[Validation of a new impedance cardiography device for noninvasive hemodynamic measurement in outpatient hypertensive patients]
Objective: To compare the new cardiograph ZLogic for non-invasive measurements of Stroke volume (SV) and Cardiac output (CO) against the Minnesota cardiograph.
Methods: 86 subjects from both genders, 18-80 years old, hypertensive and healthy volunteers were included. Three hemodynamic measurements performed with each device, in an alternate fashion, using the Bland-Altman method to determine the level of agreement. Percentage error was calculated for interchangeability of both methods.
Results: Mean SV was 86.71±27.35 mL and mean CO 5.42±1.74 L/min. There was a strong correlation between measures of SV and CO obtained with both devices (r=0.99, p<0.001). Mean difference (MD) for SV was 0.65±3.08 mL (CI95%: -0.01-1.31) and 95% limits of agreement −5.39 to +6.69 mL. MD for CO was 0.05±0.17 L/min (CI95%: 0.01-0.09) and the 95% limits of agreement −0.28 to +0.38 L/min.
Conclusion: ZLogic and Minnesota cardiographs provided equivalent SV and CO values in ambulatory hypertensive patients.
