背景:缺血性心脏病(IC)的定义并不总是很明确,这也正是要提出基于预后和冠心病(CAD)程度的新标准的原因。本研究中,作者评估了延迟钆增强心血管磁共振(CM R)对根据以往报道标准所确定IC的预测效能。方法和结果:123例心力衰竭(H F)、左室(LV)收缩功能障碍患者接受延迟钆增强CM R和冠状动脉造影检查,其中37例(30%)患者分入IC组,86例(70%)分入非IC组。IC组中94%的患者(35/37)可见心内膜下延迟钆增强(LGE),而在非IC组仅见于14%的患者(12/86)(P<0.001)。
Background: The definition of ischemic heart disease (IC) is not always clear and it is precisely the reason why new criteria based on prognosis and degree of coronary heart disease (CAD) are to be proposed. In this study, we evaluated the predictive power of delayed gadolinium-enhanced cardiovascular resonance (CM R) against ICs based on previously reported criteria. Methods and Results 123 patients with congestive heart failure (HF) and left ventricular (LV) systolic dysfunction underwent delayed gadolinium-enhanced CM R and coronary angiography. Thirty-seven patients (30% %) Into non-IC group. 94% of patients in the IC group (35/37) showed delayed subendocardial gadolinium enhancement (LGE) compared to 14% (12/86) in the non-IC group (P <0.001).
