Abstract

Objectives: The objective of this study investigated the relation between QT-dispersion (QTd) and both number of coronary artery disease and major adverse cardiovascular events (MACEs) among patients with type 2 diabetes after elective percutaneous coronary intervention (PCI). Methods: One hundred ischemic heart disease patients undergoing elective coronary angioplasty were included; 49 patients with diabetes (group I) and 51 patients without diabetes mellitus (group II). Based on the QTd parameter after PCI, both groups were subdivided into tertiles. Angiographic, electrocardiographic parameters, and MACE were compared. Results: Both QTd after PCI and delta QTd were correlated to the number of diseased coronary arteries and MACE in patients with diabetes compared to patients without diabetes. QTd was longer in patients with diabetes developing MACE than those without MACE (r = −0.31, P = 0.04). Conclusion: QTd after PCI and delta QTd are the independent predictors of MACE in patients with type 2 diabetes.

2型糖尿病患者经皮冠状动脉介入治疗后qt离散度及主要不良心血管事件预测

目的:探讨2型糖尿病患者择期经皮冠状动脉介入治疗(PCI)后qt离散度(QTd)与冠状动脉疾病数量和主要不良心血管事件(mace)的关系。方法:择期行冠状动脉成形术的缺血性心脏病患者100例;糖尿病患者49例(I组)，非糖尿病患者51例(II组)。根据PCI术后QTd参数将两组再细分为各组。比较血管造影、心电图参数和MACE。结果:与非糖尿病患者相比，糖尿病患者PCI术后QTd和δ QTd均与冠脉病变数和MACE相关。发生MACE的糖尿病患者的QTd比未发生MACE的糖尿病患者更长(r = - 0.31, P = 0.04)。结论:PCI术后QTd和δ QTd是2型糖尿病患者MACE的独立预测因子。
