Clinical study on the method of reinforcing qi nourishing yin and promoting blood circulation to remove blood stasis in the treatment of restenosis after percutaneous coronary intervention / 国际中医中药杂志

ABSTRACT

Objective To observe the clinical effects of the method of reinforcing qi,nourish ing yin and promoting blood circulation to remove blood stasis in the treatment of restenosis after percutaneous coronary intervention.Methods 60 coronary heart disease patients who had accepted PCI treatment and occurred restenosis were randomly recruited into a control group and a treatment group,30 eases in each group.The control group received conventional therapy.The treatment group was treated with conventional therapy combined with TCM of reinforcing qi,nourishing yin and promoting blood circulation to remove blood stasis.Both groups were treated for 6 months.The clinical symptoms,coronary angiography or coronary artery CTA,blood lipids were observed.Results The total effective rate was 93.33％ and 66.67％ in the treatment group and the control group respectively,showing statistical difference (x2=8.787,P＜0.05).The patients' clinical symptoms in the treatment group were improved,such as chest pain,chest tightness,shortness of breath,fatigue,dry mouth [The scores were respectively(1.07± 1.01)、(1.33±1.21)、(1.47±1.17)、(1.53±1.14)、(1.53± 1.01),(P＜0.05) ].The treatment group demonstrated a significantly better therapeutic results than the control group [Thescoreswererespectively(2.07±1.53)、(2.27±1.46)、(3.73±1.46)、(3.73±1.87)、(3.13±1.63),(P＜0.05) ].The results of coronary angiography or coronary artery CTA showed that the narrow degree in the treatment group was no more aggravating and it had no new restenosis.After the treatment,the level of CHOL、TG、HDL-C、LDL-C in the treatment group was improved [They were respectively (4.55±0.44)mmol/L、(1.81±0.56)mmol/L、(1.26±0.38)mmol/L、(2.25±0.49)mmol/L,(P＜0.05) ].The improvement in CHOL、TG、LDL-C of the treatment group was better than that of the control group [They were respectively (4.86±0.63)mmol/L、(2.29±1.06)mmol/L,(2.60±0.73)mmol/L,(P＜0.05)].Conclusion The method of reinforcing qi,nourishing yin and promoting blood circulation to remove blood stasis could improve the patients clinical symptoms and blood lipids,and therefore spreventing restenosis.
