Abstract
To determine the relationship of BRS [baroreflex sensitivity] to age, ACI [arterial compliance index], TPRI [total peripheral resistance index] and MBP [mean blood pressure] and hypertension 61 male subjects 19-65 yr old, with MBP from 77-134 mm Hg, were investigated. Partial correlative analysis was used to hold individual variables constant so that the effect of each on a given BRS relationship could be observed. An independent and significant relationship was observed between BRS and age; BRS and ACI correlated significantly through the influence of age, TPRI and MBP; BRS and TPRI did not correlate; and a significant BRS-MBP relationship existed through the influence of ACI. The relationship of MBP to BRS was dependent on the influence of ACI. GPRI was not directly related to BRS. The relationship to MBP to BRS was dependent on the influence of ACI but age was independently related to BRS.
