Thrombotic complications of pulmonary circulation occur in patients with chronic obstructive pulmonary disease (COPD). In the present study, we sought to evaluate in vivo platelet activation through the measurement of 11/dehydro-thromboxane (Tx) B2 TxA2 major metabolite in the urine, in 29 patients with COPD, compared with 29 sex- and age-matched healthy subjects. The urinary excretion of 11-dehydro-TxB2 was significantly higher in patients with COPD than in control subjects: median (range), 753 (277-4,409) and 275 (129-612) pg/mg creatinine, respectively; p
