A detailed injection, microradiographic, and histological necropsy study of 18 hearts showed that the pattern of myocardial veins differed from the arterial pattern. In "normal" hearts, large drainage veins began in the subendocardial zone and coursed fairly directly towards the epicardium, maintaining a comparatively even calibre throughout. Smaller, but similar, drainage veins also begain in the middle of the myocardial wall. In the outer myocardium small groups of these vessels converged to form a single vein which then entered, almost at right angles, the pericardial veins. In general, small veins within the myocardium entered directly into the large drainage veins without any extensive intermediate sized venous network. In "abnormal" hearts with left ventricular hypertrophy the myocardial veins appeared basically normal but were more widely separated and consequently overall less dense on microradiography. Interruption of main drainage veins and loss of normal pattern were seen in areas of myocardial fibrosis associated with coronary artery disease. In a heart with severe generalized coronary artery atheroma the normal pattern in the inner half of the wall was replaced by a "plexus" of small veins in which the majority of vessels coursed circumferentially. The possible significance of both the normal and abnormal vein pattern is discussed.
对18颗心脏进行的详细注射、微血管造影和组织学尸检研究表明，心肌静脉的模式与动脉模式不同。在“正常”心脏中，大的引流静脉始于心内膜下区域，相当直接地通向心外膜，全程保持相对均匀的管径。较小但类似的引流静脉也始于心肌壁中部。在外膜心肌中，这些血管的小群汇合形成一条单一静脉，然后几乎以直角进入心包静脉。一般来说，心肌内的小静脉直接进入大的引流静脉，没有任何广泛的中等大小静脉网络。在有左心室肥厚的“异常”心脏中，心肌静脉基本正常，但间隔更宽，因此在微血管造影上总体密度更低。在与冠状动脉疾病相关的心肌纤维化区域可见主要引流静脉中断和正常模式丧失。在一颗有严重广泛性冠状动脉粥样硬化的心脏中，壁内半部的正常模式被小静脉“丛”取代，其中大多数血管呈环行分布。文中讨论了正常和异常静脉模式的可能意义。
