[Out-of-hospital sudden coronary death: separate acute coronary syndrome or the mode of death due to ischemic (coronary) heart disease?].

Background: The existing data on the morphological substrate of out-of-hospital sudden death due to ischemic (coronary) heart disease (IHD) and its relationship to other acute coronary syndromes are not sufficient and even controversial.

Material And Methods: We analyzed clinical and pathological data from 170 men who died suddenly (within 6 h) of IHD out of hospital, as well as 54 men who died in hospital a documented acute myocardial infarction (AMI).

Results And Conclusions: Majority (92,9%) of out-of-hospital sudden coronary deaths were due to AMI and 7,1%t - due to disseminated myocardial micronecroses.

[Characteristics of compensatory myocardial hypertrophy in ischemic heart disease].

A 30% increase in mean values of net weight of the heart and the weight of its individual portions in 88 males, who had suffered from coronary disease and died suddenly as a result of the first major coronary disaster (in the absence of postinfarction scars and systemic arterial hypertension) was indicative of an evenly distributed compensatory myocardial hypertrophy of the entire heart. Therefore, detection of increased heart weight may be used as an additional indicator for intravital and postmortem diagnosis of early and latent coronary heart disease.

[Changes in the cardiometric parameters in ischemic heart disease].

Study of planimetric and weight indices of individual parts of the heart in 55 males (average age 51.2 +/- 2.7 years) who died of the first or repeated (primarily early) myocardial infarction has revealed the appearance (prior to the first major coronary event) of compensatory myocardial hypertrophy of all parts of the heart.

[Technical potentials for performing intravital aortocoronary shunting in sudden death from ischemic heart disease (based on postmortem coronary angiographic data)].

Technical feasibility of aortocoronary shunting was examined retrospectively in 70 cases where sudden coronary death had occurred outside of hospital. Postmortem coronary angiograms, coronary arterial cross sections made at 5 mm intervals, and the nature and spread of focal myocardial lesions were studied. A coronary artery with more than 50% of its lumen affected in the proximal or middle part, but no significant narrowings in the distal channel, was considered shuntable if myocardial focal lesions did not exceed 15% of left-ventricular and interventricular-septum volume.

[Sudden death outside the hospital from coronary heart disease: the state of the intercoronary artery collaterals].

By means of postmortem selective coronary angiography coronary collaterals of 55 sudden out-of-hospital coronary death victims were investigated. The collaterals were found in most (58,5%) sudden coronary death cases. There was no correlation between the presence of coronary collaterals, on the one hand, and ischaemic heart disease symptoms during the life and focal myocardial lesions in deceased persons, on the other.
