Abstract
Objective: To evaluate the effectiveness of voluntary breathing exercise (VBE) on cardiac parameters and quality of life (QoL) of coronary heart disease (CHD) patients undergoing percutaneous coronary intervention (PCI). Method: From September 2015 to February 2016, CHD patients undergoing PCI from Cardiology Department of a hospital in Suzhou were randomly divided into non-VBE group (n=12) and VBE group (n=18). All patients received regular care. VBE group exercised using diaphragm breath, the ratio of expiration/inspiration >1, at least 6 breaths/min, 30 min/d and 5 days/w for 1 month. Cardiac parameters included heart rate (HR), Rate-pressure-Product (RPP), systolic blood pressure (SBP), diastolic blood pressure (DBP) and pulse pressure (PP). Cardiac parameters and QoL were compared at enrollment and one month. Results: There were no significant differences in cardiac parameters and QoL at baseline between two groups. Compared with the non-VBE group, VBE group had lower HR, RPP and SBP (72.83±7.11 vs. 81.50±8.03, P<0.01; 9182±1118.60 vs. 11178.92±1775.86, P<0.01; 126.28±11.97 vs. 136.67±12.68, P<0.05). Compared with baseline, the non-VBE group’s HR and RPP at one month increased significantly (5.17±5.62, P<0.01; 978.58±981.48,P<0.01), whereas HR and RPP in the VBE group reduced statistically (-4.56±56.24, P<0.01; -697.94±1325.16, P<0.05). QoL of the VBE group was significantly improved (87.61±12.75 vs 70.33±14.13, P<0.01) compared with that of the non-VBE group. QoL at one month was significantly improved compared with baseline in VBE group (13.89±11.05, P<0.01), whereas the same change was not seen in the non-VBE group. Conclusion: VBE can improve cardiac parameters and QoL in CHD patients undergoing PCI.
