Abstract

Background: Ranolazine is a novel antianginal medication approved for the treatment of chronic angina. There are only limited data concerning the efficacy of ranolazine in reducing healthcare resource utilization in patients with refractory angina pectoris. Objective: The primary objective of this analysis was to evaluate the efficacy and safety of ranolazine in refractory angina pectoris. In addition, the impact of ranolazine on healthcare resource utilization was assessed. Methods: Consecutive patients with refractory angina pectoris treated with ranolazine at two cardiology practices in the state of Nebraska were included in this analysis. The Canadian Cardiovascular Society (CCS) angina class and frequency and type of healthcare resource consumption were determined during the 12 months prior to and the 12 months after initiation of ranolazine. Results: A total of 150 pts (64 % men) with a mean age of 66 ± 12 years were included in this analysis. All patients had previously undergone coronary revascularization. Nitrates, β-adrenoceptor antagonists (β-blockers), and calcium antagonists (calcium channel blockers) were being used in 83, 97, and 75 % of patients, respectively. During ranolazine treatment, a significant improvement in CCS angina class was observed, with 23 patients improving by one class and no patient experiencing a deterioration in functional class (p = 0.025). A total of 53 side effects occurred in 28 (19 %) patients receiving ranolazine. Of those patients with side effects, four required dose reduction and seven required drug discontinuation. The frequency of clinic visits and emergency room visits was lower during ranolazine treatment, but the differences in frequency were not significant. The number of patients hospitalized and the number of hospitalizations were significantly lower during ranolazine therapy than in the pre-ranolazine study period (p = 0.002). Conclusion: Ranolazine improved the CCS angina class and reduced hospitalizations over a 12-month follow-up period in a group of patients with difficult-to-treat refractory angina pectoris.
