The 2019 guidelines of the European Society of Cardiology (ESC) rename stable coronary heart disease to chronic coronary syndrome (CCS). Under CCS, six different scenarios have been defined, which take its heterogeneity into account. An important part of the current guideline plays the diagnostic assessment of the pre-test probability in the event of the possible presence of stenosing coronary heart disease. The addition of dyspnea and clinical probability as additional variables for better estimation of the pre-test probability are two important new features. Imaging techniques such as CT angiography have been significantly upgraded as diagnostic procedures for the detection of CHD, while exercise ECG is no longer routinely recommended in this regard. Invasive coronary angiography with revascularization option remains a central diagnostic and therapeutic procedure. In addition to antianginal, lipid-lowering and antithrombotic therapy, the current CCS guideline places special emphasis on prevention by means of lifestyle modification.
