Key result
Serial Doppler echocardiography in severe heart failure showed good short-term reproducibility, with mean differences within 10% of the mean value for most parameters.

Supports short-term Doppler echo reliability for systolic assessment in severe HF; hypothesis-generating for diastolic indices and needs prospective validation.
Observational (n=26)
What is the reproducibility of Doppler indices of left ventricular systolic and diastolic function in patients with severe chronic heart failure?
Doppler echocardiography provides reproducible short-term and day-to-day measurements of systolic function in severe heart failure, though diastolic indices exhibit greater variability.
Pozzoli et al. (1995) conducted an observational in severe chronic heart failure (n=26). Serial Doppler echocardiography was evaluated on Short-term intra- and inter-observer, mid-term and day-to-day variabilities of Doppler indices. Serial Doppler echocardiography in severe heart failure showed good short-term reproducibility, with mean differences within 10% of the mean value for most parameters.
