    A Comparison of Echocardiography and the Pressure Recording Analytical Method (PRAM) for Predicting Fluid Responsiveness after Passive Leg Raising
    (2021) Ozdemirkan, Aycan; Aitakhanoya, Manat; Gedik, Ender; Zeyneloglu, Pinar; Pirat, Arash; 0000-0002-7175-207X; ABI-2971-2020
    Objective: This study aims to assess the agreement between the cardiac index (CI) measured by pressure recording analytical method (PRAM) and transthoracic echocardiography (TTE) before and after the passive leg raise (PLR) maneuver. Methods: This is a prospective observational study in critically ill patients who were monitored with MostcareUp/PRAM (Vygon, Vytech, Padova, Italy). Cardiac index (CI) values and percent changes in CI values in response to PLR were recorded by TTE and PRAM. Results: Data of a total of 25 patients were collected. The median CI values that were calculated by TTE before and after PLR were 2.5 (1.2-4.7) L/min/m(2) and 2.9 (1.4-5.6) L/min/m(2), respectively. The median CI values that were calculated by PRAM before and after PLR were 2.5 (1.5-4.8) L/min/m(2) and 2.6 (1.7-5.7) L/min/m(2), respectively. There was significant correlations between the measured CI values both by TTE and PRAM before and after PLR (r=0.635, p=0.001 and r=0.610, p=0.001, respectively). The median percent changes in CI with TTE and PRAM were -0.13 (-0.7-0.4) and -0.11 (-0.5-0.5), respectively. Sixteen patients were determined as FR by TTE (64%) and 13 patients were determined as FR by PRAM (52%). The Kappa test showed moderate agreement between TTE and PRAM for predicting fluid responsiveness (k=0.595; p=0.002). The mean biases between the CI values measured by TTE and PRAM before and after PLR were 0.04 +/- 0.77 L/min/m(2) and 0.22 +/- 0.88 L/min/m(2), respectively. Conclusion: This study showed a significant correlation for CI values measured by both methods. For predicting fluid responsiveness there was agreement between the two methods after PLR.

    Comparison of Epicardial Fat, Carotid and Femoral Intima-Media Thicknesses Between Hypertensive, Pre-Hypertensive and Control Groups
    (2020) Gunesli, Aylin; Yilmaz, Mustafa; 0000-0002-2557-9579; S-6973-2016
    Objective: The aim of this study was to evaluate whether pre-hypertension is a risk factor for cardiovascular events. For this reason epicardial fat thickness (EFT), carotid intima-media thickness (CIMT) and femoral intima-media thickness (FIMT), known as markers for subclinical atherosclerosis and cardiovascular risks were measured and compared among the pre-hypertensive, hypertensive and control groups. Material and methods: This cross-sectional study included 57 healthy controls (group 1), 58 pre-hypertensive patients (group 2) and 56 hypertensive patients (group 3). Pre-hypertension is defined as systolic blood pressure (SBP) 120-140 mm Hg and diastolic blood pressure (DBP) 80-90 mm Hg. Hypertension is defined as SBP>140 mm Hg and/or DBP>90 mm Hg. EFT, CIMT and FIMT were measured and compared among these groups. Results: There was a statistically significant difference among the groups in terms of EFT and CIMT (p<0.001, for both comparison). In addition there was a statistically significant difference between groups 2 and 1, and between groups 3 and 2 in terms of EFT and CIMT (p<0.001, for all comparisons). When we compared the all groups in terms of FIMT, we found a statistically significant difference (p<0.001). There was a statistically significant difference between groups 3 and 2 (p=0.001). However, there was not a statistically significant difference between groups 2 and 1 (p=0.773). Conclusion: These results may indirectly suggest that subclinical atherosclerosis and cardiovascular risks may be increased in pre-hypertensive patients. However, atherosclerosis in the carotid arteries may be affected by lower blood pressure than the femoral arteries.
