| Popis: | A relationship between pulmonary dysfunction and cardiovascular mortality has been described. The mechanism responsible for the relationship remains largely unknown.The association between airflow obstruction and selected cardiovascular risk factors including gamma-glutamyl transferase (gamma-GT) and total homocysteine was analyzed cross-sectionally in 954 middle-aged men. Airflow obstruction was assessed with %FEV(1) (FEV(1)/FVC).Serum gamma-GT and white blood cell (WBC) count were higher in subjects with airflow obstruction (%FEV(1)70%) than in those without it (76.9+/-164.3 IU/L vs. 55.9+/-67.9 IU/L, P=0.030; 6290+/-1590/microL vs. 5590+/-1410/microL, P0.001). Airflow obstruction was not associated with body mass index, total cholesterol, triglycerides, fasting glucose, or systolic blood pressure, but there was a marginal association with total homocysteine. In a logistic regression analysis adjusted for smoking status and alcohol consumption, the odds ratios (95% confidence interval) of Delta100 IU/L increase in gamma-GT and Delta1000/microL increase in WBC count for the presence of airflow obstruction were 1.20 (0.97-1.48, P=0.090) and 1.21 (1.02-1.44, P=0.036), respectively.Airflow obstruction was associated with gamma-GT. The association was independent of alcohol consumption category, but was attenuated by the addition of cigarette smoking status. |
