What are the indications for coronary angioplasty in patients of unstable angina?
(Dr. Sudhir Vaishnav) PCI is an effective means of reducing coronary obstruction, improving acute ischemia and improving regional and global left ventricular function in patients with unstable angina. – High risk patients of unstable angina: includes those with prolonged ongoing (>20 minutes) chest pain, pulmonary edema or worsening mitral regurgitation, dynamic ST segment depression of 1 mm or greater, or hypotension. – Patients of unstable angina at intermediate–risk include: angina at rest (>20 minutes) that is relieved with rest or sublingual nitroglycerin, angina associated with dynamic electrocardiographic changes, recent-onset angina with a high likelihood of CAD, pathological Q waves or ST segment depression <1 mm in multiple leads or age older than 65 years. Among patients with borderline LVD (ejection fraction between 40 and 50%) and milder degrees of ischemia, PCI may provide adequate revascularization. Recent data in large trials with drug coated stents suggest that results
