Key result
Tissue Doppler imaging-derived ejection time (RR 0.80; 95% CI 0.71-0.90; P<0.001) and systolic time significantly predicted the risk of rehospitalization in patients with chronic heart failure.
Why the study?
Do tissue Doppler imaging time intervals predict rehospitalization in patients with chronic heart failure?
Cohort (n=249)
Do tissue Doppler imaging time intervals predict rehospitalization in patients with chronic heart failure?
Effect estimate: RR 0.80 (95% CI 0.71-0.90)
p-value: p=<0.001
Tissue Doppler imaging-derived time intervals, specifically ejection time and systolic time, can help predict the risk of rehospitalization in patients with chronic heart failure.

May aid rehospitalization risk stratification in chronic HF; leaves open prospective validation before clinical use.
Correale et al. (2012) conducted a cohort in chronic heart failure (n=249). Tissue Doppler imaging (TDI) time intervals was evaluated on occurrence of rehospitalization (RR 0.80, 95% CI 0.71-0.90, p=<0.001). Tissue Doppler imaging-derived ejection time (RR 0.80; 95% CI 0.71-0.90; P<0.001) and systolic time significantly predicted the risk of rehospitalization in patients with chronic heart failure.
