ObjectiveTo explore the effect of Yiqi Huoxue decoction on the cardiac rehabilitation in coronary heart disease patients after percutaneous coronary intervention. MethodsA total of 150 patients with coronary heart disease underwent percutaneous coronary intervention (PCI) were selected and divided into control group or study group according to random number table method, with 75 cases in each group. Both groups were administered conventional western medicine, whereas the study group was treated with Yiqi Huoxue decoction additionally, with three-month treatment and six-month follow-up. The Short Form 36-item Health Survey (SF-36) score and traditional Chinese medical syndrome score were recorded at the time of hospital admission, 2 months and 6 months after discharge, respectively.The result of cardiac function evaluation indexes were recorded at the time of hospital admission and 6 months after discharge. The incidence of major adverse cardiac events was compared between the two groups. ResultsCompared to the time of hospital admission, the score of SF-36 were decreased 2 and 6 months after discharge in both groups (all P＜0.05), and 6 months after discharge, the score of SF-36 was significantly lower in the study group than in the control group (P＜0.05). Six months after discharge, left ventricular end diastolic diameter（LVEDD）, left ventricular end systolic diameter（LVESD）, stroke volume（SV）, left ventricular ejection fraction（LVEF） of the two groups were significantly improved (all P＜0.05), and the changes were more obvious in the study group (P＜0.05). After discharge, the traditional Chinese medical syndrome scores of the two groups were increased, with the increase more significant in the study group (all P＜0.05). There was no significant adverse reaction in both groups. ConclusionYiqi Huoxue decoction can improve cardiac function and the long-term life quality of convalescent in coronary heart disease patients after PCI.
