本文用超声心功图对30例冠心病并发充血性心力衰竭(下称冠衰);患者的左室功能进行了动态研究。对冠衰患者在冠表时(Ⅰ)、冠衰使用强心药物后(Ⅱ),及冠衰基本控制(Ⅲ)三个时程以及23例正常人(NC)分别观测了11项指标,并进行统计学处理。结果EF、mVcf、△D、CDa、SV、Ds,IVSa、LVPWa八项指标在冠衰的监测,强心药物作用观察及左室功能转归的判断中均有明显价值(P<0.01或<0.001)。此外发现;(1)EPSSb是一项检出冠衰左室功能的极敏感指标,但在全程观察中存在某些局很性。(2)CDa和EPSSb/CDa可作为评价冠衰左室功能的新指标,其测定不受室壁节段性运动异常影响。本文还讨论了各项指标预测判断率。
In this paper, 30 patients with coronary heart disease congestive heart failure (hereinafter referred to as coronary heart failure); left ventricular function in patients with dynamic study. Eleven indicators were observed in patients with coronary heart failure at the time of coronary heart disease (Ⅰ), coronary heart failure (Ⅱ) and basal decubitus control (Ⅲ) and 23 normal subjects (NC) And statistical analysis. Results The eight indexes of EF, mVcf, △ D, CDa, SV, Ds, IVSa and LVPWa all had significant value in the monitoring of coronary heart failure, the observation of cardiac function and the judgment of left ventricular function outcome (P <0.01 or < 0.001). In addition, we found: (1) EPSSb is a very sensitive marker for detecting left ventricular dysfunction in coronary arteries, but there are some localities in the whole observation. (2) CDa and EPSSb / CDa can be used as a new index to evaluate the left ventricular function in coronary heart failure, and the results are not affected by abnormal segmental wall motion. This article also discusses the various indicators of predictive judgment.
