Why the study?
Does propranolol medication reduce the intensity of Type A behavior and cardiovascular responses in coronary patients?
Does propranolol medication reduce the intensity of Type A behavior and cardiovascular responses in coronary patients?
Propranolol use in coronary patients is associated with lower intensity of Type A behavior and blunted cardiovascular responses to stress, suggesting a physiological substrate for Type A behavior.
No takes yet. Share an insight, caveat, or question.
Propranolol use was associated with lower Type A intensity and blunted reactivity in coronary patients; leaves open causal effects on behavior, needing prospective trials.
Krantz et al. (1982) studied this question.
