Abstract:
Objective To investigate the changes of capacitive arterial compliance(C1) and oscillatory arterial compliance (C2) in elderly patients with the coronary atherosclerosis and the coronary heart disease (CHD)and to study the association between Gensini Score and C1 or C2.MethodsElderly subjects (160 cases) were divided into three groups according to the results of selective coronary angiography: the normal,the coronary atherosclerosis and the CHD group. C1 and C2 were measured using a DO-2020 cardiovascular profiling instrument.The stenosis severity of coronary artery diseases was assessed using a scoring system called Gensini score. Bivariate analyses were performed to study the association between Gensini Score of coronary artery and each of C1 and C2.Results C2 in the coronary atherosclerosis group was significantly lower than that in the normal group, and higher than in CHD group. C1 had no statistically difference among the three groups. Gensini integral in the coronary atherosclerosis versus the CHD groups were ( 5.4+2.6) vs.( 51.3+ 32.1), respectively (t= 10.574, P＜0.01). Gensini Score in the coronary atherosclerosis group had no relation with C1, and was negtively correlated with C2. ConclusionsC2 is decreased in the early stages of the coronary artery atherosclerosis in elderly patients, and may help the identification of early coronary atherosclerosis.
