Left ventricular hypertrophy is more prevalent in patients with systemic hypertension with extracranial carotid arterial disease than in patients with systemic hypertension without extracranial carotid arterial disease.

The mechanism of the association between LV hypertrophy and ECAD is unknown and needs to be investigated. Whether LV hypertrophy in patients with systemic hypertension is a marker for ECAD or contributes to ECAD needs to be investigated. The association between LV hypertrophy and significant ECAD was independent of the level of blood pressure in our patients. Coronary atherosclerosis in our patients with signifciant ECAD may have contributed to the increased prevalence of LV hypertrophy. The association between LV hypertrophy and significant ECAD may contribute to the high incidence of stroke in patients with LV hypertrophy. This is currently under investigation by our group.
