Observational StudyEvaluation of cardiac function using transthoracic echocardiography in patients with myocardial injury secondary to methomyl poisoning.
Generally, the mortality rate for cases of carbamate poisoning is low, but fatalities secondary to methomyl poisoning have been reported including a case report of cardiac toxicity following short-term exposure to methomyl. There have been no reports, however, regarding patterns of cardiac toxicity after exposure to methomyl. Therefore, we investigated the prevalence and patterns of myocardial injury using a biochemical marker, troponin I (TnI), and evaluated cardiac function using transthoracic echocardiography (TTE). ⋯ One patient (8.3%) was died to follow-up, and 11 patients survived without any further complications. Methomyl exposure can cause direct myocardial injury and reversible cardiac dysfunction. Monitoring of TnI levels and TTE for evaluation of cardiac function may be useful in the workup of patients suffering from methomyl poisoning.
