245 Peripheral Arterial Occlusive Disease Screening By An Automated Blood Pressure Monitor

Planas Adriana
Aim: To establish the feasibility of an oscillotonometric automated blood pressure monitor (ABPM) to detect peripheral arterial occlusive disease (PAOD) in general practice or in epidemiological surveys.
Design: case-control
Subjects: 60 adults (120 lower limbs) recruited from a general hospital vascular laboratory and 60 age/sex matched subjects recruited from a primary care centre.
Ankle and arm systolic blood pressures measured by 1) continuous Doppler device and sphygmomanometer (standard method), and 2) Omron 711 ABPM. Ankle-brachial indexes (ABI) were then calculated (2 ABI/limb for the Doppler method and 1 ABI/limb for the ABPM method). PAOD was defined by Doppler ABI1.5 were excluded.
Results: The ABPM allowed to obtain a numeric ankle blood pressure reading and thus to calculate ABI in 36/79 (45.6%) of PAOD limbs, and in 153/158 (96.8%) of normal limbs. An important correlation (intraclass correlation coefficient and paired student-t test) was observed between ABPM ABI and the highest Doppler ABI of the ankle. The ABPM showed an error message in 48 limbs of which 43 had PAOD. Categorized ABPM measurements (PAOD suspected if ABPM ABI99%, respectively.
An ABMP may help to screen PAOD quickly and operator-independently by ruling out the disease in >3/4 of adult general population.
