Résumé |
Objective |
Impaired vascular tone plays an important role in cardiogenic shock (CS) and constitutes a therapeutic target with vasopressor treatment. Echocardiography can provide a non-invasive estimation of systemic vascular resistance (SVR). The aim of the present study was to compare doppler echocardiography with the transpulmonary thermodilution (TPTD) method for the assessment of SVR in patients with CS.
Methods |
This prospective monocentric comparison study was conducted in a single cardiology intensive care unit (Hopital Nord, Marseille, France). We assessed systemic vascular resistance index (SVRi) by both echocardiography and TPTD in 28 patients admitted for CS, on admission and after introduction of an inotrope or vasopressor treatment.
Results |
A total of 35 paired echocardiographic and TPTD estimation of SVRi were compared. Echocardiography values ranged from 1309 to 3526 dyne-s-m2/cm5 and TPTD values ranged from 1320 to 3901 dyne-s-m2/cm5. A statistically significant correlation was found between echocardiography and TPTD (r=0.86, 95% CI 0.74; 0.93, P<0.0001). Intraclass correlation coefficient was 0.84 (95% CI 0.72; 0.92). The mean bias was −111.95 dyne-s-m2/cm5 (95% CI −230.06; 6.16). Limits of agreement were −785.86; 561.96.
Conclusion |
Doppler echocardiography constitutes an accurate non-invasive alternative to TPTD to provide an estimation of SVR in patients with CS.
