Although active smoking is known to enhance platelet thromboxane production, no data on passive smoking are available yet. In an 18 m room, the influence of single and repeated exposure to passive smoke for 60 minutes was assessed in nonsmokers and smokers. Smokers and nonsmokers were matched for sex and age. All the evaluated parameters (plasma TXB, serum TXB, malondialdehyde, 11-dehydro-TXB, conversion of exogenous arachidonic acid to hydroxy-5,8,10-heptadecatrienoic acid, and TXB) were higher in smokers than nonsmokers at baseline conditions, immediately and 6 hours after passive exposure to cigarette smoke. Repeated exposure of nonsmokers rendered their platelets more activated, so they became closer to the behavior of smokers. Contributing to the development of hemostatic imbalance, these results indicate that passive smoking may enhance thromboxane A release from the platelets. [ABSTRACT FROM AUTHOR] |
