In Hospital Outcome Among Smoker and Nonsmoker Patients Presented with ST-Elevation Myocardial Infarction Undergoing Primary Percutaneous Coronary Intervention

Objective: To determine the association between smoking and in-hospital outcomes in patients presented with ST-Elevation Myocardial Infarction undergoing primary percutaneous coronary intervention (PCI). Methodology: This prospective cohort study was conducted at Department of Cardiology, National Institute Cardiovascular Disease (NICVD), Karachi, from November 9, 2020 to May 8, 2021. All (current smoker, ex-smoker non-smoker) age 18 years 85 years, both gender, diagnosed STEMI accordance operational definition underwent PCI were included. Patients divided into two groups, expose (smoker) unexposed (nonsmoker). Before PPCI demographic detail noted body mass index calculated after management then performed. In hospital outcome i.e. heart failure, mortality transient ischemic attack assessed within 30 days stay PCI. collected data entered proforma. Results: Mean ±SD exposed group 56.5±11.8 non-exposed 57.7±12.1 years. wise distribution 82 (70.7%) males 34 (29.3%) females enrolled 80 (68.9%) 36 (31.1%) included group. Risk failure 1.4 5.0 times more likely as compared [Relative 1.444 respectively. While risk 0.2 less 0.222] P value found be significant (P=0.030). Conclusion: It is concluded that vice versa case mortality, but we cannot rule out residual confounders.
