HeartSentry: Personal Cardiovascular Health Monitor 

A simple and effective device that accurately measures the function of the endothelium. 

Blood pressure, pulse and endothelial function deliver unparalleled data
Blood pressure, pulse and endothelial function deliver unparalleled data. Design concept – not currently available for sale.

HeartSentry is designed to efficiently measure increases in arterial volume which occur when the endothelial cells of the artery are stimulated, and the muscles in the wall of the artery relax.

A proprietary blood pressure cuff utilizes specialized algorithms to interpret changes in the volume of blood in the arm. In a relaxed, dilated artery, the volume change over the cardiac cycle is much greater than baseline levels, typically by more than 80% in healthy subjects.

The HeartSentry inflatable cuff is outwardly identical to a standard blood pressure cuff, but is differentiated by its advanced firmware and software which operates a patent-protected measurement protocol.

The fully automated device is compact and inexpensive enough for commercial use in the home care market and primary care physician offices. Its integrated Bluetooth technology can communicate with nearby smart applications which can act as a portal to cloud-based technologies enabling advanced ongoing monitoring opportunities between patient and clinical care providers.

Research Results

Initial studies with 50 patients demonstrated a strong correlation to ultrasound results. The diagnostic value of the measurement is supported by thousands of peer-reviewed studies.
