摘要: 心肌细胞的钙稳态依赖于质膜、肌/内质网(SR)、线粒体等对钙(Ca2+)转运的调节。胞质钙超载、SR钙渗漏等在内的钙稳态失调,使心肌细胞钙瞬变减低,收缩力下降是心力衰竭的主要特征之一。

关键词: 钙稳态, 心力衰竭, 钙ATP酶2a, 2型兰尼碱受体(RyR2)

Abstract: Calcium homeostasis of cardiomyocytes depends on the regulation of calcium(Ca2+) transportation through plasma membrane, sarco/endoplasmic reticulum(SR) and mitochondria. One of the main characteristics of heart failure is calcium homeostasis, including cytosolic calcium overload and SR calcium leakage, which leads to transient decrease of myocardial calcium and decrease of contractility.

Key words: calcium homeostasis, heart failure, calcium ATPase 2a, ryanodine receptor 2(RyR2)
