5-Year Clinical Outcomes in the ICTUS (Invasive versus Conservative Treatment in Unstable coronary Syndromes) Trial: A Randomized Comparison of an Early Invasive Versus Selective Invasive Management in Patients With Non–ST-Segment Elevation Acute Coronary

Objectives sent the 5-year clinical outcomes according to treatment strategy with additional risk stratification of the ICTUS (Invasive versus Conservative Treatment in Unstable coronary Syndromes) trial. ound erm outcomes may be relevant to decide treatment strategy for patients presenting with non–ST-segment elevation acute coronary syndromes (NSTE-ACS) and elevated troponin T. s domly assigned 1,200 patients to an early invasive or selective invasive strategy. The outcomes were the composite of death or myocardial infarction (MI) and its individual components. Risk stratification was performed with the FRISC (Fast Revascularization in InStability in Coronary artery disease) risk score. s ear follow-up, revascularization rates were 81% in the early invasive and 60% in the selective invasive group. Cumulative death or MI rates were 22.3% and 18.1%, respectively (hazard ratio [HR]: 1.29, 95% confidence interval [CI]: 1.00 to 1.66, p = 0.053). No difference was observed in mortality (HR: 1.13, 95% CI: 0.80 to 1.60, p = 0.49) or MI (HR: 1.24, 95% CI: 0.90 to 1.70, p = 0.20). After risk stratification, no benefit of an early invasive strategy was observed in reducing death or spontaneous MI in any of the risk groups. sions ients presenting with NSTE-ACS and elevated troponin T, we could not demonstrate a long-term benefit of an early invasive strategy in reducing death or MI.
