Accuracy of a Cuffless Photoplethysmography (PPG) Chest-Patch Monitor for 24-hour Ambulatory Blood Pressure Monitoring
This study aims to validate the accuracy and reliability of blood pressure (BP) estimates obtained over 24 hours using a PPG-based chest-patch device compared to the gold standard ambulatory blood pressure monitoring (ABPM) method using an upper arm cuff-based oscillometric BP device, in both hypertensive and normotensive individuals referred by their provider to undergo a 24-hours ABPM for clinical indication. The Awake/Asleep test, which is the primary test recommended for automated wearable cuffless BP devices that are cuff-calibrated (based on the 2023 European Society of Hypertension (ESH) recommendations for the validation of cuffless blood pressure measuring devices), will be conducted in this study. The secondary aim of the study is to assess the feasibility and convenience of the PPG-based device.
• Females and Males subjects 18 years or older (from all skin tones/colors)
• Scheduled for ABPM for hypertension screening, evaluation, or management
• Subjects capable of using an application temporarily downloaded (for the duration of the study) on a personal smart phone device or on a device provided by the study sponsor
• Subjects with Atrial fibrillation or Atrial flutter are eligible to participate if standard cuff-based ABPM monitor can capture blood pressure at initialization
