Which personality type is associated with higher risk of coronary heart disease due to aggression and hostility?

• A. Type D
• B. Type B
• C. Type C
• D. Type A

Answer: (D)

The main idea is how certain personality traits, especially hostility that comes with a Type A profile, influence heart disease risk. Type A people are known for competitiveness, urgency, and, importantly, hostility toward others. That hostility tends to produce stronger and more frequent physiological stress responses—higher blood pressure and heart rate, greater release of stress hormones, and inflammatory processes. Over time, these repeated arousal patterns can contribute to the development and progression of coronary artery disease.

The other types don’t center on aggression or hostile reactions to stress in the same way: Type B is more relaxed, Type C tends to be more reserved and agreeable, and Type D combines negative emotions with social inhibition but without the same hostility pattern linked to CHD risk. So, the personality type most associated with higher CHD risk due to aggression and hostility is the Type A profile.
