目的 探討銀杏葉膠囊聯(lián)合通脈口服液治療冠心病經(jīng)皮冠狀動(dòng)脈介入術(shù)（PCI）術(shù)后再狹窄的臨床療效。方法 選取2016年12月-2017年3月成都市第三人民醫(yī)院收治的冠心病PCI術(shù)后患者64例，將所有患者隨機(jī)分為對(duì)照組和治療組，每組各32例。對(duì)照組口服通脈口服液，1支/次，2次/d。治療組在對(duì)照組基礎(chǔ)上口服銀杏葉膠囊，1~2粒/次，3次/d。兩組患者均連續(xù)治療1個(gè)月。觀察兩組的臨床療效，比較兩組的再狹窄情況。結(jié)果 治療后，對(duì)照組和治療組的臨床癥狀療效的總有效率分別為78.1%、96.9%，兩組比較差異有統(tǒng)計(jì)學(xué)意義（P<0.05）。治療后，對(duì)照組和治療組的心電圖療效總有效率分別為71.9%、90.6%，兩組比較差異有統(tǒng)計(jì)學(xué)意義（P<0.05）。冠心病PCI術(shù)后3個(gè)月，對(duì)照組和治療組的再狹窄率分別為12.5%、6.3%，兩組比較差異有統(tǒng)計(jì)學(xué)意義（P<0.05）。結(jié)論 銀杏葉膠囊聯(lián)合通脈口服液治療冠心病PCI術(shù)后再狹窄具有較好的臨床療效，能降低冠心病PCI術(shù)后再狹窄，安全性較好，具有一定的臨床推廣應(yīng)用價(jià)值。

Objective To explore the clinical effect of Gingko biloba Leaves Capsules combined with Tongmai Oral Liquid in treatment of coronary restenosis after PCI. Methods Patients (64 cases) with coronary restenosis after PCI in the Third People's Hospital of Chengdu from December 2016 to March 2017 were randomly divided into control and treatment groups, and each group had 32 cases. Patients in the control group were po administered with Tongmai Oral Liquid, 1 bottle/time, twice daily. Patients in the treatment group were po administered with Gingko biloba Leaves Capsules on the basis of the control group, 1-2 grains/time, three times daily. Patients in two groups were treated for 1 month. After treatment, the clinical efficacies were evaluated, and the coronary restenosis in two groups were compared. Results After treatment, the clinical symptom efficacies in the control and treatment groups were 78.1% and 96.9%, respectively, and there was difference between two groups (P<0.05). After treatment, the electrocardiogram efficacies in the control and treatment groups were 71.9% and 90.6%, respectively, and there was difference between two groups (P<0.05). After PCI of coronary heart disease for 3 months, the coronary restenosis rates in the control and treatment groups were 12.5% and 6.3%, respectively, and there was difference between two groups (P<0.05). Conclusion Gingko biloba Leaves Capsules combined with Tongmai Oral Liquid has clinical curative effect in treatment of coronary restenosis after PCI, can decrease coronary restenosis after PCI, with good safety, which has a certain clinical application value.
