Abstract

We assessed the prognostic value of the platelet to lymphocyte ratio (PLR) on in-hospital and long-term major adverse cardiovascular events (MACEs) in patients with ST-segment elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (pPCI) in a large prospective study. Patients (n = 1938) admitted with acute STEMI within 12 hours of symptom onset and who underwent pPCI between January 2010 and January 2015 were followed up for 31.6 ± 16.2 months. During the in-hospital and long-term follow-up period, MACE, the prevalence of stent thrombosis, nonfatal myocardial infarction, and mortality were higher in the third PLR tertile group. A PLR in the third tertile had 2.4-fold increased risk of in-hospital MACE and 2.8-fold risk of long-term MACE. The PLR was significantly and positively correlated with peak creatine kinase MB (CK-MB) levels (r = 0.562, P < .001) and Gensini score (r = 0.408, P < .001). Kaplan-Meier analysis of long-term MACE-free survival revealed a higher occurrence of MACE in the third PLR tertile group compared to the other tertiles. In conclusion, the PLR may be a marker of inflammatory and prothrombotic status and predicted in-hospital and long-term MACE in a population with STEMI.
