Abstract：Objective To investigate the factors affecting the decline of grip strength in elderly patients with coronary heart disease in Critical Care Unit(CCU).Methods From January 2023 to February 2024,86 elderly patients with coronary heart disease(CHD)in CCU were selected.The grip strength level of all patients was meas-ured,.The influencing factors of the decline of grip strength were analyzed by univariate and multiple linear regres-sion.Results All patients had grip strength levels ranging from 5.6 to 32.4 kg,with an average grip strength level of(13.68±3.37)kg.Univariate analysis revealed that grip strength levels were significantly lower in patients who were over 60 years old,female,had a body mass index(BMI)≤ 18.5 kg/m2,albumin levels ≤ 22 g/L,a dis-ease course of over 10 years,a history of smoking,a history of alcohol consumption,an APACHE Ⅱ score＞22,and not engaged in resistance training(P＜0.05).Among these,being over 60 years old,female,having a BMI ≤ 18.5 kg/m2,albumin levels≤22 g/L,a disease course of over 10 years,an APACHE Ⅱ score＞22,and not participating in resistance training were identified as independent factors affecting the decline in grip strength among elderly CCU patients(P＜0.05).Conclusion The decline in grip strength among elderly CCU patients is associated with multiple factors,including age,gender,body mass index,albumin levels,disease course,health status scores,and engagement in resistance training.The combined effect of these factors leads to muscle weakness,thereby affecting their grip strength levels.
