Abstract

Background: Cardiovascular disease (CVD) has become the leading cause of death worldwide. High muscle mass can reduce the incidence and mortality of CVD. In recent years, increasing attention has been given to the relationship between intrinsic capacity (IC) and CVD. This study aims to explore the relationship between the decline of IC, muscle strength, and muscle quality in older patients with CVD, providing a new method and basis for early recognition of IC decline in the older adults.

Methods: This cross-sectional study included 475 older individuals from communities in Zhejiang. General data were collected, and a comprehensive geriatric assessment (CGA) was conducted. Participants with CVD were divided into three groups: IC retention, IC impairment, and IC significantly impaired. Bioelectrical impedance analysis (BIA) measurements were completed. Student's t-test or non-parametric tests (Mann-Whitney) were used to analyze the correlation between IC and muscle-related indicators. The best cutoff values were obtained using ROC curve analysis.

Results: Compared to non-CVD patients, CVD patients were older, more educated, and had higher rates of polypharmacy and comorbidity. IC decreased more significantly in CVD patients. Age (P=0.001), Fried (P=0.024), and GDS-5 (P=0.002) increased with the severity of IC decline. ADL (P=0.002), MMSE (P=0.000), MNA-SF (P=0.000), SARC-Calf (P=0.026), waist circumference (P=0.037), and muscle quality (P=0.010) decreased with the decline in IC. When IC decreased, the cutoff values for hand grip strength, waist circumference, and muscle quality were 25.45 kg, 72.55 cm, and 3.05, respectively. When IC decreased significantly, the cutoff values were 17.15 kg, 71.55 cm, and 2.28, respectively.

Conclusion: The results of this study showed that in patients with CVD, the hand grip strength and muscle quality of patients with IC injury were lower than those of patients with IC retention.

老年心血管疾病患者内在能力与肌肉力量和质量之间的相关性：一项横断面研究

背景：心血管疾病（CVD）已成为全球死亡的主要原因。高肌肉质量可降低心血管疾病的发病率和死亡率。近年来，人们越来越关注内在能力（IC）与心血管疾病之间的关系。本研究旨在探讨心血管疾病老年患者的内在能力下降、肌肉力量和肌肉质量之间的关系，为早期识别老年人的内在能力下降提供新的方法和依据：方法：本横断面研究纳入了浙江省 475 名社区老年人。方法：这项横断面研究纳入了浙江省 475 名社区老年人，收集了他们的一般资料，并进行了老年综合评估（CGA）。患有心血管疾病的参与者被分为三组：IC保留组、IC受损组和IC明显受损组。完成了生物电阻抗分析（BIA）测量。采用学生 t 检验或非参数检验（曼-惠特尼）分析 IC 与肌肉相关指标之间的相关性。通过 ROC 曲线分析得出最佳临界值：与非心血管疾病患者相比，心血管疾病患者年龄更大、受教育程度更高、多药并发症发生率更高。心血管疾病患者的 IC 下降更为明显。年龄（P=0.001）、Fried（P=0.024）和GDS-5（P=0.002）随IC下降的严重程度而增加。ADL（P=0.002）、MMSE（P=0.000）、MNA-SF（P=0.000）、SARC-Calf（P=0.026）、腰围（P=0.037）和肌肉质量（P=0.010）随着 IC 的下降而下降。当 IC 下降时，手握力、腰围和肌肉质量的临界值分别为 25.45 千克、72.55 厘米和 3.05。当 IC 明显下降时，临界值分别为 17.15 千克、71.55 厘米和 2.28：研究结果表明，在心血管疾病患者中，IC损伤患者的手握力和肌肉质量均低于IC保留患者。

期刊介绍： Clinical Interventions in Aging, is an online, peer reviewed, open access journal focusing on concise rapid reporting of original research and reviews in aging. Special attention will be given to papers reporting on actual or potential clinical applications leading to improved prevention or treatment of disease or a greater understanding of pathological processes that result from maladaptive changes in the body associated with aging. This journal is directed at a wide array of scientists, engineers, pharmacists, pharmacologists and clinical specialists wishing to maintain an up to date knowledge of this exciting and emerging field.
