Zheng and colleagues at Sun Yat Sen University in China reported studies with a newly designed sequenced pulsation system using four sets of compression bladders on the patient’s legs, buttocks and arms. In these trials, effects of the sequenced system were studied in patients with angina pectoris and acute myocardial infarction. In more than 90 percent of the 200 patients with angina pectoris, this device provided long-term symptomatic relief with minimal relapse (excerpted from the University of San Francisco web site).

Favorable results reported by Chinese investigators, led scientists at the Health Sciences Center at the State University of New York at Stony Brook, to reassess the efficacy of external counterpulsation in treatment of patients with chronic angina pectoris. Their studies were performed using a newly developed and “enhanced” counterpulsation system.
