Discovering and preventing   before symptoms appear

Often, medicine finds ways to treat diseases, such as hypertension, only when the symptoms are evident and it is too late. GTcardio is a pioneering digital health company that offers cutting-edge technologies and solutions for remote cardiac, respiratory, and sleep  monitoring.


With its user-friendly devices, advanced algorithms, and strategic partnerships, GTcardio is revolutionizing the way individuals manage their cardiovascular health, empowering them to take control of their well-being and enabling earlier detection and intervention for heart-related conditions.

Platform and Algorithms



Cardiovascular Diseases

Cardiovascular diseases (CVD), including myocardial infarction (heart attacks), strokes, and heart failure, are a leading cause of mortality and disability.

GTcardio CALM™ platform aims at preventing CVD, through early detection and treatment assessment.


The optimal time for detection is during sleep, when blood pressure (BP) exhibits significant fluctuations, particularly during REM sleep when skeletal muscle activity decreases. BP rises spontaneously in rapid, spike-like surges, lasting only seconds, which regular spot BP checks or Ambulatory BP Monitoring may miss. Monitoring includes additional factors like cardiac output, oxygen saturation, heart rate, motion, and respiration rate to identify causes.


 Sleep apnea-induced hypertension, which results from interrupted breathing during sleep and white coat hypertension, which occurs in medical settings due to anxiety, can mask actual hypertension,  potentially leading to under-diagnosis and requiring continuous measurements. 

Real-time feedback and coaching 

GTcardio  proprietary CALM™ bio-sensing system offers numerous advantages, including ultraflexibility, and surface mapping capability.


Integrated into wearables, its features enable a cost-effective, non-invasive hemodynamic monitoring solution that can be comfortably worn for extended periods without the need for highly skilled operators. This system has the potential to revolutionize personalized medicine by tracking specific hemodynamic parameters, facilitating cardiovascular disease screening, and providing personalized health information. In sports and performance monitoring, it helps optimize training programs and identify factors that may enhance or hinder an athlete's performance.


Neuro-degenerative diseases

Brain pathology biomarkers can be detected in blood after crossing the blood-brain barrier, altering the hemodynamic profile and contributing to neurological disorders like Alzheimer's.

GTcardio's CALM™ Monitoring  platform has the potential to detect early stages of reduced or asymmetrical Cerebral Blood Flow (CBF), which may lead to cognitive decline. CALM™ can estimate cerebral blood flow over time and volume, while also analyzing symmetry between cerebral hemispheres and carotid pulse shapes.


This pioneering approach could reveal AD-related changes at pre-symptomatic or early stages of the disease, benefiting the elderly population and improving healthy longevity. 

Telemedicine and Assisted Living 

CALM™ Platform enables medical staff  to develop tailored therapies for seniors in assisted living facilities, which  impose a significant financial burden due, primarily, to the extensive staffing requirements. These facilities rely on a well-trained staff, including professionals in nursing, emergency care, and medical services. In situations where residents require personalized attention, maintaining a low resident-to-caregiver ratio becomes essential to ensure adequate individualized care.

This is particularly significant for assisted living facilities that cater to individuals with Alzheimer's or dementia, as these conditions demand intensive care and attention from the staff.

GTcardio's solution is specifically targeted towards addressing the areas where patients experience significant unmet medical needs despite the existing scientific advancements.
