Left Atrial Enlargement and Phasic Function in Patients Following Non-ST Elevation Myocardial Infarction

Patients with NSTEMIs had progressive LA enlargement with reductions in conduit and active emptying volumes, reflecting persistent left ventricular diastolic dysfunction consequent to coronary artery disease and associated diabetes. The measurement of LA volumes after NSTEMI may be useful to monitor chronic diastolic dysfunction resulting from ischemic burden.
