  • Ocena polnilnega tlaka levega prekata s tkivno doplersko ehokardiografijo = Assessment of left ventricular filling pressure using tissue Doppler echocardiography
    Tretjak, Martin
    Background Assessment of left ventricular (LV) filling pressure is often necessary in clinical practice, especially in hemodinamically unstable patients. Echocardiography enables non-invasive ... assessment of many hemodinamical parameters and with the use of tissue Doppler echocardiography (TDE) also LV filling pressure. The ratio between mitral valve early diastolicvelocity (E) and tissue Doppler mural annular early diastolic velocity (Em) is in very good correlation with pulmonary artery wedge pressure. In our study we tried to evaluate the E/Em ratio in unselected population of patiercts with heart failure. Methods 50 patients with heart failure and 30 healthy individuals were included in the study. Standard echocardiographic exam and pulsed wave tissue Doppler was performed of septal border of mitral annulus were performed in all participants. The E/Em ratio was calculated and values compared between both groups. The correlation between E/Em ratio and age was assessed in healthy subjects. Results The E/Em ratio was significantly higher in patients with heart failure then in healthy subjects. The cut-off value 11 had 85% sensitivity and 93% specificity in diagnosing heart failure. There was no statistically significant correlation between E/Em ratio and age. Conclusions By using TDE and E/Em ratio, we can confirm the presence of elevated LV filling pressure in patients with heart failure.
