Abstract

and various degrees of coronary artery disease E Klainman, A Landau, G Fink ‘‘GEFEN’’-Cardiac Health Center, Givatayim, ISRAEL Background Recovery indices of oxygen consumption (VO2) kinetics were observed as important factors to differ patients (pts) with various degrees of chronic heart failure (CHF). The significance of the relationship between such indices and various degrees of coronary artery disease (CAD) isn’t yet well established. Aim of study To find the relationship between recovery VO2-kinetics indices and various degrees of CAD, in comparison to normal individuals. Methods 70 pts, all men, were studied. They were divided in four groups according to their CAD degree as follows: Group A: Normal (control group; n = 20); Group B: one vessel disease (1VD; n = 26); Group C: 2VD (n = 12); and Group D: 3VD (n = 12). All pts underwent a cardiopulmonary exercise test (CPET) and the following recovery indices were measured: 1. half time recovery of VO2 (1/2tRec); 2. half time recovery of oxygen pulse (1/2Rec-O2P); and 3. total time recovery of VO2 (TtRec-VO2), till RER reached value of 1 or less.

E Klainman, A Landau, G Fink“GEFEN”-Cardiac Health Center, Givatayim, ISRAEL背景观察到氧消耗(VO2)动力学恢复指标是不同程度慢性心力衰竭(CHF)患者(pts)的重要因素。这些指标与不同程度冠状动脉疾病(CAD)之间关系的意义尚不明确。研究目的:通过与正常人的比较，探讨恢复vo2动力学指标与不同程度冠心病的关系。方法对70例男性患者进行研究。按冠心病程度分为4组:A组:正常(对照组;N = 20);B组:1支血管病变(1VD);N = 26);C组:2VD (n = 12);D组:3VD (n = 12)。所有患者均行心肺运动试验(CPET)，测定以下恢复指标:1。一半VO2回收率(1/2tRec);2. 氧脉冲半时间恢复(1/2Rec-O2P);和3。VO2的总恢复时间(TtRec-VO2)，直到RER达到或小于1。结果
