Comparison of Office and Cuffless Ambulatory Blood Pressure-Guided Management in Patients With Hypertension (CUFFLESS)

17. srpna 2026 aktualizováno: Hae-young Lee, Seoul National University Hospital

Comparison of Clinical Outcomes Between Office and Cuffless Ambulatory Blood Pressure-guided Management in Patients With Hypertension

Hypertension is a major risk factor for cardiovascular and cerebrovascular diseases, including stroke and myocardial infarction. Blood pressure (BP) fluctuates throughout the day in response to physical activity, emotional states, and sleep. However, hypertension diagnosis and management are commonly based on BP measurements obtained in the clinic or at home, which may not fully reflect these variations. This can contribute to discrepancies between office and out-of-office BP, including white-coat and masked hypertension.

Ambulatory blood pressure monitoring (ABPM) provides information on BP throughout daily activities and sleep, but conventional cuff-based ABPM may be limited by discomfort, accessibility, and logistical challenges. Recently, cuffless wearable devices have enabled repeated BP monitoring without the use of a conventional inflatable cuff.

The CUFFLESS study is a multicenter, prospective, randomized controlled trial comparing two strategies for the management of hypertension: cuffless ambulatory BP-guided management and conventional office BP-guided management. Participants will be randomly assigned to either management strategy and followed for clinical outcomes. The primary objective is to determine whether hypertension management guided by cuffless ambulatory BP monitoring reduces the occurrence of cardiovascular events compared with management guided by conventional office BP measurements.
