Purpose of the study: Cardiogenic shock is a frequent and severe complication of cardiovascular events and is associated with high in-hospital mortality rates. Parameters of initial blood gas testing in the catheterization laboratory can be useful prognosticators. Lactate is already a validated parameter for early prognostic assessment of patients with cardiogenic shock. Early blood glucose, however, requires further exploration as a predictor of cardiogenic shock outcomes. Methods: Data were collected within the single centre PREPARE CardShock Registry that includes patients who presented with cardiogenic shock and underwent cardiac catheterisation at University Heart Centre Graz. 664 patients were recruited between 01.04.2019 and 31.03.2024. For the analysis, patients were divided into three pre-defined groups based on their initial blood glucose levels. Results: Higher initial blood glucose levels were significantly associated with higher in-hospital mortality and longer hospital and coronary care unit stays. Additionally, an increased need for norepinephrine and more frequent use of resuscitation and mechanical assist devices were observed. Patients in higher glucose groups also required more time on respirators. Conclusion: The findings indicate a worse outcome and prognosis for patients with elevated initial blood glucose levels compared to those with lower blood glucose levels, suggesting that this value can be a useful predictor of cardiogenic shock outcomes.
