Acute myocardial infarction (AMI) results in significant changes in cardiac structure and functions, leading to left ventricular remodeling and subsequent systolic and diastolic dysfunction. To improve current approaches in diagnoses, treatments, and prevention of cardiovascular diseases, a better understanding of cardiac mechanoenergetics, including systolic performance and energy demand, becomes paramount. In this review, we summarize cardiac mechanics, cardiac energetics, and their relationship in complications related to AMI using 2 important physiologic frameworks, pressure-volume loops and the Vo-pressure-volume area relationship diagram, as they are powerful tools for understanding physiologic behavior and mechanoenergetics of the left ventricle.
急性心肌梗死（AMI）导致心脏结构和功能发生重大变化，导致左心室重构以及随后的收缩和舒张功能障碍。为了改善心血管疾病的诊断、治疗和预防现状，更好地理解心脏力学，包括收缩性能和能量需求，变得至关重要。在这篇综述中，我们使用 2 个重要的生理框架，即压力-容积环和 Vo-压力-容积面积关系图，总结了与 AMI 相关并发症中的心脏力学、心脏能量学及其关系，因为它们是理解左心室生理行为和力学的有力工具。
