Get Heart Failure Treatment Online

Heart failure is a chronic condition in which the heart cannot pump enough blood to meet the body's needs. A heart attack occurs when blood flow to part of the heart muscle is suddenly blocked. Heart failure often develops gradually over time and may be caused by a prior heart attack, high blood pressure, or other conditions.

Common symptoms include shortness of breath (especially when lying flat or during activity), swelling in the legs, ankles, or feet, persistent fatigue, rapid or irregular heartbeat, and unexplained weight gain due to fluid retention.

Ejection fraction (EF) is the percentage of blood the heart pumps out with each beat. A normal EF is 50% or higher. Heart failure with reduced ejection fraction (HFrEF) means the heart muscle is weakened; heart failure with preserved ejection fraction (HFpEF) means the muscle is stiff. The type of heart failure affects which treatments are most appropriate.

Heart failure currently has no cure for most patients, but it can be effectively managed. With guideline-directed medications, lifestyle changes such as fluid and sodium restriction, and regular monitoring, many people with heart failure can significantly improve their symptoms and reduce the risk of hospitalization.

Current guidelines recommend four cornerstone medication classes for heart failure with reduced ejection fraction: ARNI therapy (such as sacubitril-valsartan), beta-blockers (such as carvedilol or metoprolol), mineralocorticoid receptor antagonists (such as spironolactone), and SGLT2 inhibitors (such as dapagliflozin or empagliflozin). A physician will determine which options are appropriate based on your specific type of heart failure and other health conditions.

Key lifestyle measures include restricting daily sodium intake (typically under 2,000 mg), monitoring daily weight to catch fluid buildup early, limiting fluid intake if recommended by your doctor, avoiding alcohol and tobacco, staying as physically active as safely tolerated, and attending all follow-up appointments.
