Why the study?
Does echocardiography detect cardiac abnormalities more frequently than ECG or chest x-ray in asymptomatic subjects with mild-to-moderate systemic hypertension?
Population
234 asymptomatic subjects with mild-to-moderate systemic hypertension
Comparison
Echocardiography vs 12-lead ECG and chest x-ray
Design
Cross-sectional

Echocardiography may detect subclinical LVH missed by ECG or chest x-ray in asymptomatic hypertension; leaves open whether routine screening improves outcomes.
Does echocardiography detect cardiac abnormalities more frequently than ECG or chest x-ray in asymptomatic subjects with mild-to-moderate systemic hypertension?
Echocardiography detects a high prevalence of cardiac abnormalities in asymptomatic hypertensive patients before they are apparent on standard ECG or chest x-ray.
