Prediction of heart failure and adverse cardiovascular events in outpatients with coronary artery disease using mitral E/A ratio in conjunction with e-wave deceleration time: The heart and soul study
Coronary Artery Disease
Ventricular Function, Left
In ambulatory patients with stable CAD, restrictive filling (E/A ratio ≥ 1.5) is a powerful predictor of HF. Among those with normal mitral E/A ratios (0.75-1.5), only DT/pE predicts HF, while neither DT nor DT/pE predicts other MACEs. This suggests that mitral E/A ratio has significant prognostic value in patients with CAD, and in those with normal mitral E/A ratios, the normalization of DT to pE augments its prognostic power.
