For the DZHK Heart Bank, networking and cooperation with various stakeholders, such as researchers, employees at our DZHK Clinical Study Units, data and biosample donors as well as with organs such as biobanks, authorities, health care organizations and ethics experts, is very important, as all sides benefit from this, the scientific exchange is strengthened and comparative research is made possible. Often, specific competencies even complement each other, so that synergies arise, people support and exchange ideas and thus develop new ideas and drive them forward. A perfect basis for research and the resulting research projects.
