EFFECT OF AEROBIC PHYSICAL TRAINING IN PACIENTS WITH CORONARY ARTERY DISEASE PARTICIPANTS OF A CARDIAC REHABILITATION PROGRAM

Abstract

Study Model: Retrospective. Study objectives: Evaluate the effect of aerobic physical training in cardiovascular variables in patients with coronary artery disease participants of a Cardiovascular Rehabilitation Program. Methods: Patients with stable coronary artery disease were included and were analyzed the cardiovascular variables of exercise testing, carried out before and after a minimum period of 12 weeks of aerobic physical training in a Cardiovascular Rehabilitation Program, from February 2002 to July 2005. Results: A significant increment (p <0.0001) of maximal oxygen consumption (VO2 max) was observed after the cardiovascular rehabilitation (30.1 ± 9.5 versus 35.5 ± 8.8 ml/kg/min). The difference of the VO2 max had negative correlation with the initial physical capacity, with greater benefits in patients with smaller initial values of VO2  max. Significant differences were not observed in maximal systolic blood pressure and double product, and a small difference was observed in maximal heart rate. The improvement in ischemic threshold was more pronounced, with an increment of 7.4 ml/kg/min in oxygen consumption, with statistical significance (p < 0.0001) (21.0 ± 6.9 versus 28.4 ± 8.2 ml/kg/min). Conclusions: The cardiovascular rehabilitation improved physical capacity and ischemic threshold in patients participants of a Cardiovascular Rehabilitation Program. The benefit in physical capacity was greater in patients with smaller initial values of maximal oxygen consumption.
