RESUMEN
Objective:To study therapeutic effect of Guanxintongluo (GXTL ) capsule combined dual antiplatelet drugs on prevention and treatment of in -stent restenosis after percutaneous coronary intervention (PCI) .Methods :A total of 82 patients with coronary heart disease undergoing stent implantation treated in our hospital were select‐ed .All patients were numbered ,and they were divided into dual antiplatelet group (n=40) and combined treatment group (n=42 ,received GXTL capsule based on dual antiplatelet group ) according to odd and even number method . Therapeutic effect was compared between two groups .Results:Compared with dual antiplatelet group after treat‐ment ,there were significant rise in total effective rates of in -stent restenosis (77.5% vs .95.2% ) ,angina pectoris (80.0% vs .95.2% ) ,ECG (77.5% vs .92.9% ) and syndrome of traditional Chinese medicine (72.5% vs .90.5% ) in combined treatment group , P0.05. Conclusion:Guanxintongluo capsule combined dual antiplatelet drugs can effectively reduce incidence rate of restenosis , improve syndrome of traditional Chinese medicine ,ECG chan‐ges ,reduce pain degree of angina pectoris in patients with coronary heart disease after PCI , which is worth extending .
