  • Title: Effects of stress management on blood pressure and other cardiovascular variables.
    Author: Albright GL, Andreassi JL, Brockwell AL.
    Journal: Int J Psychophysiol; 1991 Aug; 11(2):213-7. PubMed ID: 1748597.
    Abstract:
    Blood pressure and impedance cardiography derived measures of heart rate, stroke volume, cardiac output and total peripheral resistance were measured in 16 persons before and after participation in a comprehensive program of stress management that included home monitoring of blood pressure and feedback of finger skin temperature during relaxation. Ten of the subjects were hypertensive and six were normotensive. Baseline measures of systolic and diastolic blood pressure and heart rate decreased significantly after participation in the program. In addition, reactivity to a psychological stressor (oral quiz) was significantly lower as revealed in reduced systolic and diastolic pressure, heart rate and cardiac output at the second assessment. A reduction in sympathetic nervous system activity is postulated as a possible mechanism for the changes observed.
