Abstract:
:Compared to the general population, elderly patients with cardiovascular disease have a higher prevalence of sarcopenia, and it shows an association with increased mortality risk. Although several studies have indicated that atherosclerosis may cause sarcopenia in community dwelling elderly subjects, the association between sarcopenia and atherosclerosis is not clear in patients with ischemic heart disease (IHD). The present study was performed to examine the association between muscle function and atherosclerosis in elderly patients with IHD. We reviewed the findings of 321 consecutive patients ≥ 65 years old with IHD. Three measures of muscle function were examined, i.e., gait speed, quadriceps isometric strength, and handgrip strength, just before hospital discharge. In addition, we measured intima-media thickness (IMT) as a parameter of arteriosclerosis. To investigate the association between sarcopenia and atherosclerosis, patients were divided into Group H (high), Group M (middle), and Group L (low) according to the tertiles of muscle function, and IMT was compared between the three groups. In addition, we considered the association between IMT thickening and muscle function. The mean age of the study population was 74.1 ± 6.0 years and 73.2% of the patients were men. IMT was compared between groups stratified according to gait speed and quadriceps isometric strength, and the results indicated that IMT was significantly lower in Group H than in Groups L and M (p < 0.05). In addition, gait speed and quadriceps isometric strength were associated with IMT thickening (p < 0.05). Parameters reflecting muscle function of the lower limbs are associated with atherosclerosis in patients with IHD.
