Why the study?
Do current ECG criteria accurately diagnose left ventricular hypertrophy compared to transthoracic echocardiography in hospitalized patients?
Population
2134 patients with ECG and echocardiography during the same hospitalization
Comparison
Known ECG criteria for LVH vs transthoracic echocardiography
Design
Retrospective observational study
Key result
Current ECG criteria for left ventricular hypertrophy have low sensitivity, though Cornell voltage and Cornell product demonstrated the most accurate diagnostic performance (AUC 0.678 for Cornell voltage).

ECG criteria should not replace echocardiography for LVH diagnosis in hospitalized patients; leaves open optimization of Cornell thresholds in prospective studies.

Do current ECG criteria accurately diagnose left ventricular hypertrophy compared to transthoracic echocardiography in hospitalized patients?
Current ECG criteria for LVH have low sensitivity despite acceptable specificity, with Cornell voltage and product offering the most accurate diagnostic performance among them.
Ricciardi et al. (2019) conducted an observational in Left ventricular hypertrophy (n=2,134). ECG criteria for LVH vs. Transthoracic echocardiography was evaluated on Diagnostic performance (AUC, sensitivity, specificity) of ECG criteria for LVH. Current ECG criteria for left ventricular hypertrophy have low sensitivity, though Cornell voltage and Cornell product demonstrated the most accurate diagnostic performance (AUC 0.678 for Cornell voltage).
