Heart Failure & Pulmonary Edema
Differentiate chronic and acutely decompensated heart failure and choose evidence-based stabilization and long-term management.
Module format: each study session covers what to learn, how the presentation appears clinically, investigation/management priorities, safety issues and common MCCQE traps.
Module 3 — Topic map
- HFrEF, HFmrEF and HFpEF: clinical presentation and common causes
- Left- versus right-sided heart failure and signs of systemic/pulmonary congestion
- Evaluation with ECG, chest radiograph, laboratory testing, natriuretic peptides and echocardiography
- Acute decompensated heart failure and acute pulmonary edema
- Guideline-directed chronic HFrEF pharmacotherapy: foundational drug classes and titration principles
- Diuretics, volume status, monitoring electrolytes/renal function and recognizing over-diuresis
- Device therapy concepts: ICD and CRT selection principles
- Precipitating causes of decompensation: ischemia, arrhythmia, infection, medication/nonadherence and uncontrolled hypertension
- Advanced/end-stage heart failure, referral, goals of care and palliative symptom management

Study Session 3.1 — Heart Failure Diagnosis: HFrEF, HFpEF & Causes
Focused MCCQE cardiovascular study session
Core topics & learning goals
- Recognize left- and right-sided HF symptoms/signs.
- Differentiate HFrEF, HFmrEF and HFpEF conceptually using LVEF and clinical setting.
- Identify ischemic, valvular, hypertensive, arrhythmic, toxic, inflammatory and cardiomyopathic causes.
- Use ECG, CXR, labs, natriuretic peptides and echocardiography appropriately.
Clinical recognition & investigation
- Assess congestion, perfusion, weight change and functional status.
- Identify mimics such as COPD, nephrotic/renal disease, anemia and venous insufficiency.
Management & patient-safety priorities
- Treat the cause and establish chronic guideline-directed therapy when appropriate.
- Educate about daily weights, adherence and warning symptoms.
MCCQE exam traps
- Normal natriuretic peptide values are more useful for ruling out HF in the right context than for defining etiology.
- Peripheral edema alone is nonspecific.
Study Session 3.2 — Acute Decompensated HF & Pulmonary Edema
Focused MCCQE cardiovascular study session
Core topics & learning goals
- Recognize acute pulmonary edema, severe congestion and low-output states.
- Identify precipitants: ischemia, arrhythmia, infection, uncontrolled BP, renal dysfunction and nonadherence.
- Use oxygen/ventilatory support, IV diuresis and vasodilator strategy according to physiology.
- Recognize cardiogenic shock and need for urgent specialist/invasive management.
Clinical recognition & investigation
- Differentiate warm/wet, cold/wet and other hemodynamic profiles conceptually.
- Monitor renal function, electrolytes, urine output and response to therapy.
Management & patient-safety priorities
- Stabilize airway/breathing/circulation first.
- Avoid routine fluid boluses in a clearly volume-overloaded pulmonary edema patient.
MCCQE exam traps
- Worsening creatinine during decongestion needs context; do not stop effective therapy reflexively without assessing perfusion/volume.
- Beta-blocker initiation/up-titration is not the first move in unstable shock.
Study Session 3.3 — Chronic HFrEF Therapy, Devices & Advanced Care
Focused MCCQE cardiovascular study session
Core topics & learning goals
- Know foundational HFrEF medication classes: ARNI/ACEi/ARB, evidence-based beta blocker, MRA and SGLT2 inhibitor.
- Use loop diuretics for congestion and understand monitoring needs.
- Recognize common contraindications/adverse effects including hyperkalemia, renal dysfunction and hypotension.
- Understand ICD/CRT concepts, specialist referral and advanced HF features.
- Address vaccination, exercise/cardiac rehab, sodium/fluid advice when appropriate and comorbidity control.
Clinical recognition & investigation
- Reassess volume, BP, renal function, potassium, adherence and symptoms during titration.
- Integrate goals of care and palliative symptom management in advanced disease.
Management & patient-safety priorities
- Optimize disease-modifying therapy after stabilization.
- Refer for device/advanced-therapy assessment when indicated.
MCCQE exam traps
- Diuretics improve congestion but are not the main mortality-reducing foundation.
- Avoid NSAIDs and other agents that can worsen HF when alternatives exist.
