Abstract

BACKGROUND: The literature on suicide mortality rates in patients with cardiovascular diseases (CVDs) is limited.

METHODS: Taiwan National Health Insurance Research Database and Taiwan Death Registry were retrieved for patients with the 5 CVDs: congestive heart failure (CHF), acute myocardial infarction (AMI), ischemic stroke (IS), hemorrhagic stroke (HS), and pacemaker implantation (PMI) between January 1, 2001, and December 31, 2015. We excluded patients younger than 15 years old. The primary outcome was suicidal death. The standardized mortality ratio (SMR) was used to compare the risk of suicidal death in the 5 CVDs to the general population.

RESULTS: From 2001 to 2015, there were 212,206 patients with CHF, 178,894 patients with AMI, 475,359 patients with IS, 189,555 patients with HS, and 64,173 patients with PMI. The SMR per 100,000 person-year, 95% CI was 59.6 (54.5-64.8) for those with CHF, 44.6 (40.1-49.1) for AMI, 57.6 (54.7-60.5) for IS, 44.6 (40.2-49.0) for HS, 54.0 (45.9-62.0) for PMI, and 20.3 (20.1-20.4) for the general population. Patients with CHF patients had the highest SMR (2.10), followed by IS (1.96), PMI (1.86), HS (1.65), and AMI (1.46). The SMRs for patients with CVDs peaked at year 2 after the diagnosis, declined for patients with AMI, IS, and HS, increased and decreased for PMI alternately, and reached very similar values all five CVDs after 10th year after the diagnosis.

CONCLUSIONS: Patients with acute CVD with AMI, IS, and HS had suicide death rates peaked early after diagnosis, but patients with chronic CVD with CHF and PMI had suicide death rates that increased progressively. In addition, patients with PMI, CHF, IS had highest association with psychiatric illness and patients with PMI who were of young to middle age had highest suicide death rate.
