Data in parentheses are 95% confidence intervals. Diastolic dysfunction included impaired relaxation, pseudonormal and restrictive filling patterns. Mitral regurgitation included moderate and severe mitral regurgitation. MI, myocardial infarction; TIMI, thrombolysis in myocardial infarction; hsTnT, high sensitivity troponin T; LVEF, left ventricular ejection fraction; MVO, microvascular obstruction; MSI, myocardial salvage index; LA, left atrial; LAEF, left atrial ejection fraction; LAVImax, maximum indexed left atrial volume; LAVImin, minimum indexed left atrial volume.
