| Part One: The impact of voluntary breathing exercise on heart rate and systolic blood pressure in theadults:ameta-analysisObjective: Tocollect randomized controlled trials of voluntary breathing exercise(VBE), and perform ameta-analysis to evaluate the effectsof VBE on heart rate(HR) and systolic blood pressure(SBP) in adults.Method:Cochrane Central Register of Controlled Trials(CENTRAL),MEDLINE, EMbase,OVIDdatabase,PEDro(www.pedro.org.au), CNKI,VIP, Wanfang Databaseand CBM were searched for randomized controlled trials(RCTs)on VBE in adults up to November 2014. The referencesof the included studies were searched as well. The languages of the articles are limited in Chinese and English. The qualities of the articles wereevaluated with PEDroscale.Twoinvestigatorsindependentlyevaluated the included studies and collected data. In case of any dispute, the third researcher was invited to judge to arrive at an agreement.The extracted data were analyzed using Rev Man 5.0 software, which was provided by the Cochrane website.Results:Atotal of 5RCTs were included, consisting offour English articles andone Chinese article. These studies includea total number of 269 people, with 133 in experimental groupsand 136 in control groups. Our results demonstrated that VBE showedsignificant benefitsin HR(WMD:-5.47, 95%CI:-8.83to-2.12)and SBP(WMD:-6.02,95%CI:-7.23 to-5.17)in adults.Conclusion: Our research indicatesthat VBE could remarkably improve HR and SBP inadults.Compared with other measurements, it is more practical, less cost and complications.Thus,VBE may serve as a promising self-care approach in cardiac rehabilitation.Part Two: Effectiveness of Voluntary Breathing Exercise on Cardiac Parameters and Quality of Life of Coronary Heart Disease Patients Undergoing Percutaneous Coronary InterventionObjective: To evaluate the effectiveness of voluntary breathing exercise(VBE) on cardiac parameters and quality of life(Qo L) 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 Qo L were compared at enrollment and one month. Statistical analysis was conducted using SPSS for windows 18.0. Inferential statistics include Paired-Sample T Test, Independent-samples T Testand Chi-square Test. P< 0.05 was accepted asbeing statistically significant.Results: There were no significant differences in cardiac parameters and Qo L at baseline between two groups. Compared with the non-VBE group, VBE group had lower HR, SBPand RPP(72.83±7.12 vs. 81.50±8.03, P<0.01; 126.28±11.97 vs. 136.67±12.68, P<0.05; 9182±1118.60 vs. 11178.92±1775.86, P<0.01). Compared with baseline, the non-VBE group’s HR at one month increased significantly(5.17±5.62, P<0.01), whereas HR in the VBE group reduced statistically(-4.56±56.24, P<0.01). Qo L 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. Qo L at one month was significantly improved compared with baseline in the 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 Qo L in CHD patients undergoing PCI. |
