Hypertension is a disease state characterized by increased blood pressure (BP) associated with hemodynamic abnormalities, including elevated systemic vascular resistance index (SVRI); and altered cardiac index (CI). The objective of this study was to use noninvasive impedance cardiography (ICG) to evaluate hemodynamic characteristics of subjects with and without hypertension. ⋯ Hemodynamic parameters from ICG displayed significantly different hemodynamic profiles between hypertensive and nonhypertensive subjects. However, significant individual variation of hemodynamic status exists. Hemodynamic measurements with ICG characterize hemodynamic status and may be helpful in diagnostic, prognostic, and therapeutic decision making in hypertensive subjects.

Impedance cardiography (ICG), a noninvasive method of hemodynamic monitoring, is a useful tool in the care of critically ill patients. Use of this technology shows promise in the hemodynamic assessment of hypertensive stroke patients. This study describes the different ICG findings of patients with hypertensive stroke and correlates parameters with patient outcome. ⋯ In this population of hypertensive stroke patients admitted to the ICU, ICG showed an elevated SVRI and SVR and depressed CO, SV, and SI. In the ischemic stroke group, higher SVR and SVRI were associated with in-hospital death, whereas in the hemorrhagic stroke group, lower SVR and SVRI were associated with in-hospital death. The ICG may provide significant prognostic information in patients admitted with hypertensive stroke.
