Heart Failure Care for Seniors

Heart failure (HF) is a chronic condition in which the heart cannot pump enough blood to meet the body's needs. It is NOT the heart 'stopping' — it means the heart is working inefficiently. Causes include: coronary artery disease (most common), prior heart attack, hypertension, diabetes, obesity, atrial fibrillation, cardiomyopathy, and valvular heart disease. There are two types: HFrEF (heart failure with reduced ejection fraction, EF < 40%) where the heart muscle is weak; and HFpEF (preserved EF, ≥ 50%) where the heart is stiff and doesn't fill properly. HFpEF is more common in older women and is harder to treat.

Warning signs that heart failure is worsening (decompensating): sudden weight gain of 2–3 lbs in 24 hours or 5 lbs in a week (fluid retention), increasing shortness of breath, new or worsening leg or ankle swelling, needing extra pillows to sleep (orthopnea), awakening at night with breathlessness (paroxysmal nocturnal dyspnea), persistent cough or wheezing, fatigue with minimal activity, confusion or lightheadedness. Have a written action plan — call the cardiologist if any of these occur before waiting for the next appointment.

The standard sodium recommendation for heart failure is 2,000 mg/day (2 grams). Some guidelines allow up to 2,300 mg/day for milder cases. Excess sodium causes water retention, which worsens fluid overload — the primary cause of HF hospitalizations. Common high-sodium foods: canned soups (800–1,400 mg/serving), deli meats, frozen meals, restaurant food, pickles, soy sauce, and processed snacks. Teaching seniors to read food labels and cook at home is the most impactful dietary intervention for HF management.

Medicare covers most heart failure care: Part B covers cardiology visits, echocardiograms, stress tests, and cardiac catheterization. Medicare covers cardiac rehabilitation (up to 36 sessions; 72 with medical necessity documentation) for patients with qualifying cardiac conditions including recent heart failure hospitalization. Part A covers hospitalizations and up to 100 days of skilled nursing after a 3-day hospital stay. Part D covers heart failure medications. What Medicare does NOT cover: long-term assisted living or nursing home room and board. Medicaid covers nursing home care for eligible low-income seniors.

Assisted living becomes appropriate when: NYHA Class III symptoms make home management unsafe (frequent falls, missed medications, inability to weigh daily or manage sodium), the caregiver is at risk of burnout, there are frequent HF hospitalizations that better care coordination could prevent, or the person lives alone and needs 24-hour supervision for safety. Key assisted living benefits for HF patients: medication management (critical for complex multi-drug regimens), daily weight monitoring, low-sodium meal planning, and 24-hour staff to recognize worsening symptoms.

A Left Ventricular Assist Device (LVAD) is a mechanical heart pump implanted surgically into the chest to assist the left ventricle in pumping blood. LVADs are used as: bridge to transplant (keeping patients alive while waiting for a donor heart) or destination therapy (permanent implant for patients who are not transplant candidates). LVADs are for patients with advanced HFrEF (NYHA Class III–IV, EF < 25%) on optimal medical therapy who remain severely symptomatic. They improve survival and quality of life but require significant ongoing care, carry risks of stroke and infection, and require a caregiver trained in LVAD management.

HFrEF (Heart Failure with Reduced Ejection Fraction) — EF < 40%: the heart muscle is weak and can't pump enough blood. More common in men; caused by heart attacks, cardiomyopathy. Has well-established medications (ACEi/ARB/ARNi + beta-blocker + MRA + SGLT2i) that reduce mortality. HFpEF (Heart Failure with Preserved Ejection Fraction) — EF ≥ 50%: the heart muscle is stiff and doesn't relax/fill properly. More common in older women with hypertension, obesity, and diabetes. Until recently had no proven mortality-reducing therapy — now SGLT2 inhibitors (dapagliflozin, empagliflozin) and spironolactone in select patients show benefit. Both types benefit equally from sodium restriction, fluid management, and exercise.

Cardiac rehabilitation is a supervised program of exercise, education, and counseling for people with heart conditions. For heart failure, it reduces hospitalizations, improves exercise capacity, and improves quality of life. Medicare Part B covers cardiac rehab for patients who have had a qualifying event (MI, coronary bypass, heart valve repair/replacement, or stable angina) — up to 36 sessions, with an additional 36 possible with medical necessity documentation. Note: heart failure alone (without a qualifying cardiac event) is NOT a Medicare-qualifying indication for cardiac rehab, though this may change. Some Medicare Advantage plans have broader coverage — check your specific plan.
