Abstract
A major controversy about the safety of calcium channel blockers (CCBs) has arisen since the publication of a case-control study showing that hypertensives who suffered an acute myocardial infarction (MI) were more likely than hypertensives who had not had an MI to be taking one of these (short-acting) agents than other antihypertensive agents. This study was accompanied by a republication of older studies showing that large doses of short-acting nifedipine given to post-MI patients increased their mortality rate. The danger of massive doses of short-acting nifedipine in a post-MI patient is real but irrelevant to current practice. On the other hand, the putative dangers of short-acting CCBs in the treatment of hypertension do not apply to the current use of long-acting CCBs. Therefore the scare over their use is both irrational and unfortunate. (Hypertens Res 1996; 19: 57-64)
