title: [Mechanisms of the development of hemorrhagic myocardial infarction and the criteria of angiographic diagnosis].
abstract: Unlike ischemic myocardial infarction, hemorrhagic myocardial infarction develops with active involvement of vessels of microcirculation and veins which are implicated in the process concurrently with great coronary artery occlusion or immediately after blood flow normalization. Morphological changes found in the vessels of microcirculation and veins suggest that the majority of them have advanced spasm. This leads to abnormal blood outflow from the hemorrhagic myocardial infarction zone, which is followed by extensive blood interstitial saturation with continuous blood inflow (ante- and retrogradely). Angiography reveals hypervascularization in the area of evolving infarction (a late arterial period), intensive contrast (a parenchymatous period), contrast agent extravasation and its prolonged elimination from the distal channel (a venous period).
