Calcium channel blockers for people with chronic kidney disease requiring dialysis.
Summary
This study is a pilot study designed to compare the safety and cardiovascular effects of 26 weeks of combination hydralazine/isorsorbide dinitrate therapy with placebo therapy in patients receiving chronic hemodialysis.
The investigators hypothesize that treatment of chronic hemodialysis (ESRD) patients with a combination of hydralazine/isosorbide dinitrate compared with placebo is safe and that it will improve heart function as well blood flow/blood vessel supply.
