Lung fluid levels estimated by remote dielectric sensingTM values and invasive hemodynamic measurements

Abstract Background Remote dielectric sensing (ReDSTM) is a recently introduced non-invasive electromagnetic-based technology to quantify lung fluid levels (Figure 1A). The association between ReDS values and invasively measured hemodynamics, particularly among those with small body size, remains uncertain. Methods Consecutive patients chronic heart failure who were admitted our institute underwent right catheterization as well simultaneous measurement at clinically stable conditions Sep Nov 2021 prospectively included. correlation PCWP was investigated. Results A total of 30 (median 79 [73, 84] years old, 13 men) Median value 26% (22%, 28%). had moderate (r=0.698, p<0.001; Figure 1B), even height <155 cm. cutoff 28% predicted >15 mmHg sensitivity 0.70 specificity 0.75. Conclusions might be promising tool estimate cardiac pressure in failure, smaller size. Funding Acknowledgement Type funding sources: None.
