Abstract

Background: No-reflow phenomenon after percutaneous coronary intervention (PCI) in patients with acute ST-segment-elevation myocardial infarction (STEMI) is relatively common and has therapeutic and prognostic implications. Cigarette smoking is known as deleterious in patients with coronary artery disease (CAD), but the effect of smoking on no-reflow phenomenon is less investigated. The aim of this study was to compare no-reflow phenomenon after percutneous coronary intervention for acute myocardial infarction, between smokers and non smokers.

Materials and methods: A total of 141 patients who were admitted to Chamran Hospital (Isfahan, Iran) between March and September, 2012 with a diagnosis of STEMI, enrolled into our Cohort study. Patients were divided into current smoker and nonsmoker groups (based on patient's information). All patients underwent primary PCI or rescue PCI within the first 12-h of chest pain. No-reflow phenomenon, thrombolysis in myocardial infarction (MI) flow, and 24-h complications were assessed in both groups.

Results: A total of 47 current smoker cases (32.9%) and 94 (65.7%) nonsmoker cases were evaluated. Smokers in comparison to nonsmokers were younger (53.47 ± 10.59 vs. 61.46 ± 10.55, P < 0.001) and they were less likely to be hypertensive (15.2% vs. 44.7%, P < 0.001), diabetic (17% vs. 36.2%, P < 0.05), and female gender (4.3% vs. 25.5%, P < 0.01). Angiographic and procedural characteristics of both groups were similar. 9 patients died during the first 24-h after PCI (4.3% of smokers and 6.4% of nonsmokers, P: 0.72). No-reflow phenomenon was observed in 29.8% of current smokers and 31.5% of nonsmokers (P = 0.77).

Conclusion: No-reflow phenomenon or short-term complications were not significantly different between current smokers and non smokers.

Keywords: Cigarette smoking; no-reflow phenomenon; primary percutaneous coronary intervention; thrombolysis in myocardial infarction flow.
