This philosophy led to the foundation of x-cardiac.

The x-cardiac story

In 2014, while working as a resident cardiac surgeon, Alexander Meyer came into contact with a clinical problem that had been unsolved until then. This problem was to identify at an early stage which patients were at high risk of major complications after cardiac surgery. Being a computer scientist as well, Alexander Meyer saw a great opportunity to take software analysis methods and artificial intelligence techniques to actually provide him and his team of intensive care physician with a lot better information about patients at risk of complications. This basic concept aims to dramatically improve the diagnosis of complications after heart surgery, which is the foundation of x-cardiac.

After building an initial proof of concept, the x-cardiac team formed during several public grants, such as the BIH Digital Health Accelerator, the Clinician Scientist Program at Charité Berlin and the Spark Validation Fund. In late 2020, after years of hard work, the founding team of Oliver Höppner, Alexander Meyer and Kay Brosien launched the company x-cardiac GmbH.

The great innovation of x-cardiac is to extract already existing data from the hospital database and add a layer of clinically meaningful information in form of predictions. 


With x-cardiac, we want to be the orchestrator of change and drive the field of digital health, because it is changing the way we care for our patients. This is what we live for.
