Aim Anger expression is associated with an increased risk of cardiovascular disease. This positive association was confined to individuals with lower perceived social support and outdoor recreational activity. However, the effects of retirement status remain unclear. This study aimed to investigate whether retirement status after the age of 60 years modifies the association between anger expression and the risk of cardiovascular disease in the Japanese population. Methods This longitudinal study included 499 community‐dwelling retired and employed workers aged 60–79 years, who completed a cardiovascular risk survey in 1997. A Cox proportional hazards model was used to estimate the hazard ratios and 95% confidence intervals of incident cardiovascular disease (ischemic heart disease and stroke) according to anger expression in retired and employed workers after adjusting for potential cardiovascular risk factors. Results A total of 37 participants experienced incident cardiovascular disease during the mean follow‐up period of 14.8 years (standard deviation 5.5 years). In retired workers, anger expression was associated with an increased cardiovascular disease risk, whereas no such association was observed in employed workers. The respective hazard ratio per one‐standard deviation increment of total anger expression was 1.77 (95% confidence interval 1.29–2.43) and 1.03 (95% confidence interval 0.64–1.66; P for interaction = 0.036) among retired and employed workers, respectively. Conclusions A positive association between anger expression and the risk of cardiovascular disease was confined to retired workers, suggesting that continuing work after retirement age could reduce anger expression‐related cardiovascular disease risk.
