RESUMO
AIMS: Impairment in activities of daily living (ADL) is an independent predictor of poor prognosis in older patients. Nevertheless, the effects of instrumental ADL (IADL) frequency on prognosis in older patients with cardiovascular disease (CVD) are unclear. We investigate the associations between IADL frequency and all-cause mortality and hospital readmission due to cardiovascular events in older patients with CVD. METHODS AND RESULTS: A total of 638 consecutive outpatients ≥65 years old with CVD were enrolled. A questionnaire, including Frenchay Activities Index (FAI) parameters, was used to determine IADL frequency at the start of the study as the baseline observation. The primary endpoint was all-cause mortality, and the secondary endpoint was readmission for cardiovascular events. We examined the relationship between IADL frequency and each endpoint. Among the 632 patients evaluated {median age 74.0 [interquartile range (IQR) 70.0-78.0] years; 439 males}, there were 39 deaths and 105 cardiovascular events during the median follow-up period of 4.0 (IQR, 2.3-4.0) years. After adjusting for clinical confounding factors, the hazard ratios for all-cause mortality and cardiovascular events in the FAI points were 0.957 [95% confidence interval (CI), 0.920-0.996] and 0.973 (95% CI, 0.950-0.997), respectively. CONCLUSION: A higher IADL frequency was independently associated with better outcomes in older patients with CVD, suggesting that the preservation of instrumental activities should be focused on as the components of cardiovascular rehabilitation.

Although instrumental activities of daily living (IADL) are included in the outcomes of cardiac rehabilitation (CR), the relationship between IADL frequency at the end of CR and outcomes between the sexes remains unclear. We aimed to investigate the differences in frequency of IADL between the sexes and its impact on the outcomes. We retrospectively investigated 490 consecutive patients who were admitted for heart failure (HF) and participated in CR post-discharge. IADL frequency was assessed using the questionnaire-based Frenchay Activities Index (FAI). The primary endpoint was all-cause death, and the secondary endpoint was a composite of all-cause death and readmission due to HF. The cut-off values of the FAI for all-cause death in the overall cohort, females, and males were 23, 22, and 23 points, respectively. After adjusting for several factors, IADL assessed using the FAI was independently associated with all-cause mortality (hazard ratio [HR]: 0.961, 95% confidence interval [CI]: 0.937-0.986) and combined events (HR: 0.968, 95% CI: 0.952-0.985), respectively. Additionally, there was no interaction between sex and all-cause mortality. In conclusion, higher IADL frequency after CR was associated with favourable outcomes in patients with HF.

Left ventricular dysfunction is a pathophysiologic characteristic of heart failure. Impaired instrumental activities of daily living are associated with an elevated risk of mortality and heart failure in older adults. Nevertheless, the relationship between these activities and left ventricular function changes remains unclear. We determined whether instrumental activities of daily living are associated with subsequent left ventricular function changes in older cardiovascular disease patients. This retrospective cohort study included 383 outpatients with cardiovascular disease (74.5 ± 5.3 years, 273 males). Patients were divided according to the Frenchay activities index tertile and followed for six months after cardiovascular disease diagnosis. The left ventricular ejection fraction and annular early diastolic velocity (e') were measured for left ventricular systolic and diastolic function, respectively, at baseline and after one year. After adjusting for confounders, changes in the left ventricular ejection fraction were not significantly different. However, changes in the e' in the highest tertile group were significantly greater than in other groups. In the general linear model with multiple regression analysis, Frenchay activities index independently predicted the absolute change in the e'. In older cardiovascular disease patients, higher instrumental activities of daily living were associated with preserved left ventricular relaxation.

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.

OBJECTIVES: Although skeletal muscle density (SMD) is useful for predicting mortality, the cut-off in an acute clinical setting is unclear, especially in patients with cardiovascular disease (CVD). This study was performed to determine the preoperative SMD cut-off using the psoas muscle and to investigate the effect on postoperative outcomes, including sarcopaenia, in CVD patients. METHODS: Preoperative psoas SMD was measured by abdominal computed tomography in CVD patients. Postoperative sarcopaenia was defined according to the criteria of the Asia Working Group for Sarcopaenia. The Youden index was used to test the predictive accuracy of survival models. The prognostic capability was evaluated using multivariable survival and receiver operating characteristic curve analyses. RESULTS: Continuous data were available for 1068 patients (mean age 65.5 years; 63.6% male). A total of 105 (9.8%) deaths occurred during the 1.99-year median follow-up period (interquartile range 0.71-4.15). The psoas SMD cut-off estimated by the Youden index was 45 Hounsfield units with high sensitivity and moderate specificity for all-cause mortality and was consistent in various stratified analyses. After adjusting for the existing prognostic model, EuroSCORE II, preoperative and postoperative physical status, psoas SMD cut-off was predicted for mortality (hazard ratio 2.42, 95% confidence interval 1.32-4.45). The psoas SMD cut-off was also significantly associated with postoperative sarcopaenia and provided additional prognostic information to EuroSCORE II on receiver operating characteristic curve analysis (area under the curve 0.627 vs 0.678, P = 0.011). CONCLUSIONS: Reduced psoas SMD was associated with postoperative mortality and added information prognostic for mortality to the existing prognostic model in CVD patients.
