- W2074890535 abstract "The aim of this study was to evaluate echocardiography-based indices of myocardial function and markers of vascular inflammation and endothelial dysfunction in the early phases of severe sepsis. Forty-five adult patients (67% women; age 51 ± 18 years; Acute Physiology and Chronic Health Disease Classification System II score, 23 ± 7) admitted to the intensive care unit up to 24 hours after fulfilling criteria for severe sepsis or septic shock were studied. Clinical, laboratorial (endothelin 1 [ET1], vascular cellular adhesion molecule 1), and echocardiographic data were collected within the first 24 hours and again 72 hours and 7 days after admission. Intrahospital mortality was 33% (15 deaths). Left ventricular (LV) dysfunction (LV ejection fraction <55%) was identified in 15 (33%) patients, whereas right ventricular (RV) dysfunction (RV tissue Doppler peak systolic velocity [RV-Sm] <12 cm/s) was present in 14 (30%) patients. LogET1 was increased in patients with LV dysfunction (2.3 ± 0.6 vs 1.8 ± 0.4 pg/mL; P = .01) and RV dysfunction (2.5 ± 0.5 vs 1.8 ± 0.4 pg/mL; P < .001) and had negative correlations with LV ejection fraction (r = −0.50; P = .002) and RV-Sm (r = −0.67; P < .001). Left ventricular end-diastolic diameter, RV-Sm, and diastolic dysfunction were able to discriminate survivors from nonsurvivors, and the combination of these parameters identified groups of very low and high risk. Both LV and RV systolic dysfunctions are prevalent in severe sepsis, being directly associated with markers of endothelial dysfunction. Left ventricular nondilation, RV dysfunction, and diastolic dysfunction seem related to poor prognosis in this scenario." @default.
