Objective: To evaluate the effectiveness of voluntary breathing exercise (VBE) on cardiac parameters and quality of life (QoL) of coronary heart disease (CHD) patients is 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 groupâ��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.
