Our take
HeartFlow was founded in 2007 and is a medical equipment manufacturer that uses CT-scanned 3D modelling to assess and analyze a patient's arteries. This noninvasive process can help assess the risks of heart disease and strategize the appropriate treatment.
HeartFlow has had a long history of awards and innovations. In 2021, it brought its technology to the NHS in England and in October 2022, introduced a plaque analysis service. As time has gone on, Heartflow has indicated that it is keeping up with technological advances and finding new ways to provide heart health services through them.
HeartFlow successfully launched its IPO in 2021 but faced a setback when its merger with Longview Acquisitions was called off in 2022 due to unfavourable market conditions. Despite this, the company has made a strong comeback and recently unveiled its next-generation plaque analysis AI, demonstrating its continued commitment to innovation and growth.
