The effects of thermal biofeedback and autogenic training of cardiovascular reactivity: The joint USSR-USA behavioral hypertension treatment project

Cardiovascular reactivity (heart rate, systolic, and diastolic BP) to mental arithmetic and cold pressor were measured before and after treatment as part of the cross-cultural (USSR and USA) evaluation of thermal biofeedback and autogenic training (in comparison with self-relaxation) as treatments for mild hypertension in unmedicated males. There were no statistically reliable decreases in cardiovascular reactivity from before to after treatment. However, downward shifts in basal levels of systolic and diastolic BP at post-treatment led treated patients to have lower stress-induced levels of BP.The American portion of this research was supported by a grant from the NHLBI, HL-31189. We express appreciation to officials at the USSR Cardiology Research Center, Academician Igor Shkhvatsabaya, and Professor Vadim Zaitsev for their support, as well as to Dr. Steve Weiss, of NHLBI, for his instigation of this research.
