目标:

骨骼肌质量和心脏结构随年龄增长而变化。目前尚不清楚骨骼肌质量（SMM）的减少是否伴随心脏质量的下降。本研究旨在探讨老年住院患者中左心室质量（LVM）与肌少症及其严重程度之间的关系。

方法:

本研究共纳入71名肌少症受试者和103名非肌少症对照者。采用生物电阻抗分析、握力测试和5次起坐测试分别评估骨骼肌质量（SMM）、肌肉力量和身体功能。通过超声心动图评估心肌结构和功能。肌少症的诊断依据2019年亚洲肌少症工作组标准。

结果:

肌少症患者的左心室尺寸和左心室质量（LVM）均小于非肌少症对照组。重度肌少症患者的左心室尺寸和LVM均小于非重度肌少症患者。在单变量回归分析中，体重指数（BMI）、心脏大小和LVM与骨骼肌质量（SMM）或骨骼肌指数（SMI）呈正相关。在多变量回归分析中，BMI和LVM与SMM和SMI独立相关。LVM与BMI联合检测预测肌少症的敏感性为66.0%，特异性为88.7%（AUC：0.825；95% CI：(0.761, 0.889)）；p< 0.001。

结论:

在住院的老年患者中，左心室质量降低与肌肉减少症及其严重程度相关，而左心室质量与体重指数的联合检测对肌肉减少症具有预测价值。

Bone Disorders

Bone Disorders

Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

Imbalances in Cardiac Output

Imbalances in Cardiac Output

The heart's primary function is to pump blood throughout the body, maintaining a balance between blood sent out (cardiac output) and blood returning (venous return). If this balance is disrupted, it can result in congestive heart failure (CHF), a severe condition where the heart becomes an inefficient pump, leading to inadequate blood circulation.
CHF can occur due to the failure of either side of the heart. Left-side failure leads to pulmonary congestion—the right side continues to send...
