Text: Smoking was associated with significant changes in the aortic pressure-diameter relation that denote deterioration of the elastic properties and were maintained during the whole study period : the slope of the pressure-diameter loop became steeper (baseline, 35. 43 + / - 1. 38 ; minute 1, 45. 26 + / - 1. 65 ; peak at minute 10, 46. 36 + / - 1. 69 mm Hg/mm ; P <. 001) and aortic distensibility decreased (baseline, 2. 08 + / - 0. 12 ; minute 1, 1. 60 + / - 0. 08 ; nadir at minute 5, 1. 54 + / - 0. 07 x 10 (-6) cm2. dyne-1 ; P <. 001).
