To show possible relationships of exercise tolerance with pulmonary circulation in rehabilitated (R) patients with chronic obstructive pulmonary disease (COPD) we assessed results of symptom -limited treadmill exercise test (ET) and echocardiographic study: right ventricular diastolic dimension (RV), RV free wall dimension (RVW), left ventricular end-diastolic dimension (LVED), LV ejection fraction (LVEF). pulmonary artery acceleration time (AT) and maximal systolic tricuspid gradient (GT) in 27 R COPD patients, mean age 61.8 +or- 11 years and in 19 control (C) COPD patients, mean age 66.6 +or- 8 years before and after 24 months of comprehensive rehabilitation. After study R patients increased number of METs achieved during ET from 3.94 +or- 1.8 to 4.77 +or-2.0, p=0.003 as opposite to C group (from 2.7 +or- 0.2 to 2.5 +or- 0.1 METs, NS). Echocardiography showed that after study R patients had decreased RV p= 0.001 and RVW p= 0.001. These morphologic changes were accompanied in R COPD patients by tendency to increase AT, and to decrease GT (available in 21 patients). In C COPD patients we found after observation worsening of AT p=0.05 and GT p=0.005, accompanied by enlargement of RVW (p= 0.008). No change in LVED and LVEF were found in both groups after study.
Summarizing, results of this study suggest possible relationships of increased exercise tolerance in rehabilitated COPD patients with beneficial effect of long term rehabilitation on pulmonary circulation.
