While individual negative emotions like depression are known risk factors for heart disease, the cumulative effect of chronically experiencing several negative emotional states is a more powerful predictor. Research indicates that a composite variable combining attributes such as depression, anxiety, hostility, and anger predicts the onset of heart disease more effectively than any of these factors considered in isolation.

Combined Negative Emotional States as a Strong Predictor of Heart Disease

A longitudinal study of Vietnam War veterans by Boyle, Michalek, & Suarez (2006) examined the impact of various psychological states on cardiovascular health.
