Abstract:
BACKGROUND:Chronic total occlusion (CTO) in a noninfarct-related artery (non-IRA) is an independent predictor of mortality in non-ST elevation myocardial infarction (NSTEMI). Mean platelet volume (MPV) is associated with cardiovascular events in NSTEMI. Little is known about the predictors of non-IRA-CTO in patients with NSTEMI. The purpose of this study was to evaluate the relationship between the presence of non-IRA-CTO with MPV level in patients with NSTEMI and multivessel coronary artery disease (MVCAD). METHODS:Data of consecutive patients with NSTEMI and MVCAD treated in high-volume PCI center between 2006 and 2012 and included in the prospective registry were divided according to the presence of CTO and analyzed. RESULTS:In the group of 685 patients fulfilling the inclusion criteria, 308 (45%) patients had CTO (CTO+), and in 377 (55%) patients CTO was not observed (CTO-). The MPV level on admission was significantly higher in the CTO+ group than in the CTO- group (P<0.0001). In the multivariate analysis of the entire study population, independent predictors of occurrence of CTO were medium platelet volume (MPV; per 1fL more; odds ratio [OR] 1.34; 95% confidence interval [CI] 1.15-1.57; P=0.0002) together with left ventricular ejection fraction and prior MI. CONCLUSIONS:MPV at admission is independently associated with more frequent occurrence of non-IRA CTO in patients with NSTEMI and MVCAD.
