OBJECTIVE

To explore the clinical effectiveness of concentrated Xuefu Zhuyu Pill (CXZP) on restenosis (RS) of coronary heart disease (CHD) after intracoronary stenting.

METHODS

Eighty-four successful intracoronary stenting patients were randomly divided into conventional treatment group (control group, 41 cases) and conventional treatment plus CXZP group (treated group, 43 cases). The follow-up underwent for 6 months. Clinical symptom, change of blood stasis were observed. And occurrence of restenosis was estimated by ECG exercise treadmill testing, emission computed tomography (ECT) and coronary angiography (CAG).

RESULTS

The symptoms of blood stasis of treated group improved in the follow-up significantly (P < 0.01), and the integral of blood stasis were decreased significantly in the treated group vs the conventional treatment group (P < 0.01). The recurrent angina pectoris rate of the treated group was lower than the conventional treatment group (P < 0.01). The 61.9% of 84 patients reexamined the CAG in the follow up, and the lower restenosis rate (25.8%) in the treated group than in the conventional treatment group (32.1%, P = 0.59).

CONCLUSION

There is the trend that CXZP could prevent restenosis. Therefore, it is necessary to increase the cases for further study of CXZP on preventing restenosis.
