Antihypertensive & Lipid Lowering Treatment to Prevent Heart Attack Trial. An ongoing trial evaluating whether antihypertensive therapy decreases morbidity and mortality in CAD, and whether lipid-lowering in moderately hypercholestaeremic patients decreases cardiovascular morbidity and mortality
Conclusion No major differences for antihypertensives and lipid-lowering agents in fatal CHD or nonfatal MIs

ALLHAT

Cardiology An ongoing randomized, open label, multicenter trial evaluating whether antihypertensive therapy reduces M&M in CAD, and to determine whether lipid-lowering pravastatin therapy in moderately hypercholesteremic Pts reduces heart-related M&M.
