Objectives:
Elevated central blood pressure (BP) and arterial stiffness are risk factors for cardiovascular mortality. However, their prognostic value in patients with hemodynamic shock has not been studied broadly. Evolved BP monitoring devices enable the noninvasive assessment of central BP and arterial stiffness. The objective of this study was to evaluate the prognostic value of central BP and arterial stiffness measurements, delivered by 2 noninvasive devices, in patients with septic or cardiogenic shock admitted to the intensive care unit.
Design:
This is a monocenter, prospective, cohort study.
Setting:
This study was conducted in a tertiary university hospital.
Participants:
We enrolled 57 patients who were admitted to the intensive care unit with septic or cardiogenic shock.
Interventions:
None.
Measurements And Main Results:
Central BP and arterial stiffness indices like pulse wave velocity (PWV) and Aix were recorded with a Mobil-o-Graph 24h PWA and SphygmoCor XCEL. Age, catecholamine dosage, resuscitation incidence before inclusion, C-reactive protein, leukocytes, and creatinine were recorded as possible confounders. With regard to the confounders, central systolic BP measured in the first 24 hours, was predictive of 6-month mortality (odds ratio, 0.9; p < 0.05). Aix, recorded by Mobil-o-Graph 24h PWA, was associated with death in the first 14 days (odds ratio, 1.11; p = 0.03). An increased PWV was not associated with adverse outcomes.
Conclusions:
Low central BP and increased Aix were linked to a higher mortality in shock patients. PWV had no prognostic value.

Monitoring Both Arms:
Monitoring BP in both arms during the initial assessment is advisable, as the systolic value may differ by five to ten mm Hg between arms. For subsequent BP assessments, use the arm with the higher reading.

Blood Pressure: Hypertension and Hypotension
Normal blood pressure is 120/80 mm Hg. Elevated blood pressure is 120-129/under 80 mm Hg. Hypertension, warranting treatment at 130/80 mm Hg, is often asymptomatic and can lead to severe cardiovascular events, aneurysms, peripheral arterial disease, chronic renal disease, or cardiac...
