Background: The effect of psychological health on cardiovascular disease is an underappreciated yet important area of study. Method: A systematic search of electronic databases was conducted from inception through November 2021 for prospective studies evaluating optimism and adverse outcomes. Pooled hazard ratios were calculated in random-effects meta-analyses. Results: Pooled analysis of six studies (n = 181,709) showed a pooled hazard ratio of 0.87 (95% CI, 0.82-0.92) for all-cause mortality among those with more optimistic mindset. Analysis of seven studies (n = 201,210) showed a pooled hazard ratio of 0.59 (95% CI, 0.37-0.93) for cardiovascular disease. Conclusions: In this pooled meta-analysis, optimism was associated with a reduced risk of all-cause mortality and of cardiovascular disease.
