Beyond Type A: hostility and coronary heart disease--implications for research and practice.

Research into the psychological and behavioral correlates of coronary heart disease (CHD) has gone beyond the traditional description of the Type A behavior pattern and is focusing instead on components that may be more sensitive predictors of CHD endpoints. One component being investigated frequently is hostility. Many questions related to hostility and CHD remain unanswered and warrant further research. Implications for practice include a need for reexamination of standard risk reduction programs in light of current knowledge.
