Myocardial Viability: From PARR-2 to IMAGE HF - Current Evidence and Future Directions

Abstract Ischemic heart failure is a growing disease with high morbidity and mortality. Several studies suggest the benefit of viability imaging to assist revascularization decision, but there is controversy. Multiple imaging modalities can be used to accurately define hibernating myocardium; however, the best approach remains uncertain. This review will highlight current evidence and future directions of viability imaging assessment.

摘要：缺血性心力衰竭（ischemic heart failure）是一类发病率与死亡率均居高不下的高发疾病。多项研究表明，存活心肌成像（viability imaging）有助于辅助血运重建决策，但该领域仍存在诸多争议。目前已有多种成像模态（imaging modalities）可精准识别冬眠心肌（hibernating myocardium），但最佳评估方案仍未明确。本综述将重点梳理当前存活心肌成像评估的相关证据，并展望其未来发展方向。
