I50.42

Clinical Causes: Coronary artery disease High blood pressure (hypertension) Previous heart attacks Cardiomyopathy (diseases of the heart muscle) Heart valve disease Chronic alcohol use or drug abuse Certain infections affecting the heart Arrhythmias (irregular heartbeats) Congenital heart defects

Key Symptoms: Shortness of breath, especially during exertion or when lying down Persistent coughing or wheezing, sometimes producing frothy sputum Swelling in the legs, ankles, feet, or abdomen Fatigue and weakness Rapid or irregular heartbeat Reduced ability to exercise Sudden weight gain due to fluid retention Difficulty concentrating or swelling around the eyes

Diagnosis Path: Echocardiogram (ultrasound of the heart) to assess heart function and structure Electrocardiogram (ECG) to detect irregular heart rhythms Chest X-ray to check for fluid buildup and heart size Blood tests to evaluate kidney function, electrolyte levels, and markers of heart failure Stress tests or cardiac MRI in certain cases Measurement of natriuretic peptides (BNP or NT-proBNP) which are elevated in heart failure

Treatment Protocols: Medications such as ACE inhibitors, beta-blockers, diuretics, and aldosterone antagonists to improve heart function and reduce fluid buildup Lifestyle modifications including low-sodium diet, regular gentle exercise, and weight management Monitoring fluid intake and weight to detect early signs of fluid retention Managing underlying conditions like hypertension, diabetes, or coronary artery disease Device therapies such as implantable defibrillators or biventricular pacemakers in advanced cases In some instances, advanced treatments like heart transplantation or mechanical circulatory support may be considered Patient education on recognizing symptoms and adhering to medication and lifestyle recommendations
