[The AHA/ACC/ASE/CHEST/SAEM/SCCT/SCMR guidelines 2021 on thoracic pain].

The AHA/ACC/ASE/CHEST/SAEM/SCCT/SCMR guidelines 2021 on thoracic pain focusses on chest pain as a single but important symptom. The guidelines fall back on many guidelines on cardiac disease entities, such as myocardial infarction with (STEMI) or without ST segment elevation (NSTEMI), chronic coronary artery disease (CAD), pericarditis and aortic dissection. They also refer to guidelines on cardiac syndromes, such as acute coronary syndrome (ACS) or ACS without persisting ST segment elevation (NSTE-ACS), in which angina pectoris is an integral component. The guideline separates acute from stable angina pectoris. It gives a comprehensive overview on risk stratification and clinical work-up of chest pain. It stretches the main theme to angina equivalents, such as dyspnoe. They meticulously weigh up the noninvasive against the invasive diagnostic methods under the aspects of a cost-benefit analysis. In this context, a clear trend towards evidence-based, cost-effective noninvasive methods in recent years is unmistakable.
