Abstract

Background: Reduced heart rate variability (HRV) is a risk factor for cardiac death. Animal studies have shown increased HRV and reduced mortality after physical training. We evaluated the change in exercise capacity and HRVin cardiac rehabilitation patients, randomised to routine or home-based intensive training. The design was prospective, stratified randomisation withpre-specified subgroup analysis. Methods: Maximal bicycle exercise test and 24-h Holter were performed 1 (baseline). 4 and 12 months after myocardialinfarction (MI) or coronary artery by-pass surgery (CABG). Patients were randomised to physical training either two (N) or six (I) times per week for3 months Sixty-two patients (43 MI and 19 CABG patients) were evaluated. Results: Exercise capacity increased significantly more after 3 months of training in group I (mean ((S.E.); 29.0 (3.4) vs. 7.2 (2.6) watts, P < 0.001). One year later the difference in exercise capacity remained (26.5 (3.3) vs. 11.8 (3.8) watts, P < 0.001). Global HRV measurements SDNN and SDANN increased significantly more in group I after training (17.1 (5.6) vs. 1.7 (3.7) and 16.2 (4.9) vs. 2.8 (3.1) ms, P < 0.05) and 1 year later the differences were still significant. Subgroup analysis showed more pronounced HRV response in CABG than MI patients. Conclusion: Intensive exercise training incardiac rehabilitation increases exercise capacity and global HRV, which could be of prognostic significance. (C) 2001 Elsevier Science Ireland Ltd.
