Research interests

Organ protection and outcome in cardiac surgery patients

Since our first, important and very often cited publication in the year 2000 our group researches increasingly on organ protection and non-surgery-related risk profiles.

Main research interest is now on cohort studies in order to find valuable predictors, models and risk indicators for several, especially renal, organ protection and dysfunction. In this context, research about risk and prevention of acute kidney injury (AKI) in cardiac surgical patients remains the most important topic.

Ongoing projects include investigations on

  • Short-term changes (within 120 min) in serum creatinine (SCrea) levels after cardiac surgery and prediction on outcome (30-day mortality).
  • The involvement of known risk indicators on short- and long-term mortality (EuroSCORE)
  • Urinary neprilysin

Techniques, methods & infrastructure

Coordination with the Institute of Medical Statistics and the Clinical Institute of Infection Control and Hospital Epidemiology, Medical University of Vienna, with other European Centers in a European Workgroup of Cardiothoracic Intensive Care as important Human Resources. Technically/statistically we perform survival analyses which have been received considerable attention and can be found in many different fields of medicine.
