Abstract

BACKGROUND: The anatomy of left ventricular hypertrophy (LVH) in dialysis patients was studied with magnetic resonance imaging (MRI). Potential benefits of spironolactone were examined in a subset of patients.

METHODS: This was a prospective case series of 30 hemodialysis patients in whom cardiac MRI was performed. Repeat MRI was done in a subset of 13 patients after 9 months of daily oral spironolactone 25 mg.

RESULTS: Subjects exhibited a characteristic cardiac morphology, distinct from both concentric LVH (cLVH) and eccentric LVH (eLVH). Compared with normal controls, LV mass index was increased, end-diastolic volume index was increased, and ejection fraction was reduced, but sphericity indices did not differ. No significant changes were seen after spironolactone.

CONCLUSIONS: LVH in dialysis patients has a unique MRI appearance which is distinct from either cLVH or eLVH, with profound LV thickening and moderate dilation of the ventricular cavity. A 9-month course of spironolactone therapy did not affect morphology.
