Heart failure (HF) is determined by pathophysiologic changes in the left ventricle (LV) that occur before the onset of clinical symptoms; these changes can lead to mitral insufficiency that will maintain and favor ventricular dysfunction. An associated change in contractility occurs which will maintain the vicious circle. 252 patients with HF were included in this cross-sectional analysis. Patients were divided into two groups, Group I-S/V (n = 55) and Group II-CT (n = 197) to comparatively assess cardi-ac parameters according to the administered therapy and to determine their correlation with quality of life domains. 2D measurements were performed to determine ultrasound parameters. The WHOQOL-BREF questionnaire was used to assess the quality of life. When analyzing the mean values of the determined echocardiographic parame-ters, significant differences in LV ejection fraction (LVEF) (p < 0.03) Results: Analysing the mean values of the echocardiographic parameters determined, significant differences in LV ejection fraction (LV ejection fraction (LVEF) (p < 0.001) and right ventricular diameter (p = 0.030) were found between the two study groups. The incidence of aortic regurgitation and tricuspid regurgitation was higher in the I-S/V group (40% vs. 25%, p = 0.001, respec-tively 47% vs. 35%, p = 0.03). Mitral regurgitation was present in relatively similar per-centages. Testing the association of echocardiographic parameters with quality of life do-mains showed a significant association of LVEF with physical health and relationship with the environment (p = 0.002, r = 0.143, respectively p = 0.041, r = 0.129). Physical dimension and relationship with the environment are more affected in pa-tients with low LVEF. Routine echocardiographic evaluation is essential in the global as-sessment of the HF patient and may suggest a low quality of life with impaired physical dimension.
