Left ventricular dysfunction remains one of the best prognostic determinants of survival in patients with coronary artery disease. Revascularization has been shown to improve survival compared with medical therapy alone. Viability testing can help direct patients who will benefit the most from revascularization. Single-photon emission computed tomography, dobutamine stress echo, cardiac MRI, and PET imaging with F18-fluorodeoxyglucose are the most common modalities for assessing myocardial viability. Viability testing can help differentiate which patients benefit most from chronic total occlusion interventions.
左心室功能障碍仍然是冠心病患者生存的最佳预后决定因素之一。与单纯药物治疗相比，血运重建已被证明可提高生存率。存活心肌检测有助于指导哪些患者将从血运重建中获益最大。单光子发射计算机断层扫描、多巴酚丁胺负荷超声心动图、心脏磁共振成像以及使用F18-氟脱氧葡萄糖的正电子发射断层显像术是评估心肌存活的最常用方法。存活心肌检测有助于区分哪些患者从慢性完全闭塞干预中获益最大。
