Abstract
High blood pressure (BP), or hypertension, is the main risk factor for cardiovascular diseases and the root cause for approximately ten million deaths each year. Its formal diagnosis often requires 24-hour ambulatory blood pressure monitoring (ABPM), with cuff-based BP measurements cycling at 20- or 30-minute intervals. The procedure can be quite obtrusive, particularly during nighttime, where the inflation of the cuff can disturb sleep and lead to non-representative BP readings. In the present study, we demonstrate the feasibility of using a cuffless optical watch-like sensor for 24-hour ABPM, paving the way for a new branch of cuffless and patient-friendly solutions in the thriving market of hypertension diagnosis.
