This study aimed to determine the relationship between the diameter of coronary artery stents and age, gender, diabetes mellitus (DM), left ventricular ejection fraction (LVEF), renal dysfunction, and the clinical presentation of myocardial ischemia in the cohort of patients with implanted stents in coronary arteries with severe stenotic lesions. This study included 2256 patients (mean age, 59.3±10.9 years; men, 62%) who underwent percutaneous coronary intervention (PCI). The clinical status of the patients at presentation was subcategorized as follows: ST-segment elevation myocardial infarction, non-ST segment elevation myocardial infarction, unstable angina pectoris, and stable angina pectoris. The diameters, without any type or brand differentiation, were divided into two groups as follows: Group I, which included 2.5- and 2.75-mm-diameter stents, and Group II, which included ≥3-mm-diameter stents. The type of procedure, including primary PCI, early invasive strategy, and elective stenting, was not found to be a significant factor affecting the diameter of coronary artery stents. Univariate and multivariate analyses revealed a relationship between the diameter of coronary artery stents and age, gender, DM, and LVEF. This study demonstrated that the diameter of coronary artery stents was independently associated with gender, age, a history of DM, and moderate-to-severe systolic left ventricular dysfunction.
