The clinical researchers involved in BigData@Heart have been instrumental in shaping current treatment and management of ACS, AF, and HF. They are joining forces with leading European epidemiologists, big data scientists, cardiovascular medical professionals, pharmaceutical industry scientists, and patient organization representatives. Thanks to this public-private partnership approach, BigData@Heart had access to most of the relevant large-scale European CVD databases, ranging from electronic health records and disease registries through well-phenotyped clinical trials, omics-data, and large epidemiological cohorts, together covering >5 million cases of AF, HF and ACS and >16 million healthy individuals. BigData@Heat used innovative statistical, machine learning, and data-mining methodologies.
