- Abstract: BACKGROUND AND OBJECTIVES: Cigarette smoking has been recognized as a prominent threat to women's health. We investigated the impact of smoking on clinical outcomes in Korean female patients after acute myocardial infarction (AMI). SUBJECTS AND METHODS: Out of the AMI patients who enrolled in the Korea AMI Registry, 4444 female patients were included in this study. Patients were divided into two groups-non-smoker and smoker-according to their current smoking status. We compared in-hospital mortality and major adverse cardiac events (MACE), including cardiac death, myocardial infarction, repeated percutaneous coronary intervention (PCI), or coronary artery bypass grafting during the one-year clinical follow-up period between two groups. RESULTS: The non-smoker group had more hypertension (HTN) and diabetes mellitus. The levels of total cholesterol, triglyceride, and low-density lipoprotein cholesterol were higher in the non-smoker group. However, in-hospital mortality was significantly higher in the smoker group (1.0% vs. 2.4%, p=0.002), and cardiac death during the 12-month clinical follow-up was significantly more frequent in the smoker group (2.2% vs. 4.5%, p=0.003). Total MACEs during the 12 months were higher in the smoker group (4.9% vs. 6.8%, p=0.014). Smoking and HTN were independent predictors of MACE {odds ratio (OR): 1.742, 95% confidence interval (CI): 1.010-3.000, p=0.046; OR: 1.573, 95% CI: 1.003-2.466, p=0.049, respectively}. CONCLUSION: Female smokers with AMI showed significantly higher in-hospital mortality and MACE rates during the one-year clinical follow-up period.
