The following is a summary of “Prognostic value of the duke activity Status Index Questionnaire in predicting mortality in patients with chronic heart failure: 36-month follow-up study,” published in the October 2024 issue of Cardiology by Santos-de-Araújo et al.
The Duke Activity Status Index (DASI) questionnaire is widely used to assess physical functioning and has shown prognostic value in patients with chronic heart failure (CHF).
Researchers conducted a prospective cohort study determining optimal DASI thresholds for predicting mortality in patients with CHF.
They conducted a cohort study with a follow-up period of 36 months in patients with CHF. All patients underwent a clinical assessment, which included the DASI questionnaire, pulmonary function tests, and echocardiography. The Receiver Operating Characteristic (ROC) curve analysis assessed the DASI questionnaire score’s ability to predict mortality risk. For survival analysis, the Kaplan-Meier model examined the effects of scores ≤/> 23 points on mortality during the 36-month follow-up period.
The results showed that 1,024 patients, with most being older men. Kaplan-Meier analysis revealed that a score of ≤/>23 was a strong predictor of CHF mortality over a 36-month follow-up.
They concluded that a ≤/>23 score effectively predicted mortality risk in patients with CHF, particularly among those with lowered or mildly reduced ejection fraction.
