According to published data, the ability to prevent various hypertension-related events differs between the various antihypertensive drug groups. Although absolute drug effects differ among studies, relative drug effects could be considered constant. We therefore explored the possibility of drawing statistically valid conclusions about the differences in clinical efficacy between various drug groups by doing an overview of published data. ⋯ There is statistically an indisputable difference between ACE inhibitors and calcium antagonists in respect of effects on coronary disease and heart failure when treating hypertensive individuals, ACE inhibitors being more efficacious. There are no differences in the effect on stroke. Moreover, beta-blockers or diuretics are also superior to calcium antagonists in preventing coronary events.
