N2 - Background: Depression and anxiety may be significant prognostic factors after myocardial infarction (MI). Thus, we investigated depression and anxiety prevalence among older MI survivors and their impact on mortality, stroke, and recurrent MI. Methods: This population-based cohort study used the Korean National Health Insurance Service database for data concerning individuals aged 66 years who participated in the National Screening Program from 2009 to 2016. Overall, 11,721 individuals with MI history and 58,605 age- and sex-matched controls were included and followed up until 2019. The presence of depression and anxiety was assessed 2 years before and after participation in the program. Mortality and major adverse outcomes, defined as a composite outcome comprising mortality, stroke, and recurrent MI, were analyzed. Results: Depression and anxiety prevalence among MI survivors was 20.4 % and 30.3 %, respectively. Crude odds ratios for depression and anxiety, compared with the control group, were 1.207 (1.148–1.269) and 1.078 (1.032–1.126), respectively. During the follow-up, individuals with depression, anxiety, or both showed increased hazard ratios (HRs) for mortality and major adverse outcomes; after adjustments, their HRs were 1.442 (1.182–1.759), 1.129 (0.960–1.328), and 1.498 (1.263–1.776), respectively, for mortality and 1.505 (1.289–1.758), 1.158 (1.021–1.314), and 1.530 (1.337–1.751), respectively, for major adverse outcomes. Limitations: Although this was a nationwide cohort study, the MI, depression, and anxiety diagnoses were based on diagnostic codes. Conclusions: Higher depression and anxiety prevalence was observed among older MI survivors. Depression and anxiety occurrence correlated with increased adverse clinical outcomes after adjustments.
