RESUMO
The work is carried out to clarify the mechanisms of cardiac activity disorders and assess the severity of cardiotoxicity in acute poisoning by combustion products in the age aspect. 71 patients with severe carbon monoxide poisoning were examined. The comparison group consisted of 22 patients with acute severe opiate poisoning. The methodological basis of the clinical study was daily monitoring of ECG. The studies were performed in 1 and 3-4 days. Residual cardiac dysfunction was estimated at 12-14 days. The comparison group selected 14 patients with acute myocardial infarction at this stage. Pathomorphological changes were studied on the cadaveric material of 24 experimental animals exposed to carbon monoxide at a dose of 16 g/m3 for 5 minutes on 31 days from toxic injury. It is established that acute poisoning by combustion products leads to the development of severe electrophysiological disorders classifying cardiotoxic effect as severe or extremely severe. Expression of signs of cardiotoxicity is higher in middle-aged and elderly patients. In the outcome of the poisoning, all the victims have formed a toxic cardiomyopathy.
