I25.112
Atherosclerotic heart disease of native coronary artery with refractory angina pectoris
Clinical Classification Guidelines
Medical Intelligence & Overview
Atherosclerotic heart disease of the native coronary artery with refractory angina pectoris, classified under ICD-10 code I25.112, is a condition characterized by the buildup of fatty deposits within the coronary arteries. These arteries supply blood to the heart muscle. As deposits accumulate, they can restrict blood flow, leading to persistent chest pain, known as angina. When angina does not respond to standard treatments, it is termed refractory, indicating a more advanced stage of coronary artery disease that requires specialized management.
Causes & Symptoms
Clinical Causes: Progressive accumulation of cholesterol and fatty substances in the coronary arteries Chronic inflammation of arterial walls High levels of LDL cholesterol (bad cholesterol) Low levels of HDL cholesterol (good cholesterol) Lifestyle factors such as smoking, poor diet, and lack of exercise Genetic predisposition to coronary artery disease Hypertension and other risk factors like diabetes mellitus
Key Symptoms: Persistent chest pain or discomfort (angina) Pain radiating to the arms, neck, jaw, shoulder, or back Shortness of breath, especially during exertion Fatigue and weakness Dizziness or lightheadedness during episodes of angina Palpitations or irregular heartbeats
Diagnostic & Treatment
Diagnosis Path: - Coronary angiography as the definitive test, revealing blockages or narrowing in coronary arteries
Treatment Protocols: Medications: - Nitrates for symptom relief - Beta-blockers and calcium channel blockers to decrease heart workload - Antiplatelet agents like aspirin to prevent blood clots - Statins to lower LDL cholesterol levels - Ranolazine for refractory angina management Procedures: - Coronary angioplasty and stenting to open blocked arteries - Coronary artery bypass grafting (CABG) in severe cases Lifestyle modifications: - Heart-healthy diet - Regular physical activity as tolerated - Smoking cessation - Weight management - Control of comorbid conditions such as hypertension and diabetes
