UNLABELLED: The objective of the investigation is to assess the safety and contribution of physical training in patients with chronic heart failure and to assess the effect of training on central haemodynamics, left ventricular function evaluated by echocardiography and humoral substances.
PATIENTS AND METHODS: Patients with cardiac failure NYHA II and III incl. 17 on t he background of IHD and 21 on the background of dilatation cardiomyopathy. All patients had the ejection fraction below 40% and pVO2 below 20 ml/kg/min. They were divided into groups enagaged in training (T) and controls (K). Before training and after its termination the patients were subjected to clinical examination, basic laboratory tests, echocardiography amd dextrolateral catheterization at rest and during ergometry and levels of humoral agents were assessed. The training was pursued three times per week for a period of two months on a bicycle ergometer.
RESULTS: Before training there were no statistically significant differences between the groups. After training the groups did not differ in echocardiographic and haemodynamic parameters. In the training group there was as compared with the onset of the experiment a decline of the maximal median pressure (123.6 +/- 11.9 vs. 113 +/- 10.2 mm Hg, p < 0.04) the maximal pulse rate (112.5 +/- 18.7 vs. 108.4 +/- 20.1 p
