A histometric and histochemical study of myocardial ventricular capillaries was carried out in cases of sudden coronary death (SCD) in the absence of myocardial infarction and postinfarction cardiosclerosis. Heterogenic pattern of capillary blood filling, increased quantity of plasmatic capillaries, their reduced density per unit of area and sparser distribution, as well as greater metabolite ultrafiltration diameter were demonstrated, as evidence of disturbed myocardial transcapillary metabolism. Decreased muscular fiber/capillary rations, "vesicles" emerging in the capillary lumen and sludging in some vessels determine impairment of capillary perfusion. Two groups of cases were identified: those with uniform blood overfilling of capillaries and with uniform compression of the capillary lumen that must be due to the fact that death occurred during the systolic or diastolic phase, respectively.
对无心肌梗死及心肌梗死后心脏硬化的心脏性猝死（SCD）病例进行了心肌心室毛细血管的组织计量学和组织化学研究。结果显示毛细血管血液充盈呈异质性模式，血浆毛细血管数量增加，单位面积密度降低且分布稀疏，以及代谢物超滤直径增大，这些均表明心肌跨毛细血管代谢紊乱。肌纤维/毛细血管比率降低、毛细血管腔内出现“囊泡”以及部分血管内血流淤滞，均表明毛细血管灌注受损。确定了两组病例：一组是毛细血管血液均匀过度充盈，另一组是毛细血管腔均匀受压，这必定分别是由于死亡发生在收缩期或舒张期。
