The paper discusses the problems in the formation of statistical information on acute forms of coronary heart disease (IHD) in Russia and possible ways of their solution. Among other problems, there is the detection and notification of cases of sudden coronary death as an independent nosological entity that belongs to the acute forms of IHD. The terminology and classification of the acute forms of IHD, which affect the formation of statistical data, are considered. The consequences of underestimates of the role of a postmortem study, as the most important postmortem diagnostic method, in modern practical health care are discussed. The paper is largely debatable and intended for a wide circle of readers in order to attract their attention to the detection and notification of the acute forms of IHD in clinical practice, especially in cases of death from acute IHD in the prehospital stage.
