Preoperative Anemia and Transfusion in Cardiac Surgery: A Single-Centre Retrospective Study
Preoperative anemia is present in 15% of patients at our centre and these patients have 53% transfusion rates on surgery day. Hemoglobin concentration, eGFR, BSA, and total cardiopulmonary bypass time were predictors of transfusion on surgery day. Patients had a median of 7 days between initial visit and surgery day. Referral and anemia treatment were infrequently initiated in preoperative anemic patient.

Calcium Sensitisation Impairs Diastolic Relaxation in Post-Ischaemic Myocardium: Implications for the Use of Ca(2+) Sensitising Inotropes after Cardiac Surgery
We hypothesised that Ca(2+) sensitisation exacerbates post-ischaemic myocardial stunning by impairing diastolic relaxation, which might have deleterious effects in postoperative cardiac surgical patients.
