Effect of hypertension on the morphology of coronary artery: analysis of 203 cases

To investigate the morphological features of the coronary artery visualized in angiography in hypertensive patients.A total of 203 patients (including 159 male and 44 female patients aged 29 to 75 years) with suspected coronary artery disease were studied during the period from November 1999 to November 2001. All the patients received clinical examination and selective coronary angiography, and were divided into hypertensive and normotensive groups for comparison.There were 5.7+/-1.2 vascular curves in the hypertensive group, but only 3.1+/-0.8 in normotensive group, showing significant differences between the 2 groups (P0.01). The bifurcation lesion was found in 34.5% patients in hypertensive group, but in only 23.1% in normotensive group (P0.01).Hypertensive patients have more cardiovascular curves and bifurcation lesions in comparison with normotensive patients.
