Abstrakt: Verapamil is an effective and relatively-safe antihypertensive drug. Serious adverse effects are uncommon and mainly have been related to the depression of cardiac contractility and conduction, especially when the drug is combined with beta-blocking agents. We report a case in which myocardial infarction coincided with the introduction of captopril and the withdrawal of verapamil in a previously asymptomatic woman with severe hypertension. Possible mechanisms that involve a verapamil-related increase in platelet and/or vascular alpha 2-adrenoreceptor affinity for catecholamines are discussed.
