    Abstract:
    OBJECTIVE: To observe the value of heart-type fatty acid-binding protein (H-FABP) and echocardiographic indexes in the diagnosis of cardiac insufficiency in sepsis. METHODS: A prospective observational study was conducted. Eighty patients with sepsis admitted to the department of critical care medicine of the First Affiliated Hospital of Medical College of Shihezi University from October 2016 to January 2018 were enrolled. General clinical data such as gender, age, acute physiology and chronic health evaluation II (APACHE II), sequential organ failure assessment (SOFA) score, hospitalization time and 28-day mortality were recorded. Echocardiographic indexes at 1, 3, 7, 10 days after diagnosis, and white blood cell (WBC), neutrophilic granulocyte percentage (N%), N-terminal pro-brain natriuretic peptide (NT-proBNP), serum H-FABP level were recorded. Sepsis patients were divided into normal cardiac function group (n = 30) and cardiac insufficiency group (n = 50) according to cardiac function, the differences of echocardiographic indexes and cardiac markers between the two groups at different time points were compared. Logistic regression was used to screen out cardiac ultrasound indexes and cardiac markers that affect the occurrence of cardiac dysfunction in sepsis patients, and then receiver operating characteristic (ROC) curve analysis was performed. RESULTS: Comparing the general data of the two groups, only the SOFA score of the cardiac insufficiency group was significantly higher than that of the normal cardiac function group (6.12±4.09 vs. 4.57±2.45, P < 0.05). N% and H-FABP in cardiac insufficiency group were higher than those in normal cardiac function group at the same time (N%: F = 6.973, P = 0.010; H-FABP: F = 17.303, P = 0.000). Without considering the time factor, there were significant differences in left ventricular end-diastolic volume (LVEDV), left ventricular end-systolic volume (LVESV), left ventricular ejection fraction (LVEF), stroke volume (SV), cardiac output (CO), left ventricular fractional shortening (LVFS), E-point of septal separation (EPSS), isovolumic relaxation time (IVRT), E peak deceleration time (EDT), A peak duration (Ad), left ventricular systolic pulmonary vein velocity (S), blood flow velocity of pulmonary vein in early left ventricular diastolic period (D), tricuspid orifice early diastolic blood flow velocity (E'), tricuspid orifice late diastolic blood flow velocity (A'), systolic velocities of the right ventricular free wall tricuspid annulus (Sm), and pulmonary valve annulus blood flow velocity (PVBV) between the two groups. ROC curve analysis of cardiac ultrasound indicators and cardiac markers screened by Logistic regression showed that the area under ROC curve (AUC) and the positive and negative predictive values were: LVEDV was 0.636, 77.30%, 56.03%; SV was 0.779, 88.82%, 71.19%; LVEF was 0.753, 92.12%, 55.21%; CO was 0.754, 88.82%, 77.19%; LVFS was 0.728, 81.25%, 66.99%; EPSS was 0.663, 96.99%, 51.56%; IVRT was 0.775, 86.97%, 73.55%; A' was 0.908, 96.58%, 89.60%; Sm was 0.738, 93.37%, 56.77%; H-FABP was 0.673, 80.26%, 57.25%, respectively. H-FABP was tested in parallel with LVEDV, SV, LVEF, CO, LVFS, EPSS, IVRT, A', Sm, and the positive predictive values were higher than the single diagnostic test (85.45%, 93.91%, 96.72%, 94.74%, 89.43%, 98.00%, 92.00%, 99.42%, 93.60%, respectively), the negative predictive values were lower than the single diagnostic test (50.89%, 57.93%, 49.15%, 58.18%, 57.05%, 45.74%, 57.92%, 64.13%, 47.78%, respectively). CONCLUSIONS: Cardiac ultrasound indicators LVEDV, SV, LVEF, CO, LVFS, EPSS, IVRT, A', and Sm combined with H-FABP are of certain value in the diagnosis of sepsis-associated heart dysfunction.
