Chronic heart failure (CHF) is a major and growing problem in the western hemisphere, affecting about 5 million patients in the United States. In daily practice patients with left ventricular systolic dysfunction (LVSD) and significant angiographic coronary artery disease (CAD) are felt to have an ischemic cardiomyopathy (ICMP) and those without CAD or mild-moderate CAD out of proportion to the extent of LVSD are felt to have a non-ischemic cardiomyopathy (NICMP). Although invasive coronary angiography is the gold standard for the diagnosis of CAD, recent advances in non-invasive imaging have created multiple options for evaluating ICMP and NICMP. This review details the role of cardiac imaging in the diagnosis of ICMP and NICMP and outlines an algorithm of use of non-invasive tests in asymtomatic LVSD and symptomatic heart failure.
慢性心力衰竭（CHF）是西半球的一个主要且不断增长的问题，影响了美国约 500 万患者。在日常实践中，左心室收缩功能障碍（LVSD）和明显的血管造影冠状动脉疾病（CAD）的患者被认为患有缺血性心肌病（ICMP），而没有 CAD 或 CAD 程度与 LVSD 不成比例的轻度至中度 CAD 的患者被认为患有非缺血性心肌病（NICMP）。虽然有创冠状动脉造影是 CAD 诊断的金标准，但非侵入性成像的最新进展为评估 ICMP 和 NICMP 提供了多种选择。本综述详细介绍了心脏成像在诊断 ICMP 和 NICMP 中的作用，并概述了在无症状 LVSD 和有症状心力衰竭中使用非侵入性检查的算法。
