Abstract
A proportion of septic patients exhibit LV systolic dysfunction which easily underdiagnosed by conventional echocardiography, Strain imaging by either tissue doppler imaging (TDI), or by digital 2-dimensional speckle tracking echocardiography (STE) analysis have been reported to assess abnormal left ventricular LV contractility in sepsis. Assessment of LV strain, strain rate in different grades of sepsis by TDI,ST and Comparison between both approaches in relation to the survival outcome in sepsis. Thirtytwo patients, 13 pts.with sepsis (group I), 19 pts. with severe sepsis/septic shock (groupII) and a subset of 10 controls (groupIII) were included. APACHE II score was assessed on admission. In the first 24 hours, echocardiography derived LV dimensions and ejection fraction (%EF) were recorded in sinus rhythm,Apical 4-chamber (4-CH), Apical 2-chamber (2-CH) and Apical 3-chamber (3-CH) views were acquired in ECG-gated cine loops by two techniques, 2D and TDI for later off line analysis.STE and TDI were usedto acquire segmental strain& strain-rate during systole, which were averaged for the whole segments to obtain global results. Compared to controls, EF% of group I were comparable, 68.4±5.2 vs.69±4 but group II showedlower EF compared to groupI,and controls 63±5.63 but still preserved
