EXTREME BRADYCARDIA IN COCAINE-ISOLATED USE

Introduction and Objetive. Describe the variability of cardiovascular effects of cocaine use in order to emphasize the gravity in consumption, even isolated, of this substance Method: 38 year old patient with no history of interest referring cocaine use suffers syncope during clinic history Results: During syncope asystole is evidence of at least four seconds wich required cardiopulmonary resuscitation on two occasions and is referred to a coronary unit for suspected coronary syndrome by vasospasm in cocaine use Conclusions: Cocaine supposes a major health problem. Cocaine use is associated with adverse events in nearly every organ system. Cardiovascular complications include hemorrhagic and ischemic stroke, aortic dissection, cardiomyopathy, accelerated coronary artery disease, myocardial infarction, and sudden cardiac death. The adverse cardiovascular changes and sympathetic stimulation associated with cocaine and amphetamine ingestion predispose to myocardial electrical instability, precipitating a wide and unpredictable range of supraventricular and ventricular arrhythmias. Syncope may be the presenting symptom in these conditions. However, cocaine-induced bradyarrhythmias have been scarcely mentioned. Cardiovascular effects are not dependent or dose,the route of administration or frequency of use.
