Cardiopulmonary evaluation before and after gastroplasty for morbid obesity

This work was conducted to evaluate cardiopulmonary performance before and after gastroplasty in morbid obesity. Fifteen male patients with morbid obesity were included in this study. The results showed a significant reduction in body weight of about 38% and there was about 31% reduction in BMI after surgery. The improvement in VC [L] and MVV was statistically significant. The parameters of exercise tolerance were improved after surgery. The power attained at maximal exercise was significantly increased after surgery. It was concluded that vertical band gastroplasty was followed by a marked reduction in body weight with a subsequent improvement in pulmonary function, exercise tolerance, ventilatory reserve as well as cardiac reserve
