Key result
An ejection fraction <40% or a deceleration time <200 msec correctly predicted the development of congestive heart failure in 60 of 62 patients following a first myocardial infarction.
Why the study?
Do early echocardiographic parameters (EF, transmitral filling, IMP) predict the development of congestive heart failure following a first myocardial infarction?
Population
109 patients admitted for their first acute myocardial infarction who underwent two-dimensional and Doppler…

May stratify post-MI HF risk via early EF and DT; hypothesis-generating and requires prospective validation before practice change.

p-value: p=<0.001
Early echocardiographic assessment of ejection fraction and diastolic filling parameters (such as deceleration time) strongly predicts the development of congestive heart failure after a first myocardial infarction.
Steven J. Lavine (2003) conducted an observational in first acute myocardial infarction (n=109). Ejection fraction < 40% or deceleration time < 200 msec vs. Ejection fraction ≥ 40% or deceleration time ≥ 200 msec was evaluated on Development of congestive heart failure (p=<0.001). An ejection fraction <40% or a deceleration time <200 msec correctly predicted the development of congestive heart failure in 60 of 62 patients following a first myocardial infarction.
