Correlation of invasive central arterial pressure with peripheral arterial pressure and coronary sclerosis / 中华老年医学杂志

ABSTRACT

Objective To study the consistency among non-invasive and invasive brachial artery pressure,radial artery pressure and invasive central arterial pressure,and to explore the correlation between the severe degree of coronary artery disease and invasive central aortic pressure.Methods A total of 331 patients who underwent coronary angiography in our hospital were selected.The invasive central aortic pressure,invasive and non-invasive brachial arterial pressure,radial artery pressure in all patients were measured.The severe degrees of atherosclerosis were recorded.The differences among invasive brachial arterial pressure and invasive radial artery pressure,non-invasive brachial artery pressure and non-radial artery pressure and invasive central aortic pressure were compared.Results The systolic pressure values measured in invasive and non-invasive brachial artery and radial artery were higher than that measured by central aortic pressure,while the diastolic pressure values measured in the four peripheral artery were lower than that measured in central aorta.The pressure values measured by non-invasive brachial artery pressure were more close to that measured by invasive central aortic pressure (P＞0.05).The systolic pressure was increased and the diastolic pressure was reduced in central aortic pressure with the coronary vessel lession numbers increased.The values of systolic pressure in patients with single-vessel,double-vessel and triple-vessel lesions were (118.2± 19.5) mm Hg,(124.9 ± 19.7) mm Hg and (137.7 ± 20.6) mm Hg,respectively and the values of diastolic pressure were (86.8±8.4) mm Hg,(85.3± 10.3) mm Hg and (83.1± 9.4) mm Hg,respectively.There were significant differences in systolic and diastolic pressure values among patients with single-vessel lesions,double vessel lesions and triple-vessel lesions(F=3.93,4.31,both P＜ 0.05).Conclusions The blood pressure values measured by noninvasive brachial artery pressure are more close to that measured by invasive central aortic pressure.There is a significant correlation between the severe degree of coronary heart disease and invasive central aortic pressure.Non invasive brachial artery pressure can be used in the early detection of cardiovascular dysfunction.
