Assessment of quality of life in patients with chronic Keshan disease and analysis of its influencing factors / 中华地方病学杂志

ABSTRACT

Objective:To evaluate the quality of life of patients with chronic Keshan disease, and to explore related influencing factors, in order to provide a theoretical basis for improving the quality of life of patients with chronic Keshan disease.Methods:According to the standard of "Diagnosis of Keshan Disease" (WS/T 210-2011), 110 patients with chronic Keshan disease treated in the Jingchuan People's Hospital, Pingliang City, Gansu Province were selected as the research subjects, and demographic and disease data of the patients were collected by questionnaire survey; the quality of life of patients was assessed by the Minnesota living with heart failure questionnaire (MLHFQ); and correlation analysis was used to analyze and explore the influencing factors of patients' MLHFQ score.Results:Among the 110 patients with chronic Keshan disease, 66 were males and 44 were females, aged (60.93 ± 8.22) years; the education level was mainly junior high school or below, accounting for 92.73% (102/110); average annual family income was 20 700 yuan; the cardio-thoracic ratio of the patient was 0.64 ± 0.09; the ejection fraction (EF) was (36.71 ± 7.55)%; the labor ability classification was mainly based on simple activities, accounting for 60.91% (67/110); and the cardiac function classification was mainly Grade Ⅲ, accounting for 67.27% (74/110). The total MLHFQ scores of chronic Keshan patients were (69.17 ± 16.14) points, and the scores of physical, emotional and other fields were (26.32 ± 6.70), (15.86 ± 4.96) and (26.94 ± 6.10) points, respectively. The total MLHFQ scores had statistically significant differences among patients with different education level, cardio-thoracic ratio, EF, labor ability classification, cardiac function classification and annual family income ( F=7.121, 6.236, 4.515, 3.427, 5.418, Z=2.346 , P < 0.05). The results of correlation analysis showed that educational level and labor ability classification were negatively correlated with scores in physical field and other fields ( r=- 0.302, - 0.206, - 0.343, - 0.285, P < 0.01), and annual family income was negatively correlated with scores in emotional field ( r=- 0.263, P < 0.01). The cardiac function classification was positively correlated with scores in physical and other fields ( r=0.233, 0.210, P < 0.05). Conclusions:The quality of life of patients with chronic Keshan disease is poor. The quality of life of patients is affected by their educational level, annual family income, labor ability classification, cardiac function classification, etc.
