The present study examined resting levels of and stress‐related changes in blood pressure, peripheral vasomotor activity, heart rate, heart rate variability, electrodermal activity, and serum lipids in young men classified as Type A (coronary prone) or Type B (non‐prone) by a structured interview method. Stress was induced during two preliminary tasks by the occurrence of noise alone, failure alone, or noise plus failure. The results showed that during rest the groups differed only in vasomotor activity, the A's being more constricted than the B's. During work on the tasks, the groups were substantially the same in heart rate and blood pressure; however, the A's showed greater sympathetic arousal than B's in skin conductance level and spontaneous response rate. Extreme A's showed higher serum cholesterol than B's both before and after testing, and also showed a larger effect of noise on triglyceride levels than did B's.
