Abstract

Objective To evaluate the relationship between pulse pressure(PP)and the severity of coronary artery stenosis.Methods 405 patients were enrolled.Of them,271 were men and 134 women,whose ages were 33-85(63.02±11.18)years.All patients underwent coronary angiography.The severity of coronary artery stenosis was evaluated by the number of diseased arteries and Gensini score.Aortic blood pressure and radial artery blood pressure were measured during coronary angiography.Results The aortic SBP and PP,and radial SBP and PP were significantly higher in patients with coronary artery disease than in the normal subjects.Multiple regression analysis indicated that aortic PP,radial PP,and age were closely related to the severity of coronary lesions.Conclusion PP is an independent risk factor for the severity of coronary artery stenosis,and aotic PP is a better predictor.
