摘 要 目的 探讨冠心病患者血浆心钠素(ANF)与左房血流动力学变化的关系。方法 应 用超声心动图技术和放射性免疫测定法,对106例冠心病患者左房血流动力学变化与ANF水平进行 相关性分析。结果 心绞痛组、心肌梗塞组及缺血性心肌病组的ANF水平显著高于正常对照组;并 与左房功能指标LAV、LAT、LAP、LAD、LASV 和LAEF呈高中度线性相关意义;与左室收缩及舒 张功能指标:LVEF、LVD、PFR、A峰、A/E呈中度线性相关意义(P<0.01~0.001)。结论 测定 ANF水平对于评价左房室功能异常变化有重要意义。 关键词 冠状动脉疾病/血液;冠状动脉疾病/诊断;钠/代谢;超声心动描记术 中图号 R541.4
Plasma Level of Atrial Natriuretic Factor and Changes of Left Atrial Function in Patients with Coronary Heart Disease Tong Xiaoming,Sun Baozhen,Gao Qingping,et al. Zibo City Hospital,Zibo,255036 Abstract Objective To investigate the relationship between plasma atrial natriuretic factor(ANF) levels and changes of left atrial hemodynamics in patients with coronary heart disease (CHD). Methods Plasma ANF level and left atrial function as well as the changes of hemodynamics in 106 patients with CHD and 50 normal control (NC) group were measured by two dimensional Doppler echocardiography and radioimmunoassay.Results The plasma level of ANF concentrations in 36 angina pectoris(AP) group, 40 myocardial infarction(MI) group and 30 ischemic cardiomyopathy (ICM) group was higher than NC group (P?.01 or 0.001).Significant linear correlation existed between plasma level of ANF and the indexes of left atrial function:left atrial volume(LAV), left atrial tension (LAT),left atrial pressure(LAP),left atrial diameters( LAD),left atrial stroke volume(LASV) and left atrial ejection fraction(LAEF);the correlation coefficients were 0.79,0.74,0.69,0.682,0.66, 0.64 (P<0.01 or 0.001).Moderate linear correlations existed between plasma level of ANF and left ventricular systolic or diastolic function indexes: left ventricular ejection fraction (LVEF),left ventricular diameters ( LVD) ,peak filling rate (PFR),peak velocity A and A/E ratio: the correlation coefficients were -0.60,0.58,-0.[1] [2] 下一页 上一个医学论文: 应用SPECT观察激素对股骨头血流动力学影响的实验研究 下一个医学论文: 共焦镜同时检测细胞内Ca2 和pH的变化
