get vaccinations. They also should understand how to monitor for signs and symptoms of worsening HF, and what to do in response to symptoms when they occur. Interventions focused on improving the self-care of HF patients significantly reduce hospitalizations and all-cause mortality as well as improve quality of life. Therefore, patients with HF should receive specific education and support to facilitate HF self-care in a multidisciplinary manner (Class I, LOE B-R). However, the method of delivery and education matters. Reinforcement with structured telephone support has been shown to be effective. In contrast the efficacy of mobile health-delivered educational interventions in improve self-care in patients with HF remains uncertain. Choice C is correct. In patients with HF, vaccinating against respiratory illnesses is reasonable to reduce mortality (Class 2a, LOE B-NR). For example, administration of the influenza vaccine in HF patients has been shown to reduce...

Question #4 Mr. Stevens is a 55-year-old man who presents with progressively worsening dyspnea on exertion for the past 2 weeks. He has associated paroxysmal nocturnal dyspnea, intermittent exertional chest pressure, and bilateral lower extremity edema. Otherwise, Mr. Stevens does not have any medical history and does not take any medications.  Which of the following will be helpful for diagnosis at this time? A  Detailed history and physical examination B  Chest x-ray C  Blood workup including CBC, CMP, NT proBNP D  12-lead ECG E All of the above   Answer #4   The correct answer is E – All of the above.  Mr. Stevens presents with signs and symptoms of volume overload concerning for new onset heart failure. The history and physical exam remain the cornerstone in the assessment of patients with HF. Not only is the H&P valuable for identifying the presence of heart failure but also may provide hints about the degree of congestion, underlying etiology, and alternative diagnoses. As such H&P earns a Class 1 indication for a variety of reasons in patients with heart failure: 1.       Vital signs and evidence of clinical congestion should be assessed at each encounter to guide overall management, including adjustment of diuretics and other medications (Class 1, LOE B-NR) 2.       Clinical factors indicating the presence of advanced HF should be sought via the history and physical examination (Class 1, LOE B-NR) 3.       A 3-generation family history should be obtained or updated when assessing the cause of the cardiomyopathy to identify possible inherited disease (Class 1, LOE B-NR) 4.       A thorough history and physical examination should direct diagnostic strategies to uncover specific causes that may warrant disease-specific management (Class 1, LOE B-NR) 5.       A thorough history and physical examination should be obtained and performed to identify cardiac and noncardiac disorders, lifestyle and behavioral factors, and social determinants of health that might cause or accelerate the development or progression of HF (Class 1, LOE C-EO) Building on the H&P, laboratory evaluation provides important information about comorbidities, suitability for and adverse effects of treatments, potential causes or confounders of HF, severity and prognosis of HF, and more. As such, 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, LOE C-EO). In addition, the specific cause of HF should be explored using additional laboratory testi...

Question #3 Which of the following is/are true about heart failure epidemiology? A Although the absolute number of patients with HF has partly grown, the incidence of HF has decreased B Non-Hispanic Black patients have the highest death rate per capita resulting from HF C In patients with established HF, non-Hispanic Black patients have a higher HF hospitalization rate compared with non-Hispanic White patients D In patients with established HF, non-Hispanic Black patients have a lower death rate compared with non-Hispanic White patients E All of the above Answer #3 Explanation    The correct answer is “E – all of the above.”   Although the absolute number of patients with HF has partly grown as a result of the increasing number of older adults, the incidence of HF has decreased. There is decreasing incidence of HFrEF and increasing incidence of HFpEF. The health and socioeconomic burden of HF is growing. Beginning in 2012, the age-adjusted death-rate per capita for HF increased for the first time in the US. HF hospitalizations have also been increasing in the US. In 2017, there were 1.2 million HF hospitalizations in the US among 924,000 patients with HF, a 26% increase compared with 2013.   Non-Hispanic Black patients have the highest death rate per capita. A report examining the US population found the age-adjusted mortality rate for HF to be 92 per 100,000 individuals for non-Hispanic Black patients, 87 per 100,000 for non-Hispanic White patients, and 53 per 100,000 for Hispanic patients.   Among patients with established HF, non-Hispanic Black patients experienced a higher rate of HF hospitalization and a lower rate of death than non-Hispanic White patients with HF.Hispanic patients with HF have been found to have similar or higher HF hospitalization rates and similar or lower mortality rates compared with non-Hispanic White patients. Asian/Pacific Islander patients with HF have had a similar rate of hospitalization as non-Hispanic White patients but a lower death rate.   These racial and ethnic disparities warrant studies and health policy changes to address health inequity. Main Takeaway Racial and ethnic disparities in death resulting from HF persist, with non-Hispanic Black patients having the highest death rate per capita, and a higher rate of HF hospitalization. Further clinical studies and health policy changes are needed to address ...

Question #2 A 67-year-old man with a past medical history of type 2 diabetes mellitus, hypertension, and active tobacco smoking presents to the emergency room with substernal chest pain for the past 5 hours. An electrocardiogram reveals ST segment elevations in the anterior precordial leads and he is transferred emergently to the catheterization laboratory. Coronary angiography reveals 100% occlusion of the proximal left anterior descending artery, and he is successfully treated with a drug eluting stent resulting in TIMI 3 coronary flow. Following his procedure, a transthoracic echocardiogram is performed which reveals a left ventricular ejection fraction of 35% with a hypokinetic anterior wall. Which of the following medications would be the best choice to prevent the incidence of heart failure and reduce mortality? A Lisinopril B Diltiazem C Carvedilol D Sacubitril-valsartan E Both A and C Answer #2 The correct answer is E – both lisinopril and carvedilol are appropriate to reduce the incidence of heart failure and mortality. Evidence-based beta-blockers and ACE inhibitors both have Class 1 recommendations in patients with a recent myocardial infarction and left ventricular ejection fraction ≤ 40% to reduce the incidence of heart failure and to reduce mortality. Multiple randomized controlled trials have investigated both medications in the post myocardial infarction setting and demonstrated improved ventricular remodeling as well as benefits for mortality and development of incident heart failure. At this time, there is not sufficient evidence to recommend ARNi over ACEi for patients with reduced LVEF following acute MI. The PARADISE-MI trial randomized a total of 5,661 patients with myocardial infarction complicated by a reduced LVEF, pulmonary congestion, or both to receive either sacubitril-valsartan (97-103mg twice daily) or ramipril (5mg twice daily). After a median follow up time of 22 months, there was no statistically significant difference in the primary outcome of cardiovascular death or incident heart failure. At this time, ARNi have not been included in the guidelines for this specific population. Diltiazem is a non-dihydropyridine calcium channel blocker, a family of drugs with negative inotropic effects and which may be harmful in patients with depressed LVEF (Class 3: Harm, LOE C-LD). Main Takeaway:  For patients with recent myocardial infarction and reduced left ventricular function both beta blockers and ACEi have Class 1 recommendations to reduce the incidence of heart failure and decrease mortality.

Question #1 A 23-year-old man presents to his primary care physician for an annual visit. His father was diagnosed with idiopathic cardiomyopathy at 40 years of age. His blood pressure in clinic is 146/90 mmHg. He is a personal trainer and exercises daily, including both weightlifting and cardio. He denies any anabolic steroid use. He is an active tobacco smoker, approximately ½ pack per day. Review of systems is negative for symptoms. What stage of heart failure most appropriately describes his current status? A Stage A B Stage B C Stage C D Stage D E None of the above Answer #1 The correct answer is A – Stage A of heart failure. Overall, the ACC/AHA stages of HF were designed to emphasize the development and progression of disease. More advanced stages and progression are associated with reduced survival. Stage A HF is where patients are “at risk for HF”, but without current or previous symptoms or signs of HF, and without structural/functional heart disease or abnormal biomarkers. At-risk patients include those with hypertension, cardiovascular disease, diabetes, obesity, exposure to cardiotoxic agents, genetic variant for cardiomyopathy, or family history of cardiomyopathy. Stage B HF is the “pre-heart failure” stage where patients are without current or previous symptoms or signs of HF but do have at least one of the following: Structural heart disease (i.e., reduced left or right ventricular systolic function, ventricular hypertrophy, chamber enlargement, wall motion abnormalities, and valvular heart disease) Evidence of increased filling pressures Risk factors and increased natriuretic peptide levels or persistently elevated cardiac troponin in the absence of an alternate diagnosis Stage C HF indicates symptomatic heart failure where patients have current or previous symptoms or signs of HF. Stage D HF indicates advanced heart failure with marked HF symptoms that interfere with daily life and with recurrent hospitalizations despite attempts to optimize guideline-directed medical therapy. Therapeutic interventions in each stage aim to modify risk factors (Stage A), treat risk and structural heart disease to prevent HF (stage B), and reduce symptoms, morbidity, and mortality (stages C and D). Given this patient’s family and social histories, along with the clinical finding of elevated blood pressure, he is best classified as having Stage A, or at risk for HF.

Pearls and Quotes Cardiac amyloidosis is no longer considered a rare disease, especially transthyretin amyloidosis in older male patients with HFpEF and aortic stenosis. Echocardiogram is the “gate keeper” of cardiac imaging and provides initial evidence of amyloid infiltration, while cardiac MRI can help refine the presence of an infiltrative cardiomyopathy versus other causes of increased wall thickness. The most clinically important types of amyloid heart disease are transthyretin (ATTR) and light chain (AL) amyloidosis. The workup to differentiate these disorders includes a gammopathy panel to screen for the presence of potentially amyloidogenic light chains (serum and urine electrophoresis WITH immunofixation and serum free light chains), and cardiac scintigraphy with Technetium-99m-labeled bone-seeking tracers (PYP, DPD, etc.) to identify cardiac aTTR infiltration if the gammopathy panel is unrevealing. There is still a role for endomyocardial biopsy in the diagnosis of cardiac amyloidosis! All patients in whom there is concern for cardiac amyloidosis and gammopathy panel indicates the presence of monoclonal light chains should have a biopsy to obtain a tissue diagnosis of likely AL amyloidosis. Alternatively, an endocardial biopsy may prove valuable in patients who have confusing phenotypic features between amyloid types, such as a patient with abnormal monoclonal protein and positive PYP imaging. Be suspicious of heart failure patients that do not tolerate typical medications that lower heart rate. In the restrictive cardiomyopathy of cardiac amyloidosis, patients are reliant on higher heart rates to compensate for the inability to augment stroke volume. Be suspicious of amyloidosis in patients with recurrent left atrial thrombi despite anticoagulation. Show notes CardioNerds Cardiac Amyloid, updated 1.20.21 1. What is cardiac amyloidosis and how common is it? Cardiac amyloidosis is adisorder caused by misfolding of proteins into insoluble forms which are deposited into extracellular spaces of the heart, commonly causing a stiff and thick heart with progressive diastolic dysfunction with restrictive hemodynamics and ensuing heart failure. The two most common types of amyloid protein that affect the heart are transthyretin (ATTR) and light chain (AL).

This episode is focused on Palliative Care and Shared Decision-Making in the CICU. In this episode, we learn about how the principles of palliative care and shared decision-making apply to our patients across the spectrum of cardiovascular care, especially in the cardiac intensive care unit. We discuss pivotal trials of specialty palliative care and decision aids in cardiology and how they might inform our practice to enhance patient quality of life and improve goal-concordant care. Finally, we discuss practical tips and communication strategies for how to engage patients about end-of-life decisions and topics that can be utilized from outpatient to inpatient to critical care settings. “We need to help patients hope for the best and plan for the worst as time goes on.” Dr. Larry Allen Series co-chairs Dr. Eunice Dugan and Dr. Karan Desai, along with CardioNerds Co-founder Amit Goyal are joined by FIT lead, Dr. Sarah Chuzi.

Pearls and Quotes - Palliative Care and Shared Decision-Making in the CICU 1. “Much of what we do in cardiology is thinking about how to make people feel better (not just improving cardiac function or length of life). So, on a day-to-day basis we are really providing primary palliative care.” – Dr. Larry Allen 2. “Risk models in cardiology can only be so accurate… While risk models can give us some grounding, we also need to embrace the concept of uncertainty, and help patients understand that there are a variety of things that might happen to them, suggest some things they might plan for, and continue to iteratively come back to the patient and reevaluate what their options are.” – Dr. Larry Allen 3. “Our goal is to help people live happy, healthy, full lives. But, everyone dies. So understanding that death is a part of life and understanding how to help them make those transitions is critical” – Dr. Larry Allen 4. “Having good deaths is a part of good healthcare. We can’t ignore that. We can’t fight against it. We should embrace it. And we have the opportunity to do that.” – Dr. Larry Allen 5. We should still keep in mind the concept of medical futility and determining what options are reasonable for patients. Part of shared decision-making includes discussing what interventions would not be feasible or helpful with patients and families Show notes - Palliative Care and Shared Decision-Making in the CICU Notes drafted by Dr. Sarah Chuzi. 1. How are the basic principles of palliative care relevant to cardiology, and can you define the key concepts of shared decision-making, primary palliative care, specialty (or secondary) palliative care, and hospice care? Throughout medicine, we confront the concepts of symptom control, difficult medical decision-making, and end-of-life. These are the principles of palliative care and they apply very easily across the spec...

Partial anomalous pulmonary venous return refers to anomalies in which one or more (but not all) of the pulmonary veins connects to a location other than the left atrium. This causes left to right shunting which may have hemodynamic and therefore clinical significance, warranting repair in some patients.

Pearls - Partial Anomalous Pulmonary Venous Return (PAPVR) What is partial anomalous pulmonary venous return (PAPVR)? PAPVR refers to anomalies in which one or more (but not all) of the pulmonary veins connects to a location other than the left atrium. Often, this means one or more pulmonary veins empty into the right atrium or a systemic vein such as the superior vena cava or inferior vena cava. Physiologically, this produces a left-to-right shunt, allowing for already-oxygenated blood to recirculate into the lungs and result in excessive pulmonary blood flow.  What are the clinical features of PAPVR?Diagnosis is usually incidental on a cross sectional imaging such as CTA or CMR.The most common associated lesion is an atrial-level defect.It is unusual for a single anomalous pulmonary venous connection of only 1 pulmonary lobe to result in significant shunting. Patients with a significant degree of left to right shunting may have right heart dilatation or symptoms of dyspnea on exertion. When are some strategies for managing patients with PAPVR?A surgical correction is recommended for patients with PAPVR when functional capacity is impaired and RV enlargement is present, there is a net left-to-right shunt sufficiently large to cause physiological sequelae (aka: ratio of pulmonary flow (Qp) to systemic flow (Qs) is > 1.5:1), PA systolic pressure is less than 50% systemic pressure and pulmonary venous resistance is less than one third of systemic venous resistance.Surgical repair involves intracaval baffling of the left atrium (Warden procedure) or direct reimplantation of the anomalous pulmonary vein into the left atrium.Pregnancy is well tolerated in patients with repaired PAPVR. In patients with unrepaired lesion who may have right sided heart dilatation and/or pulmonary hypertension, preconception evaluation and counseling should address how pregnancy may affect mother’s and fetus’s health. Antibiotic prophylaxis for infective endocarditis is typically not needed unless patients are less than 6 months from recent surgery, have residual defect at the patch margin or prior history of infective endocarditi...
