I50.810

Clinical Causes: Chronic lung diseases such as COPD or pulmonary fibrosis, leading to increased pressure in the pulmonary arteries (cor pulmonale) Left-sided heart failure, which can increase stress on the right ventricle Pulmonary hypertension (high blood pressure in pulmonary arteries) Congenital heart defects affecting right heart function Right ventricular infarction (heart attack in the right ventricle) Valvular heart diseases impacting the tricuspid or pulmonary valves Pericardial diseases such as constrictive pericarditis Other conditions that strain the right side of the heart

Key Symptoms: Swelling (edema) in the legs, ankles, and abdomen (ascites) Shortness of breath, especially during exertion or lying flat Fatigue and weakness Rapid or irregular heartbeat Palpitations Weight gain due to fluid retention Liver congestion causing discomfort or tenderness in the upper right abdomen Decreased ability to exercise or perform daily activities Frequent urination at night

Diagnosis Path: Echocardiogram (ultrasound of the heart) to evaluate heart function and valve status Chest X-ray to check for heart size and lung congestion Electrocardiogram (ECG) to detect arrhythmias or signs of heart strain Blood tests to assess organ function and identify underlying causes Right heart catheterization to measure pressures inside the heart and lungs Other imaging studies such as MRI or CT scans if needed

Treatment Protocols: Medications such as diuretics to reduce fluid buildup Vasodilators to decrease pulmonary blood pressure ACE inhibitors or angiotensin receptor blockers to improve heart function Adjustments in lifestyle, including salt restriction and weight management Treating underlying lung or heart conditions contributing to failure Monitoring and managing arrhythmias if present Surgical interventions or procedures in severe cases, such as valve repair or replacement Regular follow-up with healthcare providers to monitor disease progression
