Prevalence and Prognostic Implications of Atherosclerotic Coronary Artery Disease in Type 2 Myocardial Infarction
Main finding · Major adverse cardiovascular outcomesResult — go to the resultAdjusted hazard ratio 1.95 95% CI 1.2–3.6Authors' conclusion
CAD is common among patients with T2MI and myocardial injury and is associated with poor long-term outcomes. Its presence may facilitate risk-stratification and represent a potential therapeutic target.
