摘要
Introduction and objectives: A large proportion of patients with non-ST-segment elevation acute coronary syndrome (NSTEACS) are initially selected for medical management (MM) and do not undergo coronary revascularization during or immediately after the index event. The aim of this study was to explore the clinical pathways leading to MM in NSTEACS patients and their influence on prognosis. Methods: Patient characteristics, pathways leading to MM, and 2-year outcomes were recorded in a prospective cohort of 5591 NSTEACS patients enrolled in 555 hospitals in 20 countries across Europe and Latin America. Cox models were used to assess the impact of hospital management on postdischarge mortality. Results: Medical management was the selected strategy in 2306 (41.2%) patients, of whom 669 (29%) had significant coronary artery disease (CAD), 451 (19.6%) had nonsignificant disease, and 1186 (51.4%) did not undergo coronary angiography. Medically managed patients were older and had higher risk features than revascularized patients. Two-year mortality was higher in medically managed patients than in revascularized patients (11.0% vs 4.4%; P < .001), with higher mortality rates in patients who did not undergo angiography (14.6%) and in those with significant CAD (93%). Risk-adjusted mortality was highest for patients who did not undergo angiography (HR = 1.81; 95%Cl, 1.23-2.65), or were not revascularized in the presence of significant CAD (HR = 1.90; 95%Cl, 1.23-2.95) compared with revascularized patients. Conclusions: Medically managed NSTEACS patients represent a heterogeneous population with distinct risk profiles and outcomes. These differences should be considered when designing future studies in this population. Full English text available from: www.revespcardiol.
