Abstract		In this study the author attemps to establish the changing of the relative heart volume (RHV), systolic time intervals, resting heart rate (HR) and ventilatory tests according to heaxt failure severity. The study includes 106 patients with arterial hypertension, dilated cardiomyopathy, mitral valve disease and patients surviving acute myocardial infarction. The subjects were divided into four groups with respect to their New York Heart Association (NYHA) functional class. The results were compared with those in a group of 30 healthy volunteers from the control group. RHV, systolic time intervals PEPI and PEP/LVET and forced vital capacity (FVC) showed statistically significant differences as early as in the I. and II. NYHA functional class compared with the control group. LVETI, HR, FEV1/FVC and FEF 25-75% showed statistically significant differences in the III. and IV. NYHA functional class compared with the control group. RHVs are larger and airway obstruction is more prominenet in the III. and IV. NYHA functional class in the patients-with mitral valve disease and dilated cardiomyopathy. The heart failure index (HFI1) which includes measurements of RHV, PEP/LVET and FVC, and the heart failure index (HFI2) which includes measurements of RHF, HF and FVC showed a continuous increase of values from the I. to IV. NYHA functional class and statistically significant differences from the I. and II. NYHA functional class compared with the control group.
