冠状动脉粥样硬化性心脏病(简称冠心病)是一种常见病,但本病在临床诊断上比较困难。除典型的心绞痛或心肌梗塞外,有些病人虽冠状动脉硬化巳很广泛,但临床上仍可能没有症状,直到一支主要的冠状动脉管径的横断面减少75%以上,才产生心肌缺血的征象。而且冠心病人常合并高血压,而高血压病亦易并发冠心病。早期诊断并鉴别二病在指导治疗及预防并发症上有很大意义。超声心动图是较敏感而又无损伤性检查法,在诊断上有一定参考意义。
Coronary atherosclerotic heart disease (referred to as coronary heart disease) is a common disease, but the disease is more difficult in clinical diagnosis. In addition to the typical angina pectoris or myocardial infarction, although some patients have a wide range of coronary arteriosclerosis, but may still clinically no symptoms, until a major coronary artery diameter cross-sectional reduction of more than 75%, had a myocardial ischemia Signs. And coronary heart disease often complicated by hypertension, hypertension is also complicated by coronary heart disease. Early diagnosis and identification of two diseases in guiding the treatment and prevention of complications have great significance. Echocardiography is more sensitive and non-invasive examination method, there is a certain reference value in the diagnosis.
