“Tracking blood pressure over long periods without alerting the patient represents a potential game-changer in the diagnosis and monitoring of hypertension.”

Dr. Neil Poulter

Imperial College London
Professor of Preventative Cardiovascular Medicine
Former President of the British and Irish Hypertension Society 

quote

“As the principal investigator of Aktiia’s pivotal clinical trial, I am pleased that the result of our study shows that Aktiia solution is accurate and allows patients and physicians to track their blood pressure daily. I believe Aktiia solution has the potential to change the management of hypertension.”

Dr. Grégoire Wuerzner

University Hospital of Lausanne Switzerland
Head of Hypertension Unit
President, Swiss Society of Hypertension

quote

“The ultimate tool for hypertension evaluation and management is going to be: a cuffless beat-to-beat ambulatory blood pressure monitor which is able to provide the full 24-hour profile of blood pressure during routine conditions and activities for several days.”

Insight

Why Does 24/7 Blood Pressure Matter?

Decades of clinical research support the importance of:

  • More frequent, accurate blood pressure measurements at home
  • Measurement of nighttime blood pressure to assess cardiovascular risk
  • Adjustment of medication titration based on blood pressure changes
  • The impact of lifestyle changes like diet, exercise, or meditation on blood pressure control.
