Alzahrani T, et al. - Researchers assessed the cross-sectional link between electronic cigarette (e-cigarette) use (never, former, some days, daily) and cigarette smoking (same categories) and myocardial infarction, using the National Health Interview Surveys of 2014 (n=36,697) and 2016 (n=33,028). They used a single logistic regression model including demographics (age, gender, BMI) and health characteristics (hypertension, diabetes, and hypercholesterolemia). An increased risk of myocardial infarction was observed in relation to daily e-cigarette use, adjusted for smoking conventional cigarettes as well as other risk factors. Lower odds of myocardial infarction were reported in women. History of hypertension, high cholesterol, and diabetes, as well as age, increased odds of a myocardial infarction. Myocardial infarction was significantly associated with former and some day cigarette smoking, while no significant link was seen with former and some day e-cigarette use.
