Heart failure is a clinical diagnosis that is supported by various laboratory, imaging, and invasive hemodynamic measures. There is no single diagnostic test. A variety of structural and/or functional myocardial abnormalities can lead to the inability of the heart to fill or eject blood. Despite ejection fraction being the most commonly assessed measure of systolic function in clinical practice, it is a poor measure of contractility because it is susceptible to loading conditions and chamber size. Invasive hemodynamic assessment remains of great importance in the evaluation of patients with myocardial disease or hypertrophic cardiomyopathy.
心力衰竭是一种临床诊断，需要各种实验室、影像学和有创血流动力学检查来支持。没有单一的诊断测试。多种结构和/或功能性心肌异常可导致心脏无法充盈或射血。尽管射血分数是临床实践中评估收缩功能最常用的指标，但它作为收缩性的指标并不可靠，因为它易受负荷情况和心腔大小的影响。有创血流动力学评估在心肌病或肥厚型心肌病患者的评估中仍然非常重要。
