Abstract：Objective To systematically review the influence of Tai Chi exercise on blood pressure in patients with coronary heart disease (CHD). Methods The databases of PubMed, EMbase, Cochrane, CNKI, WanFang Data, VIP and CBM were retrieved for choosing the clinical studies on Tai Chi exercise as a therapeutic measure in CHD patients with treatment course over 1 month. Meanwhile, the bibliographies related to retrieved and published systematic reviews about Tai Chi exercise intervening CHD were retrieved manually. The screen, review and data extract of all literature were carried out independently by 2 researches. The data of complete case information was analyzed by using RevMan5.3 software, and included studies were given evidence review by using online GRADEpro software. Results There were totally 6 studies collected including 4 randomized controlled trials (RCT) and 2 nonrandomized controlled trials (N-RCT) involved 280 patients. There were no reports on severe cardiovascular events and complications. Tai Chi exercise decreased instant blood pressure (BP) after exercise in CHD patients, but had no statistical significance compared with aerobic exercise (SBP: MD=-1, 95%CI:-3.89~1.89, P=0.50;DBP: MD=1, 95%CI:-0.62~2.62, P=0.23). Compared with control group, resting SBP seemed to have descending trend in Tai Chi group after Tai Chi exercise, but difference had no statistical significance (SBP: MD=-3.59, 95%CI:-8.70~1.52, P=0.17). Tai Chi exercise decreased significantly resting DBP in Tai Chi group compared with control group (MD=-5.50, 95%CI:-10.57~-0.43, P=0.03). The peak BP was slightly higher in Tai Chi group than that in control group but the difference had no statistical significance (SBP: MD=0.68, 95%CI:-11.10-12.45, P=0.91;DBP: MD=3, 95%CI:-3.28~9.28, P=0.35). GRADEprp evidence grading showed that evidence grade was low or very low. Conclusion Tai Chi exercise is safe and can reduce BP in CHD patients. Because of limitation of quantity and quality, more studies with higher quality are needed to verify the above conclusion needs.
