In all, 22,599 patients with coexisting hypertension and coronary artery di
sease (CAD) from around the world are enrolled in the INternational VErapam
il SR/trandolapril STudy (INVEST). As a result, much will be learned regard
ing the use of treatment strategies using verapamil SR and atenolol with an
d without trandolapril and/or hydrochlororthiazide in patients with hyperte
nsion and CAD, all of whom are at high risk for adverse cardiovascular outc
omes. This trial will provide meaningful data on optimal treatment strategi
es for hypertension, especially among patients who are elderly, have diabet
es, have left ventricular hypertrophy, or who are dyslipidemic. This trial
will be the first to use Joint National Committee on Detection, Evaluation,
and Treatment of High Blood Pressure (JNCVI) guidelines as blood pressure
goals to determine the relative benefits of a calcium antagonist versus a b
eta-blocker strategy in reducing morbidity and mortality. In addition, wome
n and Hispanic patients participating in INVEST will provide the largest co
ntrolled experience in the management of hypertensive patients with CAD, fa
cilitating the development of future guidelines.
