At baseline testing, CPET parameters in both the
intervention and control group patients (Table 4) did
not show any statistically significant difference. Repeat
CPET at three weeks (Table 4) showed statistically
significant improvement in all CPET parameters except
anaerobic threshold (AT), heart rate and ventilatory
equivalents for oxygen and carbon dioxide in
intervention group. The findings indicate improved
cardiovascular function as well as exercise capacity
which can be attributed to PR programme. In the
control group patients who received only the usual care
for three weeks, on the other hand, none of the CPET
parameters, except breathing reserve showed any
