Also, after the number of infections had declined, intensive care beds were kept free prophylactically; however, the percentage of beds reserved for COVID-19 differ in the individual federal states in Germany. The aim of this article is to define a necessary clearance quota of intensive beds for COVID-19 patients in Germany. An escalation and de-escalation scheme was created for rising and falling numbers of infected patients.</p><p><strong>Methods: </strong>Data from the COVID-19 resource board of the state of Baden-Württemberg, the daily situation report of the Robert Koch Institute (RKI), the register of COVID-19 intensive care beds of the German Interdisciplinary Association for Intensive Care and Emergency Medicine (DIVI) as well as the daily report of COVID-19 Baden-Württemberg from April to November 2020 were used for the calculation.</p><p><strong>Results: </strong>At the end of November 2020 approximately 13.5% of intensive care beds in Germany were used by COVID-19 patients.

Many patients suffer from major adverse cardiovascular events, e.g. myocardial infarction, which in the long term can result in severe limitations in routine activities. Troponin plays the central role in identifying myocardial infarction; however, interpretation after cardiac surgery is difficult due to ischemia reperfusion injury and direct surgical trauma. Thus, the distinction between procedure-related myocardial injury and additional myocardial injury due to a new event is difficult. The fourth universal definition of type 5 myocardial infarction uses the 10 × upper limit of normal (ULN) as cut-off and notably > 90% of patients after on-pump procedures exceed this cut-off. Clinical consequences are mostly unclear. The dynamics of copeptin and heart-type fatty acid binding protein (H-FABP) concentrations start very early, i.e. several hours before troponin. The characteristics of copeptin and H‑FABP might help to overcome the limitations of troponin. This short narrative review gives a concise overview on this topic.
