SMOKING AND ITS ROLE IN MYOCARDIAL INFARCTION RECURRENCE AMONG INDIVIDUALS UNDER 45

Objective: The rising prevalence of cardiovascular diseases in younger populations, driven by changes in lifestyle and an increase in risk factors, is becoming a significant concern. Among these, smoking stands out as a formidable risk factor for the premature onset of cardiovascular pathologies, notably myocardial infarctions (MI). This study delves into the prevalence of cardiovascular risk factors, with an emphasis on smoking and its correlation with MI recurrence, in individuals under 45 years of age. This investigation seeks to elucidate the frequency and impact of diverse cardiovascular disease risk factors, focusing on smoking status among patients under 45 years who have experienced an MI. It aims to discern the relationship between smoking habits and the recurrence of MI within this demographic.Design and method: Engaging a cohort of 163 individuals under the age of 45 who have suffered an MI, this study meticulously analyses the prevalence of smoking and its variants within this group. It further explores the association between smoking status and the incidence of prior MI events, employing a comprehensive evaluative framework. Results: Analysis revealed a gender distribution across smoking statuses, with 21.7% of non-smokers, 69.2% of smokers, and 9.2% of former smokers being male, the remainder being female. Notably, prior MI occurrences were reported in 7.1% of non-smokers, 50% of smokers, and 42.9% of former smokers, revealing a statistically significant difference among the groups (p < 0.001), highlighting the strong association between smoking history and MI recurrence rates. Conclusions: The study underscores a significant association between smoking and increased MI recurrence among younger patients, advocating for robust smoking cessation initiatives tailored to this demographic. It accentuates the pivotal role of lifestyle modifications in mitigating cardiovascular risk, reinforcing the imperative for preventive strategies aimed at curtailing the recurrence of MI in younger populations.
