Objective:To investigate the therapeutic effect of comprehensive geriatric assessment(CGA) in elderly patients with chronic heart failure(CHF) complicated with sarcopenia, and to provide a theoretical reference for clinical application.Methods:This study was a prospective randomized controlled study. 110 elderly CHF patients with myopenia admitted to the Third People's Hospital of Hefei from January 2019 to February 2022 were selected. Using the random number table method, 56 cases were divided into an observation group and 54 cases into a control group. Before treatment, the control group of patients underwent a selective single assessment based on the hospital's requirements and the patient's actual situation, including a fall risk assessment, nutritional risk screening checklist assessment, and routine medication to improve cardiac function and prognosis; Before treatment, the patients in the observation group were assessed with CGA, including the assessment of physical function, mental and psychological status, multiple drug management, pain, Sleep disorder, and social environment. According to the assessment results, individual diagnosis and treatment plans were formulated, implemented, and dynamically adjusted. The two groups were treated for 12 weeks. The general information, treatment compliance, B-type brain natriuretic peptide (BNP) level, left ventricular Ejection fraction (LVEF), 6 min walking distance (6MWD), arm strength of upper limbs and 6 m walking speed, clinical efficacy and prognosis of the two groups were compared before and after treatment. The measurement data is represented by xˉ± s, group t-tests are used for inter group comparison, and paired t-tests are used for intra group comparison before and after treatment; Counting data is represented as an example (%), and inter group comparisons are made using χ 2 test, non parametric rank sum test was used for inter group comparison of hierarchical data. Results:There was no statistically significant difference in gender, age, course of CHF, smoking, alcohol consumption, number of comorbidities, cardiac function grading, and treatment compliance between the two groups of patients (all P>0.05), indicating comparability. Before treatment, there was no statistically significant difference in plasma BNP, LVEF, 6MWD, upper limb grip strength, and 6-meter walking speed between the two groups of patients (all P>0.05); After treatment, the BNP of both groups of patients was lower than before treatment and the observation group was lower than the control group. LVEF, 6MWD, upper limb grip strength, and 6-meter walking speed were all higher than before treatment and the observation group was higher than the control group [(343.45±34.95) ng/L vs (387.09±46.96) ng/L, (49.61±7.11)% vs (42.94±5.72)%, (348.92±37.73) m vs (297.74±43.48) m, (22.64±3.82) kg vs (19.48±3.88) kg, (0.97±0.10) m/s vs (0.83±0.12) m/s], The differences were statistically significant ( t-values were 5.51, -5.40, -6.60, -4.31, -6.60, all P<0.001). After 12 weeks of treatment, there was no statistically significant difference in clinical efficacy between the two groups of patients ( P=0.216), but the overall poor prognosis rate in the follow-up observation group was lower than that in the control group [7.14%(4/56) vs 22.22% (12/54)], and the difference was statistically significant (χ 2=5.03, P=0.025). Conclusions:Developing, implementing, and dynamically adjusting the individualized treatment plan involving CGA can improve the prognosis of elderly CHF patients with sarcopenia, help improve cardiac function, increase grip strength and somatic function, and reduce the risk of major adverse cardiovascular events ,all-cause mortality in elderly patients with CHF combined with sarcopeni and has certain clinical application value.
