DIAGnostic Research And Management

Your expert in cardiovascular research since 1996

We are a Contract Research Organisation (CRO) specialized in tailored cardiovascular research.

We’ve coordinated cardiovascular trials since 1996; we’ve performed over 246 trials across Europe and Asia. We’re rapidly becoming 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.

Our expertise

We have extensive expertise in all therapeutic areas of cardiology, with a special focus on intervention cardiology and electrophysiology.

On top of specialty expertise, our research professionals demonstrate an in-depth understanding of the complete care-chain (general practitioners, regional ambulance services, hospitals and cardiac rehabilitation).

Our standards

Clinical Trials in Cardiology

We conduct scientific research and registrations according to the appropriate guidelines: ICH-GCP, ISO 14155, FDA and/or Dutch law and regulations.

We’re also committed to quality: we comply with the ISO 9001 standard to ensure projects are consistent with client specifications, the relevant legislation and regulations. As a result, we’re NEN-EN-ISO 9001:2015 certified.

Our history

Twenty-five years ago, a group of pioneering interventional cardiologists (Prof. Felix Zijlstra, Prof. Menko Jan de Boer, Prof. Jan Hoorntje and Prof. Harry Suryapranata) based in the beautiful town of Zwolle, drastically improved the treatment of heart infarction. Their groundbreaking study, A comparison of immediate coronary angioplasty with intravenous streptokinase in acute myocardial infarction was published in the New England Journal of Medicine, 1993;328:680-684, and their treatment strategy became the new standard worldwide.

After their revolutionary study Diagram was founded, initially as a Site Management Organisation (SMO) to support clinical research locally and soon the CRO was added.

Since 1996, our organisation has continued to grow, performing an impressive 246 real-evidence trials across 25 countries and 173 hospitals.

Throughout all those years, cardiovascular research projects have always remained our focus. We’ve become an expert in coordinating and executing phase II-IV studies, working closely together with an excellent network of renowned cardiologists, sponsors and everybody along the care chain from emergency medical services to the hospital.
