The document titled "Second Edition of the German-Austrian S3 Guideline 'Infarction-Related Cardiogenic Shock: Diagnosis, Monitoring and Treatment'" provides recommendations for the diagnosis, monitoring, and treatment of infarction-related cardiogenic shock (ICS). The guideline was developed by German and Austrian medical societies and includes 95 recommendations and 7 algorithms. It emphasizes the importance of monitoring blood pressure, cardiac output, and oxygen balance to guide hemodynamic therapy. The document also discusses the timing and type of revascularization for patients with acute myocardial infarction (MI) complicated by cardiogenic shock. It recommends prompt intervention with primary percutaneous coronary intervention (PCI) within 90 minutes of first medical contact and suggests that PCI with a drug-eluting stent is the reperfusion technique of choice for most patients. The text also discusses the use of mechanical circulatory support (MCS) devices as an alternative treatment for severe, refractory cardiogenic shock. The choice of MCS device depends on various factors, including the type of shock and available resources. The document also covers aspects of critical care medicine for patients with ICS, including invasive ventilation, management of acute kidney injury, transfusion strategies, nutrition, and glucose control. The recommendations provided aim to improve patient outcomes based on available evidence. [Extracted from the article]
