Abstract

Background: The ABCD2 score is a clinical tool currently categorising transient ischaemic attack (TIA) patients as low or high risk. Arterial stiffness, a novel physiological parameter predicting future cardiovascular events, has not been explored in TIA populations.

Methods: The following arterial stiffness parameters were measured in TIA patients aged >40 years: carotid-femoral pulse wave velocity (C-F PWV), carotid-radial pulse wave velocity (C-R PWV) using Complior® and central and peripheral blood pressure (BP) using Arteriograph®. Nocturnal BP dipping profiles were measured using 24-h ambulatory blood pressure monitoring. TIA participants were age- and gender-matched with healthy subjects to compare arterial stiffness and BP profiles.

Results: Twenty-four TIA patients, 50% male, of mean±SD age 70±10.1 years were recruited to the study. Mean±SD C-F PWV was 11.5±3.18 m/s and C-R PWV was 10.8±1.26 m/s. Published normative data for healthy age- and gender-matched subjects are C-F PWV 10.9 m/s and C-R PWV 10.1 m/s. Our TIA patients had higher central (130 mmHg) than peripheral BP (128 mmHg) compared with healthy subjects in whom central BP is 10–15 mmHg lower than peripheral BP. Thirty-eight percent of TIA patients lacked nocturnal dipping compared with 19% of healthy subjects.

Conclusions: In our TIA cohort we found increased arterial stiffness measurements compared to healthy subjects.
