本文报道了218例60～83岁老年人心脏收缩时间间期测定和染料稀释曲线测心输出量的结果。包括正常、冠心、高冠、心梗四组。冠心组的心脏指数减少射血前期延长,P/L比直增高,与正常组有显著差异。示此改变是估计左室功能降低心肌缺血的重要指标。高冠组的心输出量、心脏指数、主动脉顺度减低,周围血管阻力、平均动脉压增高,射血前期延长,P/L比值增大,与正常组有非常显著差异。示左室收缩功能低下,后负荷增大。心梗组心脏指数等明显降低,尤以LRT延长为著,Q/E—0达17,27％,有非常显著差异,示左室顺应性降低,左室舒张末期压力增高。
This paper reports the results of measuring cardiac contractile time interval and measuring the cardiac output of dye dilution curve in 218 elderly people aged 60 to 83 years. Including normal, coronary heart, crown, myocardial infarction four groups. Coronary heart index decreased prolonged ejection, P / L ratio increased, with significant difference between the normal group. Showing this change is an important indicator of left ventricular function to reduce myocardial ischemia. Cardiac output, cardiac index, decreased aortic compliance, peripheral vascular resistance, increased mean arterial pressure, prolonged ejection duration, and increased P / L ratio were significantly different between the high crown group and the normal group. Systolic left ventricular dysfunction was shown, after the load increased. Myocardial infarction group, such as cardiac index decreased significantly, especially in LRT prolonged as Q / E-0 up 17,27%, there is a very significant difference, showed reduced left ventricular compliance, left ventricular end diastolic pressure.
