World Heart Day 2025: Meet The Startups Revolutionising Cardiac Care

According to the World Heart Federation, up to 80% of premature cardiovascular disease (CVD) deaths are preventable.

Through a mix of access to care, early screening, nutrition and exercise, more people can live their lives with truly healthy hearts.

That’s why today, on World Heart Day, the world comes together to raise awareness, inspire action and celebrate heart health. Over 20 years ago, the World Health Organisation (WHO) established World Heart Day to inspire international action against cardiovascular diseases.

 

How Is Tech Helping People Improve Heart Health?

 

Cardiovascular diseases are one of the leading causes of death around the world, taking an estimated 17.9 million lives every year (WHO).

In the UK CVD accounts for around a quarter of all deaths according to the British Heart Foundation – making it a huge problem to resolve.

However, up to 80% of premature deaths are preventable. And with so many tech devices available to help, CVD prevention is certainly becoming more accessible.

Here are some of the ways that tech is helping:

Wearables: A lot of early detection comes from monitoring heart health, and wearables are making this much easier! Wearables can continuously monitor heart rate, identify any irregularities and even monitor blood-oxygen levels. By having a consistent dataset to draw from, wearables make early detection much easier.

Lifestyle tracking: Many apps exist to help people track their nutritional health and exercise, allowing them to make lifestyle changes that are good for their heart. Combine that with personalised tracking and recommendations, and the impact is invaluable.

AI diagnoses: AI is becoming more commonly used in medicine, especially as a way to find and diagnose irregularities. Many companies now use AI to analyse data and find signs of heart health that humans might miss. This allows doctors to find issues earlier and provide better treatments.

 

 

Who Are The Startups Improving Heart Health?

 

In honour of World Heart Day, we have pulled together a list of startups that are changing the way people monitor and care for their hearts.

These include:

 

Acorai

 

 

Acorai has developed an AI-powered, non invasive heart monitoring device, allowing people to constantly measure their heart health in real-time.

Through the device, users can track pulmonary and cardiac pressures, which are believed to be the earliest signs of heart failure. Through early, non-invasive detection, Acorai can help people gain a fuller picture of their heart heath before it’s too late.

 

Kardi AI

 

 

Kardi AI provides a device to help people monitor their heart health on a daily basis. The device not only identifies any cardiac arrhythmias, but can also give users insight into how their lifestyle choices are affecting their hearts.

That way, they can have a full picture of their heart data, allowing them to access personalised care before symptoms get worse.

 

Cardio AI

 

 

Cardio AI helps cardiologists more accurately interpret electrocardiograms. Through this, doctors are able to improve the accuracy and early detection of any cardiovascular diseases.

The system works by cross-analysing images, genetic information and ECGs to help with diagnosis, risk assessment and treatment planning. This not only improves care, but allows doctors see things they may have otherwise missed.

 

 

Eko

 

 

Eko has created a digital stethoscope that is embedded with an AI diagnostics tool, designed to help pick up on any irregularities.

With data analysis that extends to both the heart and the lungs, Eko allows anyone to monitor their heart health wherever they are. And it works, with the company reporting that providers who use Eko are 2x more likely to detect heart diseases than those that don’t.

 

Prometheus

 

 

Prometheus is on a mission to improve early detection of congenital heart defects. Through their AI algorithm, they are able to detect congenital heart defects in ultrasound recordings during routine pregnancy screenings.

Their AI analyses 2D foetal heart clips to identify any red flags between the 17th and 28th week of pregnancy.

 

Cardiawave

 

 

Cardiawave has developed a non-invasive ultrasound therapy to treat calcific aortic stenosis. Aortic stenosis happens when the aortic valve narrows, making it harder for blood to exit the heart and head towards the vital organs.

In developed countries, AS is the third-most frequent cardiovascular disease, making it an important problem to resolve.

Through their ultrasound therapy, cardiawave is able to open up the valve, allowing for better blood flow and heart health.

 

Heartflow

 

 

Heartflow uses AI to create a 3D model of a patient’s heart, making it easier for doctors to understand the right treatment for them.

As conventional diagnostic methods can be prone to error, Heartflow is on a mission to make treatment more personalised and more accurate for each patient.
