Measurement of Ejection Fraction After Myocardial Infarction in the Population: Current Recommendations

While some studies reported that an approximate estimation of LVEF can be performed clinically in 40% of patients after MI, the practical value of such scoring systems is limited. Indeed, stud-ies reported associations between several clinical indicators and abnormal LVEF, but these studies consisted of relatively small case series and the proposed prediction algorithms were not validated independently. In the current guidelines for the management of patients with acute MI, the ACC and AHA strongly support the measurement of LVEF after MI and underscore the value of predischarge assessment of ventricular function for risk stratifi-cation.
Actual Frequency of LVEF Measurement After MI
Little is know about the use of tests to measure LV function after MI in practice and how this may have evolved over time. In a recent report from the Cooperative Cardiovascular Project, LVEF measurements were missing in 30% of the patients who survived hospitalization for a confirmed MI in the period 1994 to 1995 in acute-care hospitals in the United States. These data are consistent with data from a study of Medicare beneficiaries hospitalized in the period 1992 to 1993 and among whom LVEF was measured before discharge in 65% of the patients.
