Methodological issues of the importance of diagnostic criteria for chronic ischemic heart disease for morbidity and mortality statistics

There are disagreements between various professional medical communities and schools of thought regarding certain concepts, terms, and diagnostic criteria for certain nosological forms of certain diseases. An example is the nosological entities included in the group of chronic coronary artery disease (CAD), which is explained by rapid changes in the understanding of coronary insufficiency pathogenesis, as well as a common morphological substrate characteristic of various clinical variants of chronic CAD. This paper summarizes and describes key unresolved issues in the clinical, morphological, and statistical criteria for diagnosing nosological entities within the chronic CAD group, which may influence the related morbidity and mortality statistics in the Russian Federation.
