| 摘 要： | 目的探讨冠状动脉介入治疗对不稳定型心绞痛(UA)患者QT离散度(QTd)及校正QT离散度(QTcd)的影响。方法206例经冠状动脉造影(CAG)确诊的UA患者,冠状动脉狭窄≥75%者94例(观察组)行经皮腔内冠状动脉成形术(PTCA)及支架术,CAG轻度狭窄50%~70%者108例为对照组,观察2组QTd及QTcd。结果CAG前后QTd及QTcd无显著差异(P>0.05),冠状动脉介入治疗后QTd及QTcd较治疗前明显缩短(P<0.05)。结论冠状动脉介入治疗能明显缩短QTd及QTcd,有利改善UA患者的预后。 |

| Abstract: | Objective To observe the effect of percutaneous coronary intervention(PCI) on QT dispersion(QTd) and correct QT dispersion(QTcd) in patients with unstable angina(UA).Methods Two hundreds and six patients with UA diagnosed by coronary angiography(CAG) were divided into two groups,94 patents with coronary stenosis over 70% were performed with percutaneous transluminal coronary angioplasty and stenting in observation group,108 patients with coronary stenosis 50%~75% were as control group.QTd and QTcd were observed in two groups.Results There was no difference in QTd and QTcd in control group pre-and post-CAG(P>0.05),but QTd and QTcd were shortened obviously in observation group after PCI.Conclusion PCI can improve the prognosis of patients with UA by shortening QTd and QTcd. |
