Affordable, easy to use technology for cardiovascular screeningNeed To overcome current barriers of expensive technology and high-end technical expertise
Stiffness of blood vessels has been established to be a very strong marker of cardiovascular problems and cardiac aging. Evaluation of arterial stiffness requires accurate measurement of changes in arterial dimensions and blood pressure. State of the art methods use specialised ultrasound imaging equipment to perform this measurement. The requirement of expensive technology and extensive technical expertise to use that technology, limits wide spread use of image-based arterial stiffness measurement. There is a need for an affordable, easy to use technology that can be deployed widely with minimal training.
HTIC has developed ARTerial Stiffness Evaluation for Non-invasive Screening (ARTSENS). It is an image-free technology for non-invasively measuring arterial stiffness in an automated manner. ARTSENS uses custom designed ultrasound probe integrated with proprietary intelligent signal processing to identify arterial anatomy, capture vessel wall dynamics and calculate clinically accepted measures of stiffness. Once the probe is placed over the neck, the device directly yields the stiffness measurement within 30 seconds. A hand-held cardiovascular screening device based on ARTSENS technology is currently under development.
A pilot study conducted in collaboration with MediScan Systems, Chennai on nearly 100 subjects validated the in-vivo measurements made using ARTSENS against a conventional ultrasound imaging system. ARTSENS device was used in a vascular screening camp conducted by Thambiran Heart and Vascular Institute, Chennai to measure arterial stiffness of more than 50 subjects within a period of about 4 hours. These pilot studies demonstrated ability of ARTSENS to measure arterial stiffness under in-vivo settings. The intelligence embedded in the technology allows personnel to use the device with minimal training. An extensive clinical study of ARTSENS is currently underway at Sri Ramachandra University, Chennai.
