Key result
In Type A individuals, a competitive task elicited significantly greater changes in systolic blood pressure, heart rate, and pulse wave transit time compared to a non-competitive task, whereas no such differences were observed in Type B individuals.

Does a competitive task elicit greater cardiovascular reactivity and state-anxiety in Type A individuals compared to Type B individuals?
p-value: p=<0.01
Type A individuals exhibit exaggerated cardiovascular reactivity specifically during competitive interactions, providing a potential physiological link between Type A behavior and coronary heart disease.
Ishihara et al. (1997) conducted an RCT in Type A and Type B behavior pattern (n=72). Competitive Reaction Time task vs. Non-competitive Reaction Time task was evaluated on Changes in systolic blood pressure, heart rate, and pulse wave transit time (p=<0.01). In Type A individuals, a competitive task elicited significantly greater changes in systolic blood pressure, heart rate, and pulse wave transit time compared to a non-competitive task, whereas no such differences were observed in Type B individuals.
