I50.2

Clinical Causes: Coronary artery disease (blockages in the blood vessels supplying the heart) Previous heart attack (myocardial infarction) High blood pressure (hypertension) that overworks the heart Cardiomyopathy (disease of the heart muscle) Heart valve diseases that strain the heart Chronic alcohol abuse or drug toxicity Viral infections affecting the heart (myocarditis)

Key Symptoms: Shortness of breath, especially during exertion or when lying flat Fatigue and weakness Swelling in the legs, ankles, and feet (edema) Rapid or irregular heartbeat (palpitations) Persistent cough or wheezing, sometimes with pink, blood-tinged sputum Lack of appetite and nausea Sudden weight gain due to fluid retention Reduced ability to exercise or perform daily activities

Diagnosis Path: Diagnosis of systolic heart failure involves a combination of medical history, physical examination, and diagnostic tests. Common procedures include: - Echocardiogram: A key test that uses ultrasound to assess the heart's pumping strength and structure. - Chest X-ray: To visualize the size of the heart and presence of fluid in the lungs. - Electrocardiogram (ECG): To detect abnormal heart rhythms. - Blood tests: Including B-type natriuretic peptide (BNP) levels, which are elevated in heart failure. - Cardiac MRI or stress tests may also be employed to evaluate heart function in detail.

Treatment Protocols: While it's not possible to cure systolic heart failure, various treatments aim to manage symptoms and improve quality of life: - Medications: - ACE inhibitors and ARBs to relax blood vessels and reduce heart workload. - Beta-blockers to slow heart rate and decrease blood pressure. - Diuretics to reduce fluid buildup. - Aldosterone antagonists for additional fluid control. - Digoxin in specific cases to improve heart strength. - Lifestyle modifications: - Dietary changes such as sodium restriction. - Regular, moderate exercise as recommended by a healthcare provider. - Quitting smoking and limiting alcohol intake. - Devices and surgical options: - Implantable devices like defibrillators or pacemakers. - Surgical procedures such as valve repair or replacement, coronary bypass surgery, or heart transplantation in severe cases. - Ongoing medical care and monitoring are essential for managing the condition effectively.
