Aim
to evaluate the role of the DASI index in quality-of-life assessment in patients with atrial fibrillation and acute decompensation of chronic heart failure.
Material and methods
A prospective cohort study included 151 patients with nonvalvular AF who were hospitalized with an acute decompensation of chronic HF (mean age 75 ± 9.38 years, 56%). All patients underwent the quality-of-life assessment for quality of life using the Kansas (KCCQ-12) and Minnesota (MLHFQ) questionnaires, as well as Duke Activity Status Index (DASI) at admission.
Results
45.6% of patients with established AF had index of functional activity 0-20%, 39.3% had index 21-40%, 11.2% had index 41-60%, 2.6% had index 61-80%, and 1.3% had index 81-100%. Patients with DASI index 0-20% (0-11.64)) are characterized by a significant decrease in Kansas questionnaire parameters as physical limitations (32,0 versus 49,8 and 42,5,p<0,05), social limitations (34,2 versus 45,6 and 46,7, p<0,01), quality of life (27,7 versus 39,6 and 47,5, p<0,001) and clinical condition (27,1 versus 34,3 and 40,2, p<0,001), as well as a significant increase of parameter of Minnesota questionnaire(58,3 versus 54,1 and 40,2, p<0,01), which corresponds to a deterioration in quality of life in comparison with patients DASI 21-40% and DASI 41-60% respectively.
Conclusion
DASI index in patients with AF helps to identify patients with a low level of functional activity (DASI index (0-20% (0-11,64)), which have significantly worse quality of life parameters by the Kansas (KCCQ-12) and Minnesota (MLHFQ) questionnaires.
