疏血通在防治冠脉内支架植入术后再狭窄中的作用

目的评价疏血通预防冠状动脉内支架植入术后再狭窄的作用。方法68例完成冠脉内支架植入术的患者在给予常规治疗的基础上，随机分为常规治疗对照组和疏血通治疗组。随访观察6个月，采用定量冠状动脉造影的方法对比观察两组患者冠脉病变的再狭窄情况。结果共有43例患者完成随访，疏血通治疗组23例，常规治疗组20例。疏血通治疗组心绞痛复发率[3例(13％)]明显低于常规治疗组[7例(35％)](P<0．05)。定量冠状动脉造影结果显示，疏血通治疗组经治血管的病变狭窄程度明显轻于常规治疗组；晚期丢失内径及其指数[(0．46±0．25)mm，(24．26±8．64)％]显著小于常规治疗组[(0．75±0．33)mm，(31．25±11．03)％]，P值均<0．05；而净获得内径及其指数[(1．23±0．30)mm，(58．96±24．68)％]明显大于常规治疗组[(0．98±0．33)mm，(42．68±29．51)％]，P值均<0．05。两组患者的再狭窄率比较无显著性差异(P>0．05)。结论疏血通在预防冠脉内支架植入术后再狭窄中可能具有一定作用。

Effect of Shuxuetong in Preventing Restenosis after Intracoronary Stenting

OBJECTIVE: To evaluate the effect of shuxuetong (SXT) in preventing restenosis after intracoronary stenting. METHODS: Sixty-eight patients, accepted intracoronary stenting, were divided into two groups, the SXT group and the control group, both of them were treated with conventional treatment, and to the SXT group, SXT was given additionally. The condition of treated coronary artery restenosis in the two groups was compared by way of quantitative coronary angiography and a 6-month follow-up study was adopted. RESULTS: Follow-up study was completed in 43 patients (23 cases in the SXT group, and 20 in the control group). The angina recurrence rate in the SXT group (3 cases, 13%) was significantly lower than that in the control group (7 cases, 35%, P < 0.05). Quantitative coronary angiography showed the restenosis degree of operated artery in the SXT group was significantly milder than that in the control group, with the last lumen losing and index in the SXT group (0.46 +/- 0.25 mm, 24.26 +/- 8.64%) less than those in the control group (0.75 +/- 0.33 mm, 31.25 +/- 11.03%). The net gain lumen and the net gain index in the SXT group (1.23 +/- 0.30 mm, 58.96 +/- 24.68%) were greater than those in the control group (0.98 +/- 0.33 mm, 42.68 +/- 29.51%), all P < 0.05. But the restenosis rate in the two groups was insignificantly different (P > 0.05). CONCLUSION: SXT might has some definite effect in preventing restenosis after intracoronary stenting.
