Atrial emptying index may better indicate exercise capacity than LVEF in young post-MI men; hypothesis-generating, requiring prospective confirmation before any practice change.
Do measurements of left ventricular systolic and diastolic function predict exercise capacity in young male survivors of myocardial infarction?
Left ventricular diastolic function, specifically the atrial emptying index, is a better predictor of exercise capacity than systolic function in young men following a myocardial infarction.
Eriksson et al. (1998) studied this question.
