Diabetes and hypertension were more prevalent in women, and patients equally received interventional procedures post‐infarction. Diabetes significantly reduced post‐infarction survival in men and women [HR = 2.02 (95% CI 1.21–3.36) and HR = 2.25 (95% CI 1.06–4.80), respectively]. However, young women had greater post‐infarction mortality in‐hospital and up to 1 year after discharge (4.23% <italic>vs</italic>. 2.21%, respectively; <italic>P</italic> = 0.005). Medical chart review: diabetes and hypertension were more prevalent in women, while men were more obese. There were no significant sex differences in typical presenting symptoms, or in interventional procedures post‐infarction.</p> </sec> <sec id="dme12084-sec-0004" sec-type="section"> <title>Conclusions</title> <p>Young men and women with acute myocardial infarctions equally presented with retrosternal chest pain, although fewer women sought medical attention for retrosternal chest pain before admission. Diabetes and hypertension were more prevalent in young women, and mortality was higher in young female patients. Our results highlight the continued need for diabetes prevention and control in young patients, especially women.</p> </sec> </abstract>
