Diagnostic accuracy of different electrocardiographic and radiographic criteria for left atrial enlargement as assessed by cardiac magnetic resonance

Presence of left atrial enlargement is a predictor of significant cardiovascular morbidity and mortality in various populations, particularly hypertensive patients. Although the electrocardiogram (ECG) and chest X-ray (CXR) are the standard tests in clinical practice, the diagnostic performance of these tests as compared to the promising gold standard for the diagnosis of left atrial enlargement (LAE), cardiac magnetic resonance (CMR) is not well evaluated. This study was sought to assess the accuracy of the ECG and CXR criteria to diagnose LAE determined by volumetric CMR.
