摘 要:目的探讨心血管疾病患者炎症因子超敏C-反应蛋白(hs-CRP)与摄氧效率斜率(OUES)的相关性。方法选择经皮冠状动脉介入治疗后患者17例,稳定型心绞痛21例,原发性高血压24例。采用症状限制性标准Bruce分级平板运动方案,同时测定摄氧量(VO2)、每分通气量(VE)。采用对数曲线拟合的方法 ,建立回归方程:VO2=a×lgVE+b,计算a为OUES值。应用全自动免疫散射比浊法检测血清hs-CRP。超声心动图测定左心室射血分数(LVEF)。结果血清lg(hs-CRP)与OUES75(r=-0.506,P<0.001)、OUES100(r=-0.567,P<0.001)、LVEF(r=-0.286,P<0.01)呈负相关。多元逐步回归分析显示,lg(hs-CRP)(β=-0.374,P=0.006)、身高(β=-1.854,P=0.036)、体重(β=-5.033,P=0.034)是OUES75降低的危险因素;lg(hs-CRP)(β=-0.396,P=0.003)、身高(β=-2.157,P=0.013)、体重(β=-5.912,P=0.011)是OUES100降低的危险因素。结论血清hs-CRP可能是反映心肺储备功能及左室收缩功能的有效标记物。Objective To investigate the relationship between high-sensitivity C reactive protein (hs-CRP) and oxygen uptake efficiency slope (OUES) in patents with cardiovascular disease.Methods Exercise tests,following a symptom-limited standard Bruce protocol with simultaneous respiratory gas-exchange measurements,were performed on a treadmill in 17 post-PCI patients,21 stable angina pectoris and 24 patients with essential hypertension (EH).The oxygen uptake (VO2),minute ventilation (VE) were determined.The OUES was derived from the relation between VO2 (ml/min) and VE (L/min) during incremental exercise and was determined by VO2=a×lgVE+b,where a = OUES.The OUES was calculated from data of the first 75% (OUES75) and 100% (OUES100) of exercise duration.The serum hs-CRP was measured by immunoassays,and the left ventricular ejection fraction (LVEF) was measured with echocardiography.Results OUES75 (r=-0.506,P0.001),OUES100 (r=-0.567,P0.001) and LVEF (r=-0.286,P0.01) were correlated with lg(hs-CRP).In stepwise multivariable linear regression models,lg(hs-CRP) (β=-0.374,P=0.006),body height (β=-1.854,P=0.036),body weight (β=-5.033,P=0.034)were independent risk factors of lower OUES75.lg(hs-CRP) (β=-0.396,P=0.003),body height (β=-2.157,P=0.013),body weight (β=-5.912,P=0.011) were independent risk factors of lower OUES100.Conclusion The serum leveles of hs-CRP may be the useful marker that reflecting cardiopulmonary functional reserve and left ventricular function.
