Ranolazine After Incomplete Percutaneous Coronary Revascularization in Patients With Versus Without Diabetes Mellitus: RIVER-PCI Trial.

Journal Article

BACKGROUND: Chronic angina is more common in patients with diabetes mellitus (DM) with poor glucose control. Ranolazine both treats chronic angina and improves glucose control. OBJECTIVES: This study sought to examine ranolazine's antianginal effect in relation to glucose control. METHODS: The authors performed a secondary analysis of the RIVER-PCI (Ranolazine in Patients with Incomplete Revascularization after Percutaneous Coronary Intervention) trial, a clinical trial in which 2,604 patients with chronic angina and incomplete revascularization following percutaneous coronary intervention were randomized to ranolazine versus placebo. Mixed-effects models were used to compare the effects of ranolazine versus placebo on glycosylated hemoglobin (HbA1c) at 6- and 12-month follow-up. Interaction between baseline HbA1c and ranolazine's effect on Seattle Angina Questionnaire angina frequency at 6 and 12 months was tested. RESULTS: Overall, 961 patients (36.9%) had DM at baseline. Compared with placebo, ranolazine significantly decreased HbA1c by 0.42 ± 0.08% (adjusted mean difference ± SE) and 0.44 ± 0.08% from baseline to 6 and 12 months, respectively, in DM patients, and by 0.19 ± 0.02% and 0.20 ± 0.02% at 6 and 12 months, respectively, in non-DM patients. Compared with placebo, ranolazine significantly reduced Seattle Angina Questionnaire angina frequency at 6 months among DM patients but not at 12 months. The reductions in angina frequency were numerically greater among patients with baseline HbA1c ≥7.5% than those with HbA1c <7.5% (interaction p = 0.07). CONCLUSIONS: In patients with DM and chronic angina with incomplete revascularization after percutaneous coronary intervention, ranolazine's effect on glucose control and angina at 6 months was proportionate to baseline HbA1c, but the effect on angina dissipated by 12 months.
