LightHearted AI: Revolutionizing Cardiac Diagnostics
LightHearted AI (formally LightHearted AI Health Limited) is a deep-tech medical device company headquartered in London, United Kingdom. Founded in 2023 by Dr. Lucrezia Cester and Dilip Rajeswari, the company is a spin-out from the University of Glasgow and the NHS Clinical Entrepreneur Programme. LightHearted AI is at the forefront of "contactless cardiology," utilizing quantum photonics and artificial intelligence to diagnose cardiovascular conditions remotely. The company?s mission is to close the diagnostic gap in heart disease, particularly for women and underserved populations who are historically more likely to be misdiagnosed.

Core Technology: The LightScope Platform
The technical foundation of LightHearted AI is a proprietary laser-based optical technology called LightScope. This system eliminates the need for physical contact between the clinician and the patient, using advanced photonics to capture vital cardiac biomarkers through skin and clothing.
1. Laser-Based Biomarker Acquisition
The system utilizes a high-speed camera and a laser beam aimed at the patient's neck. It records subtle vibrations of the main artery at approximately 2,000 frames per second. This "optical stethoscope" captures data that is often too faint for traditional acoustic stethoscopes to detect, providing a signal-to-noise ratio up to four times greater than standard tools.
2. AI-Driven Signal Processing
Traditional light-based sensors often struggle with varying skin tones, as different pigments reflect light differently. LightHearted AI has developed AI algorithms that are specifically trained to be skin-tone agnostic, ensuring that biomarker readings are accurate regardless of a patient's race or ethnicity. The AI component filters out "noise" such as breathing or chest movements, focusing exclusively on cardiac vibrations.
Products and Services
LightHearted AI offers a point-of-care diagnostic ecosystem designed to integrate into existing healthcare workflows?from GP surgeries to home monitoring.
1. LightScope Diagnostic Device
The LightScope is the company's flagship hardware. It is a non-invasive, touchless tool that can be operated by a medical assistant during routine vitals collection.
* 10-Second Diagnosis: The device captures heart sounds, ECG-equivalent data, and blood pressure, providing an AI-assisted diagnostic report in just ten seconds.
* Valve Disease Detection: It is specifically optimized to detect asymptomatic heart valve disease, a condition that is frequently missed until it reaches a critical stage.
* Early Arrhythmia Screening: The system identifies early signs of cardiac dysfunction and arrhythmias, enabling preventative care before emergency intervention is required.
2. Remote Cardiovascular Monitoring Platform
In addition to the point-of-care device, LightHearted AI provides a digital health platform for clinicians.
* Continuous Monitoring Algorithms: These algorithms analyze data from wearable sensors to provide long-term longitudinal insights into a patient's heart health.
* Expert-Level Accuracy: The platform delivers reports that match the accuracy of expert cardiologists, allowing primary care providers to make informed referral decisions without specialized cardiac training.
Impact on Global Healthcare
Cardiovascular disease is the leading cause of death globally, yet early detection remains elusive for many. LightHearted AI addresses several systemic challenges:
- Gender Bias in Diagnostics: Women with heart valve disease are seven times more likely to be misdiagnosed and die at double the rate of men. By removing human auditory bias and providing objective AI analysis, LightHearted AI aims to standardize outcomes across genders.
- Mass Screening Accessibility: Because the device is inexpensive and requires no specialized clinical skills to operate, it can be deployed for mass screenings in community pharmacies, rural clinics, and homes.
- Cost Reduction: By moving diagnostics into the primary care and home settings, the technology reduces the burden on expensive emergency departments and specialized cardiology wards.
Leadership and Strategic Backing
LightHearted AI is led by an interdisciplinary team with backgrounds in medicine, engineering, and quantum physics.
* Dr. Lucrezia Cester (CEO & Co-founder): A medical doctor and researcher who spearheaded the clinical application of laser-based diagnostics.
* Dilip Rajeswari (CTO & Co-founder): An engineer specializing in hardware-software integration for medical devices.
The company has received significant strategic support from major technology and venture capital entities, including Entrepreneur First, SOSV HAX, Intel Ignite, and Speedinvest. As of late 2025, LightHearted AI is pursuing Class IIa medical device approval to begin large-scale deployment within the UK?s NHS and international healthcare systems.
