近年一些研究表明,某些原因不明的心脏疾患如不明原因的心脏扩大、原发性肺动脉高压、心肌病、冠状动脉正常的缺血性心脏病、不明原因的猝死及某些全身性血管疾病的心脏病变等似均与小冠状动脉病变有关,因而小冠状动脉疾病渐受重视。本文简要介绍小冠状动脉的解剖概念,及小冠状动脉疾病的病因、病理和临床。小冠状动脉的解剖概念小冠状动脉系指管径0.1～1.0mm的冠状动脉远端分支。它与“壁内动脉”或“心肌内动脉”的概念尚不尽相同,小冠状动脉不一定都分布于心肌壁内,同时大冠状动脉亦有一
In recent years, some studies have shown that certain unexplained heart diseases such as unexplained heart enlargement, primary pulmonary hypertension, cardiomyopathy, normal coronary heart disease, sudden death of unknown cause and some systemic vascular diseases Heart lesions and other similar small coronary artery disease, and therefore less attention to small coronary artery disease. This article briefly introduces the anatomy of small coronary arteries, and the etiology, pathology and clinical features of small coronary arteries. Anatomical concept of small coronary arteries Small coronary arteries refer to distal coronary arteries with a diameter of 0.1 to 1.0 mm. It and the “intra-arterial” or “intra-myocardial artery” concept is not the same, small coronary arteries are not necessarily distributed in the myocardial wall, while the large coronary artery also has a
