Purpose of review: Does optimism contribute to superior cardiovascular health? We examined prospective studies investigating the connections between optimism and cardiovascular health and examining the biological and behavioral mechanisms that may mediate such connections.
Recent findings: Optimism, independent of sociodemographic, medical, and negative psychological factors, has been prospectively associated with a lower risk of cardiovascular disease and lower rates of cardiac and all-cause mortality. The mechanisms by which optimism may prevent cardiovascular disease remain unclear, but one mechanism may be through health behaviors. Indeed, optimism has been linked with physical activity, healthy diet, and smoking cessation, all of which are associated with better cardiovascular health. Additional studies are needed to: (1) understand the relationships between more dynamic measures of optimism and health outcomes, (2) delineate the mechanisms underlying the relationships between optimism and cardiovascular health, and (3) assess the potential for interventions to modify optimism.
