Rationale and design of the International Verapamil SR/Trandolapril Study (INVEST): an Internet-based randomized trial in coronary artery disease patients with hypertension.
OBJECTIVES The primary objective of the International Verapamil SR/Tr and olapril Study ( INVEST ) is to compare the risk for adverse outcomes ( all-cause mortality , nonfatal myocardial infa rct ion [ MI ] or nonfatal stroke ) in hypertensive patients with coronary artery disease ( CAD ) treated with either a calcium antagonist-based or a noncalcium antagonist-based strategy .  BACKGROUND Treatment recommendations for hypertension include initial therapy with a diuretic or beta-adrenergic blocking agent , for which reductions in morbidity and mortality are documented from r and omized trials but are less than expected from epidemiologic data . For this reason , recent attention has focused on calcium antagonists or angiotensin-converting enzyme inhibitors . While these agents reduce blood pressure , outcome data from large r and omized trials are lacking , but some case-control data , dominated by short-acting dihydropyridines , suggest an increased risk of cardiovascular events . These studies had method ologic limitations and did not differentiate among calcium antagonist types and formulations . Several studies differentiating among calcium antagonist types and an overview of published r and omized trials show no increased risk with verapamil and suggestion for benefit in CAD patients . METHODS A total of 27,000 CAD patients with hypertension will be r and omized at 1,500 primary care sites to receive either a calcium antagonist-based ( verapamil ) or beta-blocker/diuretic-based ( atenolol/hydrochlorothiazide ) antihypertensive care strategy . The study uses a novel , electronic " paper-less " system for direct on-screen data entry , r and omization and drug distribution from a mail pharmacy linked to the coordination center via the Internet . RESULTS Contract negotiations with the United States and international sites are ongoing . Patients being enrolled are predominantly elderly ( 72 % aged 60 years or older ) men ( 54 % ) , with either an abnormal coronary angiogram or prior MI ( 71 % ) . In addition to hypertension , CAD and elderly age , most patients ( 89 % ) have one or more associated conditions ( diabetes , dyslipidemia , smoking , cerebral or peripheral vascular disease , etc . ) contributing to increased risk for adverse outcome . While 26 % have diabetes , most of these are noninsulin dependent . Using the protocol strategies , target blood pressures ( according to JNC VI ) have been reached in 58 % at the fourth visit , and as expected most ( 89 % ) are requiring multiple antihypertensive drugs . CONCLUSION The design and baseline characteristics of the initial patients recruited for a prospect i ve , r and omized , international , multicenter study comparing two therapeutic strategies to control hypertension in CAD patients are described
