Several trials have shown that antihypertensive drug treatment decreases cardiovascular morbidity and mortality rates. They have also shown, however, that the risk is not decreased to the level of nonhypertensive patients. Trials are therefore underway to determine whether the benefits achieved by older drugs, such as diuretics and β blockers, can be enhanced by using newer classes of antihypertensive agents, such as calcium antagonists, angiotensin-converting enzyme (ACE) inhibitors, and angiotensin II receptor antagonists. Among these trials, the International Nifedipine GITS Study of Intervention as a Goal in Hypertension Treatment (INSIGHT) is of special interest because it is the first study to address, in a prospective fashion, the prognostic influence of antihypertensive treatment (nifedipine GITS vs a combined thiazide and potassium-sparing diuretic) in hypertensive patients with concomitant risk factors such as hypercholesterolemia, cigarette smoking, diabetes, and left ventricular hypertrophy. This article briefly describes the rationale and design of the INSIGHT trial and cites the substudies and the preliminary data available.
