Implication

Does not support clinical screening for Type A behavior; leaves open its causal role in CHD via reactivity.

Key Points

To examine psychophysiologic cardiovascular responses to cognitive stress in Type A and Type B individuals with and without coronary heart disease.
Assessed 58 normotensive adult male volunteers, including 24 with documented coronary heart disease (CHD) not taking beta-blockers and 34 disease-free controls.
Classified behavior patterns using the Structured Interview (SI) and the Jenkins Activity Survey (JAS).
Measured heart rate (HR), systolic blood pressure (SBP), and diastolic blood pressure (DBP) during baseline and during frustrating cognitive tasks.
CHD patients exhibited significantly greater DBP elevations during experimental stress tasks than non-CHD controls, independent of Type A or B behavioral classification.
Type A men defined by the Structured Interview showed significantly larger stress-induced increases in SBP and DBP than Type B men, while changes in HR and task performance did not differ.
JAS-defined typology showed no significant relationship with SBP, DBP, or HR reactivity during tasks.

Structured PICO

Does Type A behavior pattern increase cardiovascular reactivity during cognitive stress in men with and without coronary heart disease?

Population

58 adult male volunteers with normotensive resting blood pressures, including 24 with a history of myocardial infarction or clinically diagnosed angina pectoris (not on beta-blockers) and 34 free of coronary disease.

Intervention

Type A behavior pattern (assessed by Structured Interview and Jenkins Activity Survey) subjected to difficult and frustrating cognitive tasks.

Comparator

Type B behavior pattern subjected to the same cognitive tasks.

Outcome

Changes in heart rate (HR), systolic blood pressure (SBP), and diastolic blood pressure (DBP) during cognitive tasks.surrogate

Type A behavior pattern and pre-existing coronary heart disease are independently associated with heightened blood pressure reactivity during cognitive stress.
