This article, published in the journal Thoracic & Cardiovascular Surgeon, explores the relationship between calcium-induced left atrial and right atrial contractile forces and kinetics, preoperative patient state, and postoperative atrial fibrillation (POAF) after elective on pump cardiac surgery. The study evaluated 119 patients who had preoperative sinus rhythm, with 54 patients developing POAF postoperatively. The results showed altered contractile and kinetic conduct of cardiac myofilaments and intact muscle cells in POAF patients before the clinical appearance after cardiac surgery. The authors suggest that detecting these patients preoperatively could potentially change the prophylaxis, treatment, and outcome of POAF patients. [Extracted from the article]

This article, titled "Cerebral Near-Infrared Spectroscopy Monitoring as a Predictor for Postoperative Inadequate Emergence Following Anesthesia in Adult Cardiac Surgery Patients: Myth or Reality?", explores the association between cerebral oxygen saturation decrease and inadequate emergence after cardiac surgery. The study included 309 patients over the age of 50 who underwent elective cardiac surgery. The results showed that patients with inadequate emergence had a longer duration of cerebral oxygen saturation reduction and ventilation. However, further research is needed to confirm these findings in a larger sample size. [Extracted from the article]
