RDW has recently been associated with cardiovascular events and cardiovascular diseases, and it is a novel predictor of mortality. In this study, we aimed to evaluate the clinical usefulness of measuring RDW in patients with coronary stent thrombosis.Patients and methods: We retrospectively reviewed 3,925 consecutive patients who presented with acute coronary syndrome and who underwent coronary angiography at the Siyami Ersek Hospital between May 2011 and December 2013. Of the 3,925 patients, 73 patients (55 males, mean age 59±11 years, 55 with ST elevated myocardial infarction) with stent thrombosis formed group 1. Another 54 consecutive patients who presented with acute coronary syndrome (without coronary stent thrombosis, 22 patients with ST elevated myocardial infarction, 44 males, mean age 54±2 years) and underwent percutaneous coronary intervention in May 2011 formed group 2. Data were collected from all groups for 2 years. The RDW values were calculated from patients 1 month later at follow-up. Syntax scores were calculated for all the patients. The patients were also divided as low syntax score group and moderate–high syntax score group.Results: The patients in group 1 with stent thrombosis had significantly higher RDW level (13.85) than the patients in group 2 without stent thrombosis (12) (P |
