    Abstract:
    The aim of our study was to assess the effects of diltiazem on diastolic function, left ventricular mass and intradialytic hypotension, in uremic patients on maintenance hemodialysis. Forty-eight uremic patients on maintenance hemodialysis (mean age 46 +/- 5 years) with diastolic heart failure and normal systolic function (ejection fraction > 40%), although hemodialysis had been correctly performed, were included in the study. All patients had left ventricular hypertrophy. Diltiazem was given at the dosage of 60 mg, twice a day, for 3 months. At the end of this period, significant improvement of Doppler echocardiographic filling pattern and clinical symptomatology were observed, but left ventricular mass index was unchanged. Episodes of intradialytic hypotension were significantly reduced. We conclude that diltiazem improves symptoms and left ventricular diastolic filling in uremic patients with diastolic heart failure, without modifying left ventricular mass index; impaired diastolic function has an important role in recurrent dialysis hypotension.
