Mean arterial pressure = {(Systolic blood pressure − Diastolic blood pressure)/3} + Diastolic blood pressure. Cardiac output monitoring in the critically ill patient is standard practice in order to ensure tissue oxygenation [] and has been traditionally accomplished using the pulmonary artery catheter (PAC).In recent years, however, the value of PAC has been questioned with some suggesting that its use might not only be unnecessary but also potentially harmful []. https://orcid.org/0000-0002-6569-1805. Cardiogenic shock (CS) remains the leading cause of death in patients hospitalized with acute myocardial infarction (AMI), occurring in 5% to 15% of cases (1–5). Most studies suggest that early coronary revascularization improves survival (6–9), and achievement of artery patency in the infarct-related artery is crucial in this situation (8).
