Distensibility of the ascending aorta: comparison of invasive and non-invasive techniques in healthy men and in men with coronary artery disease

Distensibility of the ascending aorta, measured non-invasively, was compared with values obtained by invasive techniques in 46 males (30 patients with coronary artery disease and 16 age-matched normal subjects). Aortic diameters were measured at a level 3 cm above the aortic valve using both echocar...

Description
Summary:Distensibility of the ascending aorta, measured non-invasively, was compared with values obtained by invasive techniques in 46 males (30 patients with coronary artery disease and 16 age-matched normal subjects). Aortic diameters were measured at a level 3 cm above the aortic valve using both echocardiographic and angiographic techniques. Aortic distensibility was calculated from the aortic diameters and aortic pressure or brachial artery pressure using the formula: 2 × (change in aortic diameter) /(diastolic aortic diameter) × (change in aortic pressure). Distensibility of the ascending aorta determined non-invasively was closely related to that obtained by direct measurements (r = 0.949, P
