Abstract

OBJECTIVE: To study the clinical significance of changes of serum myocardial enzymes in patients with acute carbon monoxide poisoning. METHODS: To determine the dynamic changes of the activity of myocardial enzymes and ECG in 62 patients with acute CO poisoning. RESULTS: In patients with acute CO poisoning 5 kinds of myocardial enzymes begin to increase within 24 hours, the activities of aspartate aminotransferase (AST), creatine phosphokinase (CPK), lactic dehydrogenase (LDH), alpha-hydroxybutyrate dehydrogenase (alpha-HBDH), CPK isoenzyme (CK-MB) were (20.2 +/- 12.3), (151.6 +/- 91.8), (146.8 +/- 50.4), (154.8 +/- 47.7), (13.8 +/- 8.1) U/L respectively, while those in control group were (12.1 +/- 6.7), (90.6 +/- 17.3), (118.7 +/- 13.5), (89.9 +/- 27.9), (5.9 +/- 3.3) U/L respectively. There was significant difference between two groups (P < 0.01); 3 d later, the activities of 5 enzymes were still increased [(21.3 +/- 12.3), (105.8 +/- 51.4), (144.8 +/- 51.4), (159.8 +/- 35.4), (16.2 +/- 9.1) U/L respectively]. 7 and 12 d later, the activities of alpha-HBDH and CK-MB were still higher than those of control (P < 0.01). LDH(1) and LDH(2) increased to peak value in 24 h after poisoning (35.3 +/- 5.8), (43.8 +/- 5.7) U/L vs (24.8 +/- 3.9), (36.9 +/- 4.3) U/L, P < 0.01. The abnormal rate of serum LDH(1) was 78.7%, LDH(2) 58.3%, LDH 45.2%, CK-MB 37.1%, alpha-HBDH 33.6% and the abnormal rate of ECG was less than 10%. CONCLUSION: Acute carbon monoxide poisoning may cause myocardial injury. Determination of serum myocardial enzymes may contribute to showing myocardial injury, early diagnosis and treatment, results of treatment and prognosis.
