In August 2022, the European Society of Cardiology (ESC) published new guidelines on cardiovascular assessment and management of patients undergoing non-cardiac surgery. In order to cope with the complexity of the patients and the multidisciplinary, representatives of the European Society of Anesthesia and Intensive Care Medicine as well as 2 patient representatives were involved in the development of the published document in addition to authors from the European Society of Cardiology. As a result, the document contains 147 recommendations on this complex topic, with more than half of them being grade I recommendations.The interdisciplinarity and the need for interdisciplinary cooperation in this context is particularly emphasized. Particular attention was also paid to recommendations for action for a structured preoperative risk stratification. The new guidelines also focus on increasing vigilance for perioperative myocardial damage and identifying it at an early stage.In the following article, some of the essential innovations and revisions will be highlighted using practical clinical case studies., Competing Interests: Die Autorinnen/Autoren geben an, dass kein Interessenkonflikt besteht., (Thieme.

The new European Society of Cardiology (ESC) guidelines on the cardiovascular assessment and management of patients undergoing non-cardiac surgery were published in August 2022. In the preparation of the new document the previous guidelines published in 2014 were completely revised and the recommendations for action were adapted or renewed. Furthermore, the guidelines have been supplemented with some new chapters. The new and revised recommendations result in significant changes for the clinical practice. This particularly applies to the preoperative risk stratification, the perioperative risk management and the detection and management approaches in cases of perioperative and postoperative complications. Cardiovascular biomarkers play a special role in both the preoperative risk stratification and the detection of postoperative complications in combination with appropriate algorithms for action. The perioperative management of antithrombotic treatment (antiplatelet therapy or oral anticoagulation) is becoming increasingly individualized depending on the risk of ischemia or bleeding of the planned surgery. Particular attention is paid to the early detection of perioperative or postoperative myocardial infarctions based on determination of high-sensitivity (hs) cardiac troponin, not least because its association with high risk of morbidity and mortality. In patients with complex cardiovascular diseases, such as severe coronary artery disease, valvular heart diseases or those with ventricular support systems, the decision in an interdisciplinary team is highly recommended., (© 2022.

Objective: To determine whether there is a relationship between the circadian rhythm of acute myocardial infarction (AMI) in the morning hours and the sleep apnea syndrome (SAS)., Patients and Methods: 203 patients who had sustained an AMI were examined 7-14 days later for sleep-associated breathing disorders using a 5-channel recording system. The diagnostic criterion for SAS was > 10 episodes of apnea and hypopnea per hour (AHI >10). 76 % of all patients were male, mean age 62 years., Results: SAS was diagnosed in 91 of the 203 patients (44.8 %). Compared to the 112 patients without SAS there were significantly more AMI in the morning hours (6:00 am to 12:00 am) in the SAS-group (49.5 %) than in the non-SAS-group (21.4 %). The two groups differed with regard to the symptoms of day-time sleepiness (29.7 % vs 17.0 %), age (mean 64.6 years vs 60.2 years), gender (83.5 % vs 69.9 % male) and smoking (33.0 % vs 51.8 %). There were no significant differences in Body mass index, hypertension, hyperlipoproteinemia, diabetes mellitus, family history, history of cardiovascular disease and taking of sedatives., Conclusion: The strong association between SAS and morning onset of AMI found in this study could be the result of a sympathetic stress reaction to the breathing disorder.
