Why the study?
Does restrictive diastolic filling on Doppler echocardiography predict survival in patients with cardiac amyloidosis?
Does restrictive diastolic filling on Doppler echocardiography predict survival in patients with cardiac amyloidosis?
Doppler-derived restrictive diastolic filling patterns (deceleration time ≤150 msec) strongly predict 1-year mortality in patients with cardiac amyloidosis.
No takes yet. Share an insight, caveat, or question.
Short deceleration time may aid mortality risk stratification in cardiac amyloidosis; leaves open whether it guides therapy in prospective studies.
Klein et al. (1991) studied this question.
