| Scientific title | Effect of allopurinol on arterial stiffness indices in patients with chronic heart failure: a prospective randomised double-blind placebo-controlled study |
| Study objectives | Allopurinol add-on therapy (300 mg daily dose for 3 months) in clinically-stable patients with chronic heart failure will result in reduction of arterial stiffness parameters, augmentation index (AIx) and aortic pulse wave velocity (PWV) (carotid-femoral). |
| Ethics approval(s) | The University of Dammam (now Imam Abdulrahman bin Faisal University) Ethics Committee, 26/05/2010 |
| Health condition(s) or problem(s) studied | Chronic heart failure |
| Intervention | Every patient will have a total of 4 visits. Preliminary visit: For explaining the nature of the trial, get the consent forms signed and for demonstration of SphygmoCardiography technique and to get the patient acclimatised to it via taking some arterial stiffness readings that will not be included in the study statistics. Blood samples will be taken for baseline screening; haematological and biochemical screening. Baseline echocardiogram and ECG will also be done. Visit 0: For arterial stiffness parameters measurements and baseline stress test, after which the patient will be randomised by a pharmacist to any of the treatment arms. Safety visit: For checking how the patient is doing with the study medication (1 month after). Blood samples will be taken for complete blood count, renal and liver function tests. Visit 1 (3 months post-randomisation): For arterial stiffness parameters measurements and a repeat stress test. Medications: Allopurinol: Apo-Allopurinol 300 mg tablet once daily (APOTEX Pharmaceutical, Canada). Duration: 90 days. Placebo: manufactured locally at Al Jazeera Pharmaceutical, Riyadh, Saudi Arabia, 1 tablet once daily. Duration: 90 days. |
