Research has consistently shown that hostility, which includes cynicism, anger, and aggression, is the most predictive Type A personality characteristic for heart disease. Hostile individuals tend to have higher levels of stress hormones and inflammation, which can damage the cardiovascular system over time. Compulsiveness, competitiveness, and chronic irritability are also characteristic of Type A personalities but have not been shown to be as strongly linked to heart disease as hostility.
