Study Protocol for Rosiglitazone Versus Gliclazide in Diabetics With Angina

2014-08-27 03:48:44 | BioPortfolio


The principle objective of the trial is to compare rosiglitazone to gliclazide in patients with type 2 diabetes mellitus and chronic stable angina to see how the subjects' angina status changes.

Angina status will be measured via exercise tolerance testing, 24-hour ECG testing and angina quality of life questionnaire.


Ischaemic heart disease is one of the main complications of type 2 diabetes mellitus, both in terms of morbidity and mortality. Reducing plasma glucose with hypoglycaemic agents has not been shown to improve cardiovascular mortality or morbidity. Chronic stable angina is a common problem in patients with type 2 diabetes mellitus.

We postulate that in subjects with uncontrolled type 2 diabetes mellitus (Hba1c >7.5%), on metformin therapy, and chronic stable angina that the addition of the insulin sensitiser, rosiglitazone to control their diabetes will improve their angina when compared to the addition of the hypoglycaemic agent gliclazide. This hypothesis is based on the fact that insulin resistance is an upstream mechanism common to both conditions.

We will randomise such patients to 3 months therapy of rosiglitazone or gliclazide for 3 months, comparing angina status before and after by way of full Bruce protocol exercise testing, 24 hour ST segment analysis and angina questionnaire.

Medical and Biotech [MESH] Definitions

A drug used in the treatment of angina pectoris, heart failure, conduction defects, and myocardial infarction. It is a partial agonist at beta adrenergic receptors and acts as a coronary vasodilator and cardiotonic agent.

ANGINA PECTORIS or angina-like chest pain with a normal coronary arteriogram and positive EXERCISE TEST. The cause of the syndrome is unknown. While its recognition is of clinical importance, its prognosis is excellent. (Braunwald, Heart Disease, 4th ed, p1346; Jablonski Dictionary of Syndromes & Eponymic Diseases, 2d ed). It is different from METABOLIC SYNDROME X, a syndrome characterized by INSULIN RESISTANCE and HYPERINSULINEMIA, that has increased risk for cardiovascular disease.

A drug formerly used in the treatment of angina pectoris but superseded by less hazardous drugs. Prenylamine depletes myocardial catecholamine stores and has some calcium channel blocking activity. (From Martindale, The Extra Pharmacopoeia, 30th ed, p1406)

A cardioselective beta-1-adrenergic blocker. It is effective in the management of hypertension and angina pectoris.

A beta-adrenergic antagonist used in the treatment of hypertension, angina pectoris, arrhythmias, and anxiety.
