Hypertrophic Cardiomyopathy

Hypertrophic cardiomyopathy is an inherited myocardial disease characterized by unexplained left ventricular hypertrophy, impaired diastolic filling, and sometimes dynamic left ventricular outflow tract obstruction. In this episode, Chris and Mars review: * The classic genetics and asymmetric septal hypertrophy of HCM * Systolic anterior motion of the mitral valve * Why the murmur gets louder with standing and Valsalva * Exertional dyspnea, angina, syncope, and sudden cardiac death * Echocardiography and cardiac M R I findings * Beta blockers as first-line treatment for symptomatic obstructive HCM * Medications and volume changes that can worsen outflow obstruction * Sudden-death risk assessment and implantable cardioverter-defibrillator indications * Atrial fibrillation, anticoagulation, exercise, genetics, and family screening Episode pearl: In obstructive HCM, a smaller left ventricular cavity means more obstruction—which explains both the murmur maneuvers and many of the treatment decisions.

Dilated Cardiomyopathy

Dilated cardiomyopathy is a major cause of heart failure with reduced ejection fraction characterized by ventricular dilation and impaired contractility. In this episode, Chris and Mars review: * The “big ventricle, weak squeeze” physiology of dilated cardiomyopathy * Classic causes including alcohol, myocarditis, anthracyclines, genetic disease, peripartum cardiomyopathy, and tachycardia-mediated cardiomyopathy * Key examination and echocardiographic findings * How to distinguish dilated cardiomyopathy from ischemic, valvular, hypertrophic, and restrictive disease * The role of cardiac M R I and genetic evaluation * The four foundational medications for HFrEF * Why reversible causes must be identified early * Ventricular arrhythmias, sudden cardiac death, and left ventricular mural thrombus * Why first-degree relatives may need cardiac and genetic screening Episode pearl: A dilated, poorly contracting ventricle gives you the diagnosis pattern—but the next question should always be: why did it become dilated?

Cardiogenic Shock

Cardiogenic shock is a life-threatening state of inadequate tissue perfusion caused by severe cardiac dysfunction. The key is to recognize low-output physiology, support perfusion, and rapidly identify the underlying cause. In this episode, Chris and Mars review: The classic hemodynamic pattern of cardiogenic shock How to distinguish cardiogenic shock from septic, hypovolemic, and obstructive shock Why cool extremities, elevated jugular venous pressure, pulmonary edema, oliguria, and rising lactate matter Norepinephrine as the preferred first-line vasopressor for hypotensive cardiogenic shock When to add an inotrope such as dobutamine or milrinone Why large fluid boluses can worsen left-sided cardiogenic shock Myocardial infarction as a major cause and the importance of emergency reperfusion Post-MI mechanical complications including papillary muscle rupture, ventricular septal rupture, and free wall rupture When persistent shock should prompt invasive hemodynamic assessment and consideration of temporary mechanical circulatory support Episode pearl: Support the pressure with norepinephrine, support cardiac output with an inotrope when needed, and always treat the cause of the shock.

Heart Failure With Preserved Ejection Fraction

Heart failure with preserved ejection fraction, or HFpEF, is a form of heart failure caused primarily by impaired ventricular relaxation and reduced left ventricular compliance despite a preserved ejection fraction. In this episode, Chris and Mars review: Why a normal ejection fraction does not mean normal cardiac function The classic HFpEF patient: older adults with hypertension, obesity, diabetes, chronic kidney disease, or atrial fibrillation The role of concentric left ventricular hypertrophy and diastolic dysfunction Classic symptoms and physical exam findings, including the S four How HFpEF is diagnosed using clinical heart failure plus evidence of elevated filling pressures or diastolic dysfunction Why obesity can lower B N P levels S G L T two inhibitors as foundational therapy Loop diuretics for congestion and the importance of blood pressure control Why HFpEF treatment should not simply copy the HFrEF medication regimen Management of associated conditions including atrial fibrillation, obesity, kidney disease, coronary disease, and sleep apnea Episode pearl: Preserved ejection fraction does not mean preserved cardiac function. HFpEF is a filling-pressure problem caused by a stiff, poorly relaxing ventricle. Medicine Shelf Prep is sponsored by Scrub Battle.

Acute Decompensated Heart Failure

Acute decompensated heart failure is a high-yield medicine shelf emergency where management depends on two key questions: Is the patient congested, and is the patient adequately perfusing? In this episode, Chris and Mars review: Classic signs of pulmonary and systemic congestion Intravenous loop diuretics for volume overload Nitrates and noninvasive positive pressure ventilation in hypertensive pulmonary edema How to recognize cardiogenic shock Why norepinephrine is the preferred first-line vasopressor in hypotensive cardiogenic shock When to add an inotrope such as dobutamine or milrinone Cardiorenal syndrome and why a rising creatinine does not always mean diuresis should stop Common triggers for acute heart failure decompensation Episode pearl: Congested but perfusing? Decongest. Hypotensive with end-organ hypoperfusion? Think cardiogenic shock. Medicine Shelf Prep is sponsored by Scrub Battle.

ST-Elevation Myocardial Infarction

ST-elevation myocardial infarction, or STEMI, is an acute coronary emergency caused by coronary plaque rupture and thrombotic occlusion leading to transmural myocardial ischemia. The key is rapid recognition and immediate reperfusion. In this episode, Chris and Mars review: Classic STEMI presentation and important atypical symptoms How to localize infarction using the E C G Why treatment should not wait for troponin or echocardiography Emergency reperfusion with percutaneous coronary intervention When fibrinolytic therapy may be considered Antiplatelet therapy, anticoagulation, statins, and nitroglycerin Recognition and management of right ventricular infarction Why nitrates can be dangerous in preload-dependent right ventricular infarction Major post-MI complications, including ventricular arrhythmias, papillary muscle rupture, interventricular septal rupture, and left ventricular free wall rupture Episode pearl: In a clear STEMI, do not let additional testing delay reperfusion. Opening the occluded coronary artery is the priority. Medicine Shelf Prep is sponsored by Scrub Battle.

Chronic Heart Failure With Reduced Ejection Fraction

Chronic heart failure with reduced ejection fraction, or HFrEF, is a form of systolic heart failure caused by impaired left ventricular contractility and an ejection fraction of 40% or less. In this episode, we review: The classic symptoms and physical exam findings of HFrEF Common causes, including ischemic heart disease and dilated cardiomyopathy The role of echocardiography and BNP The major disease-modifying medications for chronic HFrEF Why loop diuretics improve symptoms but not mortality When to consider an ICD or cardiac resynchronization therapy Medicine Shelf Prep is sponsored by Scrub Battle.

Vasospastic Angina

Vasospastic Angina, also called Prinzmetal angina, is caused by transient coronary artery spasm and classically presents with chest pain at rest, often at night or early in the morning. In this episode, we review: The classic presentation of vasospastic angina Why transient ST-segment elevation can occur How to distinguish it from stable angina and acute coronary syndrome The role of coronary angiography and acetylcholine provocation testing First-line treatment with calcium channel blockers Why beta blockers may worsen coronary vasospasm Important triggers including smoking and stimulant use Medicine Shelf Prep is sponsored by Scrub Battle.
