Abstract
Background
We investigated the potential of oral nicorandil to improve myocardial fatty acid metabolism assessed by single-photon emission computed tomography (SPECT) using 123I-β-methyliodophenyl pentadecanoic acid (BMIPP) in hemodialysis patients without obstructive coronary artery disease (CAD).
Methods
This study was based on a cohort study of 155 hemodialysis patients with angiographic absence of obstructive CAD, with analysis performed in 100 propensity-matched patients (54 men and 46 women, 64 ± 10 years); 50 with oral administration of nicorandil (15 mg/d, nicorandil group) and 50 without (control). BMIPP SPECT was performed every year after angiography. Uptake on SPECT was graded in 17 segments on a five-point scale (0 normal, 4 absent) and assessed as BMIPP summed scores (SS).
Results
Over a mean follow-up period of 5.3 ± 1.9 years, we observed 25 cardiac deaths among 100 propensity-matched patients. Myocardial uptake of BMIPP in SPECT improved in the nicorandil group compared with the control group from 2 years of administration. In Kaplan–Meier survival analyses, free survival rate from cardiac death was higher in patients with a BMIPP SS improvement rate of ≥20 % compared to those with ≥0 % <20 % or with <0 % BMIPP SS improvement rate. At multiple logistic analysis, a ≥20 % BMIPP SS improvement rate was positively associated with serum albumin concentration and oral nicorandil.
Conclusions
Long-term oral nicorandil may inhibit cardiac death by improving myocardial fatty acid metabolism in hemodialysis patients without obstructive CAD.
