Abstract

Evaluating various parameters, including preoperative cardiorespiratory fitness markers, is critical for patients with morbid obesity. Also, clinicians should prescribe suitable exercise and lifestyle guideline based on the tested parameters. Therefore, we investigated cardiorespiratory fitness and its correlation with preoperative evaluation in patients with morbid obesity scheduled for laparoscopic sleeve gastrectomy. A retrospective cross-sectional study was conducted with 38 patients (13 men and 25 women; mean age, 34.910.9 years) scheduled for laparoscopic sleeve gastrectomy. Cardiopulmonary exercise stress tests were also performed. Measured cardiopulmonary responses included peak values of oxygen consumption (VO2), metabolic equivalents (METs), respiratory exchange ratio, heart rate (HR), and rate pressure product. Body composition variables were analyzed using bioimpedance analysis, laboratory parameters (hemoglobin A1c, lipid profile, inflammatory markers), and comorbidities. In addition, self-reported questionnaires were administered, including the Beck Depression Inventory (BDI), Hamilton Depression Rating Scale (HDRS), Short-Form Health Survey (SF-36), and Moorehead-Ardelt Quality of Life Questionnaire (MAQOL). The average body mass index (BMI) and percent body fat were 39.85.7 kg/m2 and 46.26.1%, respectively. The VO2peak/kg, METs, RERpeak, HRpeak, RPPpeak, age-predicted HR percentage, and VO2peak percentage were 18.63.8mL/min1/kg1, 5.3 1.1, 1.10.1, 158.519.8, 32,414.46,695.8mm Hg/min1, 85.28.8%, and 76.114.8%, respectively. BMI (P=.026), percent body fat (P=.001), HRpeak (P=.018), erythrocyte sedimentation rate (P=.007), total BDI (P=.043), HDRS (P=.025), SF-36 (P=.006), and MAQOL (P=.007) scores were significantly associated with VO2peak/kg. Body fat percentage (P.001) and total SF-36 score (P.001) remained significant in the multiple linear regression analysis. Various cardiorespiratory fitness markers were investigated in patients with morbid obesity who underwent the sleeve gastrectomy. Peak aerobic exercise capacity was significantly associated with preoperative parameters such as body fat composition and self-reported quality of life in these patients. These results could be utilized for preoperative and/or postoperative exercise strategies in patients with morbid obesity scheduled for laparoscopic sleeve gastrectomy.
