Prognostic Value of Self-Reported Subjective Exercise Capacity in Patients With Acute Dyspnea
Authors' conclusion
Quantification of self-reported subjective exercise capacity using the DASI provides high prognostic accuracy and may aid physicians in risk stratification.
Study context
- Population
- Unselected patients presenting with acute dyspnea to the EDeligible for analysis
- Participants
- 1,019 patients
- Comparison
- Duke Activity Status Index (DASI) vs BNP for prognostic accuracy
- Outcome
- Prognostic accuracy (C-index) of DASI and BNP for all-cause mortality
- Follow-up
- 90 and 720 days
Performance
As reported in the abstract
720-day all-cause mortality by DASI quartile · 720 days
Hazard ratio (95% CI)
DASI Q1vs DASI Q4aHR 6.1 (95% CI 3.7-10.1)
9.1(5.5–14.9)
DASI Q2vs DASI Q4aHR 4.4 (95% CI 2.6-7.3)
6.4(3.9–10.6)
DASI Q3vs DASI Q4aHR 2.4 (95% CI 1.4-4.0)
3.2(1.9–5.5)
- 720-day mortality C-index, DASI vs BNP
- 0.67 vs 0.62; P = 0.024
- Deaths within 90 days
- 75 (7%)
- Deaths within 720 days
- 297 (29%)
