| Popis: | An early invasive strategy is of clinical benefit in moderate and high-risk acute coronary syndromes (ACS). Clinical predictors of short and long-term ischemic outcomes in pts with ACS have been well studied, whereas the extent, location and characteristics of angiographic coronary disease in predicting outcome is not well defined. The ACUITY trial randomized 13,819 pts with moderate and high risk ACS to unfractionated heparin or enoxaparin + GP IIb/IIIa inhibitors (GPI), versus bivalirudin + GPI, vs. bivalirudin alone. The angiographic substudy of ACUITY included the first 7000 consecutive randomized US patients. All angiograms were reviewed by an independent core laboratory for complete 3 vessel assessment of CAD extent and burden (total mm length of lesions>30%DS), as well as baseline and final lesion and flow characteristics. Clinical and angiographic predictors of ischemic outcomes at 30 days and 1 year (death, MI, or ischemic target vessel revascularization) were identified by univariate and multivariable analysis using logistic regression analysis. Of 6921 pts with interpretable angiograms, 3826 pts (55.3%) were treated with PCI, 755 (10.9%) with CABG, and 2340 (33.8%) with medical therapy. Composite ischemia occurred in 595 (8.6%) pts at 30 days and 1153 (17.4%) pts at one year. Independent predictors of 30 day and 1 year ischemic cardiac events by multivariable analysis are shown in the table . Among moderate- to high-risk ACS patients, beyond the well recognized clinical risk factors of renal insufficiency and diabetes mellitus, angiographic manifestations of coronary atherosclerosis including greater burden and severity of disease, and presence of calcified lesions, are important independent predictors of 30 day and 1 year adverse outcomes.
