扩张型心肌病(DCM)的特征是心脏功能恶化和左心室(或两个)收缩和扩张受损。血液标志物-被称为“生物标志物”,允许洞察潜在的病理生理机制和生物途径,同时预测结果和指导心力衰竭管理和/或治疗。在这篇综述中,我们提供了另一种方法来概念化心力衰竭生物标志物:心肌细胞,其周围的微环境,以及这些实体之间具有明确的相互作用的宏观环境,这些实体可能会影响参与DCM发病机制和/或传播的细胞过程。左心室收缩功能障碍的较新的生物标志物可分类为:(a)肌细胞应激和牵张,(B)肌细胞凋亡,(c)心肌梗死,(d)炎症,(e)氧化应激,(f)心脏能量学,(g)神经激素和(h)肾生物标志物。生物标志物提供了深入了解DCM的发病机制,同时预测并可能提供这些心力衰竭患者的预后信息。
Dilated cardiomyopathy (DCM) is characterized by deteriorating cardiac performance and impaired contraction and dilation of the left (or both) ventricles. Blood markers – known as “biomarkers” allow insight into underlying pathophysiologic mechanisms and biologic pathways, while predicting outcomes and guiding heart failure management and/or therapies. In this review, we provide an alternative approach to conceptualize heart failure biomarkers: the cardiomyocyte, its surrounding microenvironment, and the macroenvironment with clear interaction between these entities which may impact cellular processes involved in the pathogenesis and/or propagation of DCM. Newer biomarkers of left ventricular systolic dysfunction can be categorized under: (a) myocyte stress and stretch, (b) myocyte apoptosis, (c) cardiac interstitium, (d) inflammation, (e) oxidative stress, (f) cardiac energetics, (g) neurohormones and (h) renal biomarkers. Biomarkers provide insight into the pathogenesis of DCM while predicting and potentially providing prognostic information in these patients with heart failure.
