PurposePlatelets play a key role in the genesis of thrombosis. Plateletcrit (PCT) provides complete information on total platelet mass. The relationship between PCT values and long-term outcomes in patients with ST-segment elevation myocardial infarction (STEMI) who undergo primary angioplasty is not known. We sought to determine the effect of PCT values on the outcomes of primary angioplasty for STEMI.MethodsOverall, 2572 consecutive STEMI patients (mean age, 56.6±11.8 years) undergoing primary percutaneous coronary intervention were enrolled retrospectively into the present study. Plateletcrit at admission was measured as part of the automated complete blood count. Patients were classified into 2 groups: high PCT (>0.237, n=852) and nonhigh PCT (<0.237, n=1720). Clinical characteristics and in-hospital and long-term (median, 21 months) outcomes of primary angioplasty were analyzed.ResultsA higher in-hospital shock rate was observed among patients with high PCT values compared with those with nonhigh PCT values (6.5 vs 3.8%, respectively; P=.003). The long-term cardiovascular prognosis was worse for patients with high PCT values (Kaplan-Meier, log-rank test; P=.007). We used Cox proportional hazard models to examine the association between PCT and adverse clinical outcomes. High PCT values were also an independent predictor of cardiovascular mortality (hazard ratio, 1.85; 95% confidence interval, 1.061-3.22; P=.03).ConclusionHigh PCT values on admission are independently associated with long-term adverse outcomes in patients with STEMI who undergo primary angioplasty.Copyright © 2014 Elsevier Inc.
