Key result
Impedance cardiography combined with NT-BNP testing identified left ventricular dysfunction in hypertensive patients with an area under the ROC curve of 0.73.
Why the study?
Do BNP, NT-BNP, and impedance cardiography accurately identify left ventricular dysfunction in hypertensive patients?
Observational (n=193)

Combined testing may aid noninvasive LV dysfunction detection in hypertension; leaves open prospective validation before clinical adoption.
Bhalla et al. (2005) conducted an observational in Hypertension (n=193). BNP, NT-BNP, and Impedance cardiography (ICG) was evaluated on Detection of left ventricular dysfunction (AUC 0.73 (ICG + NT-BNP)). Impedance cardiography combined with NT-BNP testing identified left ventricular dysfunction in hypertensive patients with an area under the ROC curve of 0.73.
