In healthy habitual smokers acetylsalicylic acid abolishes the effects of tobacco smoke on the platelet aggregate ratio.

Abstract

After abstinence for at least 8 hours, 20 healthy habitual smokers smoked two unfiltered cigarettes during each of two 20-minute periods separated by 48 hours. They had taken one 0.32-g tablet of acetylsalicylic acid (ASA) the night before the second period. The mean platelet aggregate ratios in venous blood taken immediately before and after each period of smoking were 0.79 and 0.70 respectively when ASA had not been taken beforehand and 0.89 and 0.91 when it had. The mean after smoking was significantly higher when ASA had been taken beforehand. In conjunction with the previous finding that in nonsmokers ASA prevented a lowering of the platelet aggregate ratio by experimental smoking without affecting the ratio before smoking, the data from the present study suggest that ASA abolishes both acute and longer-lasting effects of tobacco smoke on the platelet aggregate ratio in healthy habitual smokers.
