Most studies about the trends of acute myocardial infarction (AMI) were based on the data from Western countries. In recent years, little information is available from Asia since 2010. This study assessed the nationwide trends of AMI in Taiwan from 2009 to 2015. Using data from the Taiwan National Health Insurance Research Database, we identified 100,570 adult patients hospitalized for AMI from 2009 to 2015 and examined the temporal trends in the incidence of AMI. Overall, the age- and gender-adjusted incidence of AMI (per 100,000 persons) remained constant from 49.8 in 2009 to 50.7 in 2015. The incidence of AMI increased 30.3% and 29.4% in the young male and female populations (<55 years), whereas in other age groups, the incidence decreased or remained unchanged. The ratio of non-ST-segment elevation MI (NSTEMI) to STEMI incidence increased from 1.93 in 2009 to 2.47 in 2015. In young men (<55 years), a 49.8% increase in NSTEMI was observed. The prevalence of dyslipidemia increased significantly and it was the most common risk factor of AMI in young patients. Despite being increasingly used, percutaneous coronary intervention and secondary preventive medications, including dual antiplatelet therapy, angiotensin converting enzyme inhibitor/angiotensin receptor blocker, β blocker and statin, were less prescribed for NSTEMI compared with STEMI. The in-hospital mortality of STEMI continued to decrease from 2013 to 2015 (8.8% to 7.6%), but not in NSTEMI (13.3% to 13.5%). In conclusion, our study revealed a marked increase of NSTEMI in young Taiwanese male population in recent years. Despite the increased utilization of percutaneous coronary intervention and guideline-recommended medications, the overall in-hospital mortality of NSTEMI remained stagnating in Taiwan.
