摘要
目的:探讨糖尿病(DM)合并冠心病(CHD)和单纯CHD患者在经皮腔内冠状动脉成形术(PTCA)前、后QT间期离散度(QTd、QTcd)的变化。方法:对选择性冠状动脉造影(CAG)阳性的196例单纯CHD与58例DM合并CHD患者进行PTCA,对PTCA术前和术后QTd、QTcd进行比较分析。结果:DM组与非DM组比较,PTCA术前QTd、QTcd显著增加(P<0.01);术后24h、7d、30d的QTd、QTcd无显著差异。结论:DM是影响CHD患者QTd、QTcd延长的因素之一;但PTCA是DM合并CHD患者降低QTd、QTcd安全、有效的方法。
Objective： To investigate the effect of percutaneous transluminal coronary angioplasty on QT dispertion in patients with coronary heart disease （CHD） with diabetes meUitus（DM） and CHD without DM. Methods ： PTCA was performed on total 254 patients including 58 patients with DM and 196 patients without DM . to observe the variety of QTd and QTcd between the performed on patients with DM and without DM. Results： Before PTCA there was significant difference in QTd and QTed between group DM and group NDM （P〈0. 01）. In 24hour, 7day, 30day post- operation there was no significant difference in QTd and QTcd between the two groups. Conclusion ： DM is one of the causes that can prolong QTd and QTcd. PTCA is an effective therapeutic method which can cut down QTd and QTcd for diabetic patients with coronary heart disease.
