The Relation Between Pulse Pressure,Serum Uric Acid and Total Bilirubin and the Severity of Coronary artery in Elder People
Objective To investigate the relationship between total bilimbin(TBil), serum uric acid(SUA), C-reactive protein(CRP) and the severity of coronary artery and its steadiness in elder people.Methods According to coronary angiography, one hundred seventy-eight elder patients divided into two groups: The coronary heart disease(CHD) group and non-CHD group(control group). The CHD group were further divided into three subgroups: single vessels(SV)disease group, double vessels(DV) disease group and multi-vessels (MV)disease group. The level of TBil , SUA and CRP were measured, and to analyze the relation between TBil ,SUA and ERr and the severity of coronary artery and its steadiness.Results The levels of SUA and CRP in CHD groups were significantly higher than that of control group(P0.05), The level of TBil in CHD groups was significantly lower than that of control group (P0.05). Those with higher SUA and CRP , and lower TBil showed more severe the Severity of coronary artery. The levels of SUA and ERr positively and the level of TBil negatively related with severity of coronary artery (P(0.05). compare with stable pathology group, The levels of CRP were significantly higher and the level of TBil was significantly lower in unstable pathology group, but the levels of SUA was not significant (P0.05).Conelusion The levels of elevated SUA and CRP, reduced TBil are closely related with CHD and the severity of coronary artery. The higher level of SUA, CRP and the lower level of TBil maybe were independent risk factor for CHD and the severity of coronary artery in elder patients.
