The prognostic value of impedance cardiography (ICG; cardiac index [CI] and systemic vascularresistance index [SVRI] were measured) was assessed in this retrospective cohort study. A totalof 1151 hypertensive outpatients 450 years with a baseline ICG were included. After medianfollow-up of 3.9 years, for the composite endpoint of cardiovascular events and stroke, adjustedHR for each 500 ml/min/m2 CI increase was 0.85 (CI95% 0.73?0.9, p ¼ 0.039), and for each 500dynes s cm5 SVRI increase was 1.11 (CI95% 1.01?1.23, p ¼ 0.046), whereas adjusted HR for allcause mortality was not significant. ICG adds prognostic value to conventional risk factors inhypertensive patients.
