A comparison of hypertensive and nonhypertensive coronary care patients' cardiovascular responses to visitors.
Patients with and without hypertension in a coronary care unit (n = 24) were compared with respect to cardiovascular responses to both a family visit and an interview by an investigator. Variables for each of the four cardiovascular indicators (systolic blood pressure, diastolic blood pressure, heart rate, and premature ventricular contractions) included the value before, the highest value during, the lowest value during, and the value after each social interaction condition. The highest group means for systolic blood pressure and heart rate were significantly higher for patients with hypertension than for patients without hypertension under both the interview and visit conditions. Differences in cardiovascular responses were not significantly greater for family visits than for interviews for patients with hypertension compared with those without hypertension. Thus, although hypertensive patients had greater cardiovascular reactivity to both social interaction conditions than nonhypertensive patients in the coronary care unit, family visits were no more physiologically stressful than a comparative interaction condition.
