About Diagram
We're a Contract Research Organisation (CRO) specialised in tailored cardiovascular research.
We’ve coordinated clinical trials and studies since 1996; we’ve performed over 250 trials across Europe and Asia and we're an expert in pre-hospital phase studies and e-health projects.
We focus on:
- Investigator Initiated studies, using cost-effective models without compromising quality; - Industry-driven studies; trials driven by the pharmaceutical, medical devices and e-Health industries.
Our groundbreaking research is often presented at the main cardiology conferences, including ESC, EuroPCR, EHRA, TCT and ACC and published in leading medical publications.
We’re the proud partner and coordinator of the EU-CaRE project, an e-health project that received funding from the European Union’s Horizon 2020 research and innovation programme under grant agreement No 634439.
Need support for your cardiovascular trial? You've come to the right place!
