Organophosphate poisoning with coronary artery vasospasm confirmed by angiography

摘要

Organophosphate compounds are used worldwide as' agriculture pesticides and have become one of the most common causes of poisoning. High incidence of mortality has been reported in the past because of delay of diagnosis and improper treatment. Respiratory failure has been the main cause of mortality. Cardiovascular effects of organophosphate poisoning are sometimes serious but not fully appreciated by physicians. Mechanisms underlying the cardiovascular effects of organophosphate compounds are still unclear. Possible mechanisms include sympathetic and parasympathetic overactivity, hypoxaemia, acidosis and a direct toxic effect on the myocardium. Here, we report a rare case of coronary artery vasospasm cause by organophosphate poisoning.
