N2 - BACKGROUND: Elderly patients represent one-third of all admissions for non-ST-elevation acute coronary syndrome (NSTEACS) in the coronary care units. Despite their high-risk characteristics and worse outcomes, compared with younger patients, the elderly receive less aggressive treatments, also due to less clear evidence regarding the most effective treatment strategy. PURPOSE: The Italian Elderly ACS study includes patients older than 74 years of age with NSTEACS in a multicenter randomized clinical trial, comparing an early aggressive and an initially conservative approach. Patients not enrolled due to specific exclusion criteria or any other reason will be enrolled in a Registry. CENTERS: Centers with on-site interventional cathlab and centers without on-site cathlab refering patients to a cathlab within a consolidated percutaneous coronary intervention network. PATIENTS: Patients admitted within 48 h of the most recent ischemic symptoms are eligible if they show transient ischemic ECG changes and/or CKMB/Tn elevation. Patients with secondary ischemia, ongoing ischemia, or heart failure, despite optimal therapy or recent coronary intervention, serum creatinine more than 2.5 mg/dl, high bleeding risk, and severe concomitant disease, are excluded from the study. DESIGN: Central randomization to a systematic early aggressive approach (coronary angiography within 48 h of admission and, when indicated, coronary revascularization) or an initially conservative approach (optimal medical therapy with coronary angiography in selected cases with refractory ischemia). Follow-up will include patient visits and ECG at 30 days, 6 months, and 1 year, post randomization. PRIMARY END POINT: The composite of all-cause mortality, myocardial (re)infarction, disabling stroke, and rehospitalization for cardiovascular diseases or severe bleeding within 6 months. SAMPLE SIZE: Expected primary end point rates of 30% in the conservative arm vs. 20% in the invasive arm. According to these estimates, with two-tailed α of 0.05, power will be 80, 85, or 90% with 252, 289, and 338 patients per group, respectively. The goal is to enroll 700 patients from 50 centers.
