Outcomes
Primary Outcome Measures
Change in time to exercise induced ST depression
A continuous ECG tracing will be recorded. Time to >1mm change in ST measurements will be noted. Exercise Tolerance testing (ETT) 1 hour before study drug administration is baseline measurement. Comparisons will be made 4 hours, 1 day and 5 days after baseline ETT.
Secondary Outcome Measures
change in total exercise time on Exercise Tolerance Testing (ETT)
A continuous ECG tracing will be recorded. Time to total exercise time, ie when patient can walk no further will be noted. Exercise Tolerance Testing (ETT) 1 hour before study drug administration is baseline measurement. Comparisons will be made 4 hours, 1 day and 5 days after baseline ETT.
Change in time to subjects reported symptoms of chest pain during exercise testing.
A continuous ECG tracing will be recorded. Time to reported chest pain will be noted. Exercise Tolerance testing (ETT) 1 hour before study drug administration is baseline measurement. Comparisons will be made 4 hours, 1 day and 5 days after baseline ETT.
changes in blood markers, specifically Brain Naturetic Peptide (BNP), high sensitivity Troponin T and high sensitivity C Reactive Protein (hsCRP), during exercise testing
Baseline is pre 1st study drug dose exercise tolerance test (ETT). Comparisons will be made before and after 4 hour post drug ETT
angina pain and Glyceryl TriNitrate (GTN) usage
subjects will use angina log to record symptoms of angina and GTN usage between hospital visits

5. Study Description
Brief Summary
Allopurinol is a drug commonly used to treat gout. However recent studies have shown it has the potential to help improve oxygen supply to heart muscle. In this study the Investigators aim to find out if allopurinol slows down the onset of angina symptoms, as seen by a doctor on a tracing of the heart (ECG- electrocardiogram), for patients who have been diagnosed with heart disease, when exercising on a treadmill. The Investigators are also are trying to figure out the best dose of allopurinol to use and to see how quickly it begins working. To do this the investigators will recruit patients with angina, exercise them on a treadmill after giving different doses of allopurinol and see if there is an improvement in their time to bring on angina symptoms and signs. Patients recruited to this trial will receive three different treatment regimes over a six week period. Each treatment regime will last for one week with a one week rest period between each regime. This will involve up to eleven visits to Ninewells Medical School, Dundee for testing.
