BackgroundStudies on the relationship between acute pancreatitis (AP) and acute coronary syndrome (ACS) are scant. We conducted a nationwide cohort study to investigate the incidence and risk of ACS in patients with AP.MethodsWe enrolled patients newly diagnosed with AP between 2000 and 2010 from the Taiwan National Health Insurance Research Database and randomly selected a control cohort without a history of AP after frequency-matching for age, sex, and index year at a ratio of 4:1 for each patient with AP. The follow-up period was from the index date of new AP diagnosis to the diagnosis of ACS, censoring, or the end of 2011.ResultsWe assessed 87â068 patients in the AP cohort and 348â272 participants in the control cohort for 508â991 and 2â301â317 person-years, respectively. The AP cohort exhibited a higher overall incidence of ACS than the control cohort (5.44 vs 3.03 per 1000 person-y). After adjustment for sex, age, and comorbidities, the AP cohort exhibited a 1.24-fold higher adjusted hazard ratio (aHR) of ACS (95% confidence interval = 1.19-1.30) than did the control cohort. When stratified by age, the patients with AP aged â¤39 years presented a 2.37-fold higher aHR of ACS than did their corresponding controls (95% CI = 1.88-2.99). Approximate one third of ACS developed within 1 month of AP occurrence.ConclusionsThis nationwide cohort study indicated that patients with AP are at an increased risk of ACS compared with those without AP.
