Systolic and diastolic heart failure are the 2 most common clinical subsets of chronic heart failure. Left ventricular "Starling" function is depressed in patients with systolic heart failure. In systolic heart failure, left ventricular mass is increased, which can be measured by transthoracic echocardiography. Cardiac magnetic resonance imaging is a more precise technique to measure left ventricular mass. Neurohormonal activation is a major pathophysiologic mechanism for ventricular remodeling and progression of heart failure in systolic heart failure.
收缩性和舒张性心力衰竭是慢性心力衰竭的 2 种最常见临床亚型。收缩性心力衰竭患者的左心室“Starling”功能受到抑制。在收缩性心力衰竭中，左心室质量增加，可以通过经胸超声心动图测量。心脏磁共振成像（cardiac magnetic resonance imaging）是一种更精确的测量左心室质量的技术。神经激素激活是心室重构和心力衰竭进展的主要病理生理机制。
