Scientific title
Do xanthine oxidase inhibitors reduce left ventricular hypertrophy and endothelial dysfunction in normotensive patients with chronic stable angina?: a randomised double-blind placebo-controlled single-centre trial

Study hypothesis
To assess if allopurinol (a drug currently used to treat gout) reduces left ventricular hypertrophy and improve endothelial dysfunction in patients with normal blood pressure and stable angina.

Condition
Normotensive patients with left ventricular hypertrophy and chronic stable angina
Intervention
Patients will be given either allopurinol or placebo once a day orally. Patients will be given 100 mg for the first 2 weeks and then increased to 300 mg which is to be continued for further 4 weeks. Dosage will then be increased to 600 mg which is continue for a further 46 weeks (Total duration of interventions: 1 year).

Drug names
Allopurinol
Primary outcome measure
To assess left ventricular mass regression. This will be measured by cardiac MRI at baseline and then repeated after 1 year.
Secondary outcome measures
1. To assess endothelial function. This will be done by flow mediated dilatation and spygmocor. This will be performed at baseline, 6 months and then 1 year.
2. To assess if allopurinol reduces arrhythmogenicity. This will be done by looking at microvolt T wave alternans on electrocardiogram (ECG) at baseline and 1 year.
