Coronary heart disease (CHD) is the leading cause of death in Germany. There are no recent studies on temporal trends in mortality due to chronic CHD. The aim of the present analysis was therefore to examine changes in long-term trends in CHD mortality between 1998 and 2023. The focus is on sex- and age-specific developments and further distinguished between ICD-10 subgroups for acute myocardial infarction (AMI) and (non-AMI-related) chronic CHD.
