IONA Impact Of Nicorandil in Angina A Presentation given by Henry J Dargie Western Infirmary and University of Glasgow at the AHA Conference 14th Nov 2001
IONA • Background : • Angina is common - affects over 10% of men and women over 60 • Angina is disabling - quality of life can be poor • Angina affects outcome variably - 3% to 20% annual rate of cardiac events
Anti anginal : nitrates beta blockers Ca++ channel blockers nicorandil Disease modifying : anti-platelet statin ACE inhibitors IONA- current medical treatment of angina
IONA • Objective : To investigate the impact of nicorandil on outcome in patients with angina of effort - when added to existing treatments
IONA • Primary Hypothesis : Treatment with nicorandil will reduce the incidence of the primary endpoint by 25% • Primary End Point : Coronary Heart Disease Death + Non fatal Myocardial Infarction + Unplanned Hospitalisation for Cardiac Chest Pain
IONA • Secondary End Point : • Coronary Heart Disease Death • + • Non Fatal Myocardial Infarction
IONA • Exploratory Analyses : • All cause mortality • All cardiovascular events
IONA • Design and Methodology : • Double blind, randomised controlled trial of nicorandil versus placebo • 10 mg bd increasing to 20 mg bd after 2 weeks • Higher risk patients on existing medication • not being actively considered for revascularisation • Conducted exclusively in the UK • recruitment from hospital and primary care • Analysis was by intention to treat
IONA • Inclusion criteria • Men or women • Stable angina with high risk features • Need for regular oral anti anginal medication (long acting nitrate, beta blocker or calcium channel blocker)
IONA • Recruitment and follow up • 5126 patients recruited • 2561 (P), 2565 (N) • Average follow up of 1.6 years • (1- 3 years)

IONA • Summary • In patients with chronic stable angina: • Nicorandil significantly reduced the incidence of major coronary events and all cardiovascular events • IONA is the first large scale clinical trial to report on the effects of a specific anti - anginal medication on clinical outcome
