Reynolds LM, Zamora C, Lee UJ, et al. - The present study was conducted to explore tobacco use prevalence and longitudinal patterns of tobacco product transitions in adults (≥18 years) of the nationally representative PATH (Population Assessment of Tobacco and Health) study, from 2013 to 2014 (Wave 1) through 2016 to 2018 (Wave 4). Researchers categorized prevalent cardiovascular disease (CVD) through a self‐report of having had a heart attack, heart failure, stroke, or other heart condition. They analyzed 2,615 participants with self‐reported CVD at Wave 1. As per the findings, over one fourth of adults with prevalent CVD use tobacco products and few quit smoking over the 4 waves of the PATH data set, despite known harmful cardiovascular effects.
