摘要:
目的 通过对老年慢性心力衰竭患者无创血流动力学监测，并与美国纽约心脏病学会（NYHA）心功能分级做对比分析，初步评价判定心功能分级的可靠性。方法 选取我院自2004年4月~2005年9月1日收治于老年心血管病科的冠心病、高血压病、扩张型心肌病等患者共120例，按NYHA分级分为Ⅰ、Ⅱ、Ⅲ、Ⅳ共4组，应用Bioz.com无创血流动力学监测得到16种血流动力学参数，进行统计学分析。结果 ①心输出量（CO）、心排血指数（CI）、左室每博作功指数（LVSWI）、左心作功指数（LCWI）4项参数值按NYHA分级Ⅰ~Ⅳ组有逐渐减低趋势（P<0.05）；②每博输出量（SV）、每博输出指数（SI）、速率指数（VI）按NYHA分级Ⅰ、Ⅱ组间，Ⅲ、Ⅳ组间无显著差异，但Ⅰ、Ⅱ组与Ⅲ~Ⅳ组间有明显减低趋势（P<0.05）；外周阻力（SVR）、外周阻力指数（SVRI）按NYHA分级Ⅰ、Ⅱ组间，Ⅲ、Ⅳ组间无显著差异，但Ⅰ、Ⅱ组与Ⅲ、Ⅳ组间有明显增高趋势（P<0.05）；③胸部液体含量（TFC）、收缩时间比率（STR）按NYHA分级Ⅰ、Ⅱ、Ⅲ组间无显著差异，但Ⅳ组与其他各组比较有明显增高趋势（P<0.05）。结论 无创血流动力学监测到的血流动力学参数可作为评估慢性心力衰竭临床分级标准的量化指标。
Abstract:
AIM To evaluate the clinical scale of chronic heart failure by impedance cardiography in elder chronic heart failure patients and to determine the corresponding quantitative parameters with NYHA cardiac functional grading. METHODS One hundred and twenty patients (with coronary artery disease, hypertensive heart disease, dilated cardiomyopathy) were divided into I, II, III and Ⅳ group according to NYHA cardiac functional grading. Sixteen hemodynamic parameters were detected with Bioz. com impedance cardiography equipment. RESULTS ①Cardiac output (CO), Cardiac index (CI), LVSWI and LCWI were found gradually decrease following the NYHA cardiac functional grading in I  Ⅳ group (P<0.05); ② SV, SI and VI were not significantly different between NYHA I and II, and between NYHA III and Ⅳ, but there was a significant decreasing tendency between NYHA I, II and III, Ⅳ (P<0.05). SVR and SVRI were not significantly different between NYHA I and II, and likewise between NYHA III and Ⅳ, but there was a significant increasing tendency between NYHA I, II and III and Ⅳ(P<0.05); ③ Thoracic liquid content (TFC) and systole time ratio (STR) were not significantly different between NYHA I, II and III, but there was a significant increasing tendency between Ⅳ and others (P<0.05). CONCLUSION Quantitative parameters with impedance cardiograph can be used to evaluate clinical cardiac function scale of chronic heart failure.
