Abstract: Background: Cigarette smoking is a well-established risk factor for myocardial infarction (MI), yet the relationship between the age at which individuals last smoked and MI has been less extensively studied. This study examined the association between smoking history, measured by age last smoked, and self-reported heart attack among U.S. adults.  Methods: A cross-sectional analysis was conducted using the 2024 Behavioral Risk Factor Surveillance System (BRFSS) dataset. Adults with complete data on smoking history and myocardial infarction were included in our study. Poisson regression with robust standard errors was used to estimate adjusted prevalence ratios (PRs), while controlling for demographic, socioeconomic, and clinical covariates. Interaction and stratified analyses were performed to evaluate effect modification by age and sex.
