[Assessment of life quality in patients with chronic heart failure].

Abstract

OBJECTIVE:

Using Kansas city cardiomyopathy questionnaire (KCCQ) to evaluate the quality of life (QOL) of the patients with chronic heart failure.

METHODS:

A total of 271 hospitalized patients with heart failure symptoms in cardiology department, Peking Union Medical College Hospital, who undergone coronary angiography from December 2007 to December 2008, were included in this study. QOL of the subjects was measured, and their demographic and clinical data were collected. Patients were divided into 2 groups according to heart function and they were compared by QOL.Multiple linear regression analysis was conducted to identify the variables associated with the quality of life.

RESULTS:

KCCQ physical limitation scores of the patients of left ventricular elective fraction (LVEF) < 50% (n = 50) and LVEF > or = 50% (n = 221) were (66 +/- 22) points and (73 +/- 22) points (P < 0.05). In the patients of NYHA I/II (n = 227) vs NYHA III/IV (n = 44), KCCQ scores of physical limitation, symptoms and QOL were (74 +/- 20) vs (60 +/- 27) points, (62 +/- 22) vs (49 +/- 25) points and (61 +/- 16) vs (53 +/- 18) points (all P < 0.05). In the patients of heart failure grade A/B (n = 197) vs grade C/D (n = 74), KCCQ scores of physical limitation, symptoms and QOL were (75 +/- 19) vs (61 +/- 26) points, (63 +/- 22) vs (52 +/- 24) points, (61 +/- 16) vs (56 +/- 18) points (all P < 0.05). Multiple linear regression analysis of QOL KCCQ showed that, age, NYHA cardiac function classification, gender and Judkins score were the risk factors of patients' physical limitation (P < 0.01); gender and stages of heart failure were the risk factors of patients'symptoms (P < 0.01); gender was the risk factors of patients'social function (P < 0.01).

CONCLUSION:

The patients with poor cardiac function have a poor QOL. KCCQ is more sensitive for the evaluation of heart function. Age, NYHA, gender, Judkins score and stages of heart failure can change QOL for the patients with chronic heart failure.
