ABSTRACT

Objective: To determine the frequency of smokers and to compare the frequency of smokers among patients with inferior and anterior acute myocardial infarction amongst patients presenting with acute myocardial infarction at a Tertiary Care Hospital.

Subjects And Methods: This cross-sectional study was conducted on 226 at the Adult Cardiology Department of the National Institute of Cardiovascular Disease (NICVD), Karachi for six months from 20-07-2019 till 20-01-2020. After obtaining verbal consent, researchers prospectively collected data from the participants. The study included 226 patients who were diagnosed with the appropriate conditions. Frequency and percentages were used to present qualitative data, while mean and standard deviation were used to present quantitative data.  To see how to effect modifiers affected the outcome, researchers used stratification to keep track of them. For statistical significance, the post-stratification chi-square test was used.

Results: A total of 226 presenting with acute myocardial infarction were included in this study. The mean age in our study was 55.92±10.49 years. Out of 226 patients with acute myocardial infarction, 130 (57.5%) and 96 (42.5) smoked and did not smoke respectively. Comparison of smoking status in patients who had anterior and inferior myocardial infarction showed that 39 (53.4%) and 51 (51%) smoked respectively.

Conclusion: Smoking is a well-recognized strong modifiable risk factor and predictor of multivessel disease.  Smoking cessation has been consistently associated with a mortality benefit in both stable coronary artery disease and post-acute coronary syndromes. Consequently, smoking cessation is one of the cornerstones of secondary prevention despite the improvement in the management of ACS with PCI and pharmacotherapy
