Key result
Dual cigarette and e-cigarette use is linked to premature coronary atherosclerosis and STEMI in young adults.
Why the study?
STEMI in very young adults is rare and typically non-atherosclerotic, but rising electronic cigarette use raises concern for premature coronary atherosclerosis.
Case Report (n=1)
No
This case highlights that premature atherosclerotic STEMI can occur in very young adults with combined tobacco and electronic cigarette use alongside early metabolic abnormalities.
Should not change practice; hypothesis-generating for dual nicotine exposure in very young STEMI.
Background ST-elevation myocardial infarction (STEMI) in very young adults is rare and is commonly attributed to non-atherosclerotic mechanisms. Atherosclerotic coronary artery disease in this age group is exceptional and warrants thorough evaluation of contributing risk factors. The increasing prevalence of electronic cigarette use among young individuals raises concern regarding its potential role in premature coronary atherosclerosis. Case Summary A 21-year-old man presented with a 3-hour history of typical anginal chest pain. He had a significant history of combined tobacco cigarette and electronic cigarette use for more than five years. Electrocardiography demonstrated ST-segment elevation in the inferior leads, consistent with inferior STEMI. Laboratory testing revealed elevated troponin I, leukocytosis, and prediabetes (HbA1c 6.2%). Coronary angiography identified an atherosclerotic culprit lesion with approximately 80% stenosis and thrombus formation in the mid right coronary artery. The patient underwent successful primary percutaneous coronary intervention with TIMI grade III flow. Transthoracic echocardiography showed preserved left ventricular systolic function. Further evaluation excluded autoimmune and secondary thrombotic etiologies. The patient recovered well, was discharged on guideline-directed medical therapy, and remained asymptomatic at 3-month follow-up without recurrent ischemic events. Discussion This case highlights premature atherosclerotic STEMI in a very young adult without established cardiovascular disease or autoimmune etiology. Chronic exposure to combustible and electronic cigarettes has been associated with endothelial dysfunction and vascular inflammation, which may contribute to accelerated atherosclerosis.. Clinicians should maintain a high index of suspicion for atherosclerotic myocardial infarction in young patients with significant nicotine exposure and emphasize early prevention and cessation strategies in accordance with current European Society of Cardiology guidelines.

Baskoro et al. (2026) conducted a case report in ST-Elevation Myocardial Infarction (n=1). Tobacco and electronic cigarette use was evaluated. Prolonged exposure to both combustible tobacco and electronic cigarettes may contribute to premature coronary atherosclerosis and acute STEMI in very young adults.
