In a large outcome study (MERLIN-TIMI 36) in 6,560 patients with UA/ NSTEMI ACS, there was no difference in the risk of all-cause mortality (relative risk ranolazine: placebo 0.99), sudden cardiac death (relative risk ranolazine: placebo 0.87), or the frequency of symptomatic documented arrhythmias (3.0% versus 3.1%) between Ranexa and placebo when added to standard medical therapy (including beta-blockers, calcium channel blockers, nitrates, anti-platelet agents, lipid-lowering medicinal products, and ACE inhibitors).
