Abstract:
To compare models of the postoperative hospital treatment phase after myocardial revascularization. Design: A pilot randomized controlled trial. Setting: Hospital patients in a hospital setting. Subjects: Thirty-two patients with indications for myocardial revascularization were included between January 2008 and December 2009, with a left ventricular ejection fraction (LVEF) ≥50%, 1-second forced expiratory volume (FEV 1 ) ≥60 and forced vital capacity (FVC) ≥60% of predicted value. Interventions: Patients were randomly placed into two groups: one performed prescribed exercises according to the model proposed by the American College of Sports Medicine (ACSM) and the other according to a periodized model. Main measures: Partial pressure of O 2 ( Po 2 ) and arterial O 2 saturation ( Sao 2 ), percentage of predicted FVC and total distance on the six-minute walking test (6MWT). Results: Twenty-seven patients were re-evaluated upon release from the hospital (ACSM = 14 and PP = 13). Five patients extubated for more than 6 hours in the postoperative period were excluded from the sample. In the preoperative period the variables Po 2 , Sao 2 , % FVC and 6MWT were similar. In the postoperative period, a reduction was observed for all parameters in both groups. Upon comparison of the groups, a difference was observed in Po 2 (ACSM = 68.0 ± 4.3 vs. PP = 75.9 ± 4.8 mmHg; P 〈 0.001), Sao 2 (ACSM = 93.5 ± 1.4 vs. PP = 94.8 ± 1.2%; P = 0.018) and 6MWT (ACSM = 339.3 ± 41.7 vs. PP = 393.8 ± 25.7 m; P 〈 0.001). There was no difference in % FVC. Conclusion: Patients after myocardial revascularization following a periodized model of exercise presented a better intra-hospital evolution when compared to those using the ACSM model.
