Implication

May support reduced DASI for functional assessment in chronic coronary patients; leaves open need for prospective validation before adoption.

Structured PICO

Is the reduced version of the Duke Activity Status Index (DASI) reliable, valid, and responsive to clinical change in chronic coronary patients?

P
Population
90 chronic coronary patients, comprising 46 stable coronary heart disease outpatients and 44 patients undergoing elective angioplasty for angina pectoris.
I
Intervention
Administration of the reduced version of the Duke Activity Status Index (DASI)
O
Outcome
Reliability (Cronbach's alpha), validity (correlation with CCS grade and exercise test duration), and responsiveness to clinical change (effect size after angioplasty) of the reduced DASIpatient reported

The reduced version of the Duke Activity Status Index (DASI) is a reliable, valid, and responsive tool for assessing self-reported functional capacity in chronic coronary patients.
