Key result
ECG criteria show high specificity but low sensitivity for detecting increased LVMI in Afro-Caribbean hypertensives.
Why the study?
Cardiovascular disease is the leading cause of death in the Caribbean with hypertension causing left ventricular hypertrophy, but the accuracy of ECG to predict increased left ventricular mass index in Afro-Caribbean hypertensive patients is unclear.
Does the electrocardiogram accurately predict increased left ventricular mass index on echocardiogram in Afro-Caribbean hypertensive patients?
Cross-Sectional (n=111)
Does the electrocardiogram accurately predict increased left ventricular mass index on echocardiogram in Afro-Caribbean hypertensive patients?
Effect estimate: Sensitivity 3-31%, specificity 80-96%
The electrocardiogram is insensitive and less specific for detecting increased echocardiographic left ventricular mass index in Afro-Caribbean hypertensive patients.
No takes yet. Share an insight, caveat, or question.
ECG misses most increased LVMI cases in Afro-Caribbean hypertensives; leaves open whether echo should supplant ECG for risk stratification.
Martin et al. (2007) conducted a cross-sectional in Hypertension (n=111). Electrocardiogram vs. Echocardiogram was evaluated on Increased left ventricular mass index (Sensitivity 3-31%, specificity 80-96%). Electrocardiogram criteria had low sensitivity (3-31%) and high specificity (80-96%) for predicting increased left ventricular mass index in Afro-Caribbean hypertensive patients.
