Association of Carotid Atherosclerosis With Electrocardiographic Myocardial Ischemia and Left Ventricular Hypertrophy
Why the study?
Are electrocardiographic myocardial ischemia and left ventricular hypertrophy associated with the presence of carotid atherosclerosis in asymptomatic subjects?
Population
349 asymptomatic subjects who underwent echocardiography and carotid ultrasonography
Comparison
Electrocardiographic evidence of myocardial… vs Subjects without electrocardiographic evidence…

Implication
ECG ischemia or LVH may flag higher carotid atherosclerosis risk in asymptomatic patients; leaves open whether targeted screening improves outcomes.
Structured PICO
Are electrocardiographic myocardial ischemia and left ventricular hypertrophy associated with the presence of carotid atherosclerosis in asymptomatic subjects?
P
Population
349 asymptomatic subjects who underwent echocardiography and carotid ultrasonography
I
Intervention
Electrocardiographic evidence of myocardial ischemia (localized T-wave inversions) or left ventricular hypertrophy (product of Cornell voltage and QRS duration)
C
Comparator
Subjects without electrocardiographic evidence of myocardial ischemia or left ventricular hypertrophy
O
Outcome
Presence of carotid atherosclerosissurrogate
Electrocardiographic evidence of myocardial ischemia and left ventricular hypertrophy are strong independent predictors of carotid atherosclerosis in asymptomatic individuals.
