Study of Relationship between Aortic Pulse Pressure and Severity of Coronary Artery Disease

Objective To evaluate the relation of the aortic pulse pressure to the severity of coronary artery disease. Methods Coronary angiography was performed in 268 patients. The aortic blood pressure and pulse pressure was measured by computer during coronary angiography. The degree of coronary artery disease was denoted with the coronary number of stenosis and the score of coronary lesion.Results Coronary artery narrow group its age, SBP, DBP, and PP comparison with coronary artery normal group difference has statistics significance(P0.01). But the age, SBP and PP increase gradually along with the narrow count increase.Pulse pressure≥60mmHg group three pathological change prevalence rate obviously markup, the difference has statistics significance(P0.01). Aortic pulse pressure and age were significantly related to coronary artery narrow degree.Conclusion Aortic pulse pressure was significantly related to coronary artery narrow degree. Aortic pulse pressure has the independent prospective value to the coronary artery disease.
