  1. WatchBP Office ABI • Presenter: Willem Verberk • Date: 22/04/2010 Lacer, Barcelona, Spain Microlife www.microlife.com

  2. Microlife WatchBP Office ABI

  3. WatchBP Office ABI : vascular screening device • Ankle Brachial Index (ABI) • Inter Arm Difference (IAD) • Atrial Fibrilation screening (Afib)

  4. WatchBP Office ABI Display

  5. Cuffs provided with WatchBP ABI

  6. ABI measurement ABI= 148/136

  7. BPankle ABI = BParm Ankle Brachial Index (ABI)

  8. Validation Procedure: Observers • Two observers (A and B), assessed agreement in measuring SBP at the level of the brachial artery, the dorsalis pedis and the posterior tibial artery using a doppler device (5-10 MHz) • All measurements of each individual participant were performed by the same observer (A or B, according to their availability).

  9. Validation procedure A

  10. Arm selection IF IAD (consistently) >12 mmHg (Circulation 2006, ACC/AHA PDA guidelines) arm with higher BP is selected. Otherwise the right arm

  11. Validation procedure B

  12. Doppler measurements

  13. Artery compared

  15. Population • 93 patients • Age 62.5±11.1 years • Men 62% • Hypertension 83% • Diabetes 45% • Dyslipidemia 72% • Smoking 15% • cardiovascular disease 23%

  16. Results I WatchBP vs. Doppler • 1st measurement 1.08±0.17 vs. 1.11±0.17 • Difference of Doppler vs. WatchBP • 0.03 ± 0.11 (1st measurement) • 0.02 ± 0.10 (average of 2 readings) • 0.02±0.09 (average of 3 readings; p<0.01 for all). • Correlation Doppler and WatchBP • 0.80 (1st measurement ) • 0.84 (average of 2 readings) • 0.86 (average of 3 readings; P < 0.001 for all) • 95% Agreement diagnosing PAD (Doppler ABI <0.9)

  17. Results IIWatchBP vs. Doppler • WatchBP failed to measure ABI (5 sequential errors) in 3 legs. All with Doppler ABI <0.9. • Erroneous WatchBP readings more frequent in patients with PAD (35.2%) than without (5.7%) respectively, p<0.001). • The average time 3.8±0.3 vs. 8.8±2.2 min (p<0.001).

  18. Conclusion Validation study Automated ABI determination using Microlife WatchBP Office ABI is a quick, easy and reliable test for PAD detection Abstract ESH Oslo 2010
