Why the study?

Does echocardiographic LV mass or ECG criteria accurately diagnose left ventricular hypertrophy compared to anatomic findings?

Structured PICO

Does echocardiographic LV mass or ECG criteria accurately diagnose left ventricular hypertrophy compared to anatomic findings?

Population

176 subjects, including 34 in a necropsy series, 100 in an unselected clinical series, 28 with severe aortic stenosis, and 14 with severe aortic regurgitation.

Intervention

Echocardiographic LV mass and ECG criteria (Romhilt-Estes point score and Sokolow-Lyon voltage criteria)

Comparator

Postmortem LV weight (anatomic findings)

Outcome

Diagnostic accuracy (sensitivity, specificity, correlation) for left ventricular hypertrophysurrogate

M-mode echocardiographic LV mass is superior to ECG criteria for the clinical diagnosis of left ventricular hypertrophy due to the low sensitivity of ECG.

Discussion

No takes yet. Share an insight, caveat, or question.

Implication

May support echocardiography over ECG for LVH diagnosis; leaves open prospective outcome validation before practice change.
