Evaluation of 24-Hour Arterial Stiffness Indices and Central Hemodynamics in Healthy Normotensive Subjects versus Treated or Untreated Hypertensive Patients: A Feasibility Study

Figure 1

Daytime and nighttime reflected wave transit time (RWTT), aortic pulse wave velocity (PWV), peripheral and aortic augmentation index (AI), and central (aortic) systolic (SBP) and diastolic blood pressure (DBP) values in healthy controls (open bars) and hypertensive patients (gray bars). For RWTT, PWV, and AI not normalized and normalized data (corrected for SBP and/or heart rate) are represented. Data are shown as averages and 95% confidence intervals for crude estimates (a) and for adjusted estimates ((b) data adjusted by age, gender, body mass index, antihypertensive treatment, and 24-hour SBP and DBP). The asterisks indicate the level of the statistical significance of the difference between the two study groups (; ; ).
