ABSTRACT
OBJECTIVE:
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. MAINMEASURES:
Partial pressure of O(2) (P o (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 P o (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 P o (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.
