ABSTRACT
<p><b>OBJECTIVE</b>To observe the relationship between the parameters of artery elasticity and coronary artery stenosis in normotensive and hypertensive patients with coronary artery disease (CAD).</p><p><b>METHODS</b>Systemic vascular compliance (SVC), systemic vascular resistance (SVR), brachial artery compliance (BAC) and brachial artery resistance (BAR) were measured by Dynapulse 200M (Pulse Metric, Inc., USA) in 88 hypertensive and 41 normotensive patients with chest pain before coronary artery angiography.</p><p><b>RESULTS</b>(1) The prevalence rate of severe coronary disease (> or = 2 coronary branches) was higher in hypertensives than in normotensives (64.7% vs. 27.1%, P < 0.05); (2) the peripheral artery buffering function was significantly lower in hypertensives than in normotensives [SVC (0.85 +/- 0.10) ml/mm Hg (1 mm Hg = 0.133 kPa) vs. (1.17 +/- 0.11) ml/mm Hg; BAC (0.047 +/- 0.011) ml/mm Hg vs. (0.063 +/- 0.010) ml/mm Hg, all P < 0.05]; (3) Lower arterial elasticity was associated with severe coronary artery stenosis.</p><p><b>CONCLUSION</b>The non-invasive obtained artery elasticity is associated with the degree of coronary artery stenosis in hypertensive patients with CAD.</p>
