Abstract
Background. Reducing the duration of hospital stay of coronary surgery patients makes it necessary to develop reliable methods for the evaluation of their physical capacity. The aims of this study were as follows: 1. to assess the physical capacity of CABG patients. 2. to correlate the results of the treadmill test and the three-stage walking test. Material and methods. The study group consisted of 71 men aged 35-74 years qualified to undergo CABG with EF>40% and with no arrhythmias or cardias conduction defects. All patients received comprehensive rehabilitation care. The following tests were performed before (examination 1) and 3 months after CABG (examination 2): modified 3-stage walking test according to Bassey and treadmill exercise test to the Bruce protocol. Parameters evaluated comprised energy expenditure (E, kJ/ml), maximum workload (METs), oxygen consumption (VO2, ml/min/kg), and oxygen pulse (HRO2, ml/systole). Results. Significant improvements across all parameters examined were observed three months after CABG. Treadmill exercise test results were significantly better than the results of the walking test (p<0.001). There were correlations for oxygen pulse (r=0.63) and energy expenditure (r=0.51) between the treadmill test and self-paced walking test results at 3 months after CABG. Conclusions. The three-stage walking test may be useful in the evaluation of physical capacity. It may supplement clinical evaluation in post-CABG patients.

Abstract
Background. Contemporary cardiac surgery is increasingly relying on less invasive techniques to minimise hospital stay. We asses-sed the influence ofartificial ventilation time in CABG patients on ventilation parameters.Materiał and methods. The study enrolled 92 men aged 35-75 years following CABG undergoing rehabilitation. Patients were divi-ded into two groups based on duration of intubation: Group I included patients with artificial ventilation time (AVT) <17 hours and Group II those with AVT > 17h The correlation between AVT and respiratory capacity was assessed by spirometry before CABG, on fifth po-stoperative day, and at three months post-CABG.Results. The parameters decreased significantly in both groups on 5th post-operative day, except ERV (ns) in Group II. At 90 days post-surgery, all parameters had increased significantly compared to the 5th post-operative day readings in both groups, but FEV1 had not reached the preoperative level in either group. FVC EX was higher than pre-CABG value in Group I (ns) but not in Group II (p<0.05). VC failed to reach preoperative levels in both groups (Gr I ns, Gr II p<0.005).Conclusions. Most spirometric parameters tended to behave in the same manner irrespective of the duration ofAVT. Shorter AVThad a significant effect only on VC and FVC EX at 90 days after the surgery. The decrease in respiratory capacity was apparently related to the sternotomy associated with cardiac surgery.
