Matching and haemodynamic parameters of patients with RA and matched healthy controls. Values represent means unless stated otherwise. p Values were determined by two tailed, paired t test. Only p values <0.05 are displayed
| Parameter | Patients with RA (n=14) | Healthy controls (n=14) | p Value |
|---|---|---|---|
| S-Cholesterol, random serum total cholesterol; PSBP, peripheral systolic blood pressure; PDBP, peripheral diastolic blood pressure; MPBP, mean peripheral systolic blood pressure; CSBP, central systolic blood pressure; CDBP, central diastolic blood pressure; CMBP, central mean blood pressure; AIx, aumentation index; SPTI, systolic pressure time integral; DPTI, diastolic pressure time integral; Tr, timing of the reflected pressure wave (see “Patients and methods” for definitions). | |||
