Introduction. Cardiopulmonary exercise testing (CPET) is a useful tool for assessment patients’ functional capacity after an acute coronary event. Aim: evaluation of functional capacity by CPET at 3 months after myocardial revascularization by coronary artery bypass grafting (CABG) or percutaneous coronary angioplasty (PCI). Methods. A prospective study that included 114 patients (mean age-61.0±8.2 years, 89.4% being men), who were divided into 2 groups according to the type of myocardial revascularization performed 3 months ago: CABG (40.3%) or PCI (59.7%). Echocardiography and CPET were performed in all subjects. Statistical parameters used: mean and standard deviation, percentages, t-Student test. Results. Initial heart rate (HR) was significantly higher in patients post-CABG (79.6 ± 9.5 vs 74.0 ± 11.8c/min, p < 0.05), but the maximum HR reached during exercise prevailed in the post-PCI group (114.8 ± 16.7 vs 106.7 ± 15.2c/min, p < 0.05). Thus, the HR reserve was lower in post-PCI patients (43.6 ± 17.2 vs 51.1 ± 15.0c/ min, p < 0.05). The work rate was similar in both groups (CABG-104.5 ± 35.5W, PCI-112.2 ± 34.6W, p = 0.3). However, peak oxygen consumption (VO2p) as well as VO2p related to body mass and work rate were significantly higher in post-PCI patients (VO2p: 1280.9 ± 351 vs 1108.4 ± 370ml/ min, p = 0.05; VO2/kg: 15.6±4.3 vs. 12.6 ± 3.7ml/min/kg, p < 0.01; VO2/WR: 8.0 ± 2.0 vs. 6.3 ± 2.2ml/min/W, p < 0.01). The oxygen uptake efficiency slope (OUES) also registered higher values in the PCI group (2011.7 ± 481 vs 1809.4 ± 479, p = 0.05). Conclusion. Although exercise capacity is similar at 3 months after myocardial revascularization by CAGB or PCI, VO2p, VO2/kg, VO2/WR and OUES are significantly higher in post-PCI patients |
