Objective To investigate the effects of press of Oxygen p (O 2) on serum cardiac tropnin I(CTnI) in patients suffering from chronic obstruct pulmonary disease(COPD).Methods Serum CTnI, the myocardial enxymes and p (O 2) were measured. In three groups, observe the changes and relations between CTnI and p (O 2).Results The values of CTnI were (0.15±0.08)μg/L in patients with mild hypoxemia COPD, (0.87±0.92)μg/L in patients with moderate hypoxemia COPD, (2.24±0.97)μg/L in the patients with severe hypoxemia COPD (2.24±0.97)μg/L. There were significant differences in three groups ( P 0.05 ). p (O 2) in patients of three groups had a negative relation with CTnI( r =-0.968?1, P 0.05). CTnI in average were(3.62±1.08)μg/L. In 8 patients of death, the CTnI level were significantly higher than those of the survival patients( P 0.05) .Conclusion Hypoxemia may significantly lead to increase of CTnI of patients with COPD, but it had a significant negative relation with p (O 2) level. When level of CTnI increases, it may attention to severed symptom in the patients.
