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.
