Abstract
Fortythree adult obese patients 31 women 721 and 12 men 279 were submitted to electrocardiogram ergometric test and echo Doppler cardiogram at presurgical stage and 1 year after RouxenY gastric bypass The statistical analysis utilized the Wilcoxon Student’s t and Shapiro–Wilk tests with 5 significance levelWeight was reduced from 1165 ± 215 to 80 ± 159 kg and body mass index from 418 ± 44 to 284 ± 38 kg/m2 Cardiac frequency was reduced from 779 ± 96 to 709 ± 78 bpm systolic pressure from 130 ± 20 to 120 ± 10 mmHg and diastolic pressure from 80 ± 10 to 80 ± 0 mmHg Ergometric tests showed distance covered from 3789 ± 1265 to 595 ± 1404 m metabolic coefficient from 67 ± 24 to 83 ± 26 ml O2/kg/min and oxygen consumption VO2 from 231 ± 84 to 30 ± 103 metabolic equivalents of task The echo Doppler cardiogram showed interventricular septum from 12 ± 2 to 10 ± 1 mm posterior wall from 11 ± 2 to 10 ± 1 mm and ventricular mass from 273 ± 85 to 216 ± 60 g There was improvement in the diastolic function with an increase in the E′/A′ and E/A relationship and the ejection fraction with an increase from 702 ± 72 to 729 ± 64
