摘要
The prognostic value of impedance cardiography (ICG; cardiac index [CI] and systemic vascular resistance index [SVRI] were measured) was assessed in this retrospective cohort study. A total of 1151 hypertensive outpatients >50 years with a baseline ICG were included. After median follow-up of 3.9 years, for the composite endpoint of cardiovascular events and stroke, adjusted HR for each 500 ml/min/m2 CI increase was 0.85 (CI95% 0.73–0.9, p = 0.039), and for each 500 dynes s cm−5 SVRI increase was 1.11 (CI95% 1.01–1.23, p = 0.046), whereas adjusted HR for all-cause mortality was not significant. ICG adds prognostic value to conventional risk factors in hypertensive patients.
