Effect of worry, depression, and sensitivity to environmental stress owing to neurotic personality on risk of cardiovascular disease: A Mendelian randomization study.

Individuals with high neuroticism who are more susceptible to depressive symptoms are at higher risk for developing heart failure and myocardial infarction and should be more carefully evaluated for CVD risk in clinical settings. These individuals can potentially benefit from interventions aimed at reducing depressive symptoms to decrease CVD risk. There is no evidence to suggest that being sensitive to environmental stressors or being more worried can increase the risk for CVD.
