About

Dimitri Petsikas is a clinician-researcher whose work sits at the critical intersection of cardiac surgery and neurology. His primary research focus is understanding and quantifying the neurological dysfunction that frequently occurs after coronary artery bypass grafting (CABG). Rather than relying on subjective assessments, Petsikas has pioneered the use of quantified, pre-operative neurological testing to predict patient outcomes, a significant methodological contribution that brings much-needed rigor to the field. His most cited work, "Quantified pre-operative neurological dysfunction predicts outcome after coronary artery bypass surgery" (2019, 9 citations), establishes a framework for identifying at-risk patients before they enter the operating room. Petsikas has also been a leading voice in investigating the role of regional cerebral oxygen saturation (rSO₂) as a potential mechanism for postoperative impairment, as detailed in his protocol study "Road to recovery" (2019, 4 citations) and his feasibility study on the relationship between cerebral oxygen levels and neurological metrics (2018, 2 citations). By championing quantitative, objective measures over vague clinical impressions, Petsikas is helping to build a more predictive and preventative science of perioperative brain health.
