【摘要】 本文对４８例高血压病合并左室肥厚的红细胞聚集性进行研究，其中心肌缺血组２７例，无心肌缺血组２ｌ例.结果示：心肌缺血组红细胞聚集指数（ＲＢＣＡｌ）和低切变率下的全血粘度（ＷＢＶ５．７５_－ｓ）显著高于无心肌缺血组和正常对照组.ＲＢＣＡＩ＞ｌ００ｓｔ．ｐｖ．Ｈｔ_ｍｍ／ｈ者，心肌缺血组１９例，占７０．５％；无心肌缺血组仅６例，占２８．５％，两组差别显著.２４ｈ心电监测，心肌缺血发作总时间与ＲＢＣＡＩ成正相关（ｒ＝０．６７，ｐ＜０．０２５）．提示高血压合并左室肥厚中，红细胞过度聚集可能是诱发心肌缺血的重要因素之一.更多还原

【Abstract】 The changes of red blood cell aggregation in patients witn hypertensive heart disease havebeen observed, among them, myocardial ischaemia group(MIG) 27 patients, no myocardial ischaemiagroup( NMIG)21 patients。 The results show that(1) Whole blood viscosity at a shear rate of 5.57-s(WBV 5.57-s)and red blood cell aggregation index(RBCAI)in MIG are signicantly higher thanthat in NMIG。(2) In patients with more than l00 st.pv.Ht.mm/h in RBCAI, significant differencescan be found in tow groups,19 cases(70.5%) in MIG and 6 cases(28.5%) in NMIG。(3)Resistandtime of myocardial ischaemis in 24 hours ECG monitor is postively related to RBCAI(r=0。67.P<0.025). It suggested that excesive aggregation of red blood cell is one of the important factorsinducing myocardial ischaemia in hypert ensive patients with left ventricular hypertrophy。更多还原
