The flagship P4-medicine project DigiMed Bayern was launched at the end of 2018 with more than € 20 million funding by the Bavarian State Ministry of Health and Care. DigiMed Bayern combines comprehensive datasets of patients diagnosed with atherosclerotic diseases, such as coronary heart disease and stroke, or with genetic risk factors. This dataset will be further enriched with state-of-the-art multi-dimensional molecular characterization (-omics technologies) of associated sample material. For the integrative analysis of the resulting "Big Data", an ethically and legally compliant, highly secure and sustainable IT infrastructure will be fundamentally designed and implemented. Finally, patients and persons at risk will benefit from advancements in disease risk prediction, targeted prevention, diagnosis and treatment.
