Clinical manifestations of coronary disease, medical history, left-ventricular segmental contractility and central hemodynamics were examined in 54 patients, aged 32 to 45, with an isolated 75-99% stenosis of a major coronary artery. The most common isolated stenosis in the anterior interventricular branch (AIVB) of the left coronary artery is associated with more severe clinical coronary symptoms. Total damage to the coronary channel is twice as great where AIVB is affected as it is with lesions of the right (RCA) or the circumflex (CA) coronary artery. AIVB stenosis results in more serious disorders of left-ventricular segmental contractility and central hemodynamics, with the end diastolic index showing the most dramatic rise. Isolated AIVB stenosis is associated with a higher risk of myocardial infarction, as compared to the RCA or CA stenosis.
对54例年龄在32至45岁之间、主要冠状动脉孤立性狭窄75%至99%的患者进行了冠心病临床表现、病史、左心室节段性收缩功能和中心血流动力学检查。左冠状动脉前室间支（AIVB）最常见的孤立性狭窄与更严重的临床冠状动脉症状相关。当AIVB受累时，冠状动脉通道的总损伤是右冠状动脉（RCA）或左旋支冠状动脉（CA）病变时的两倍。AIVB狭窄导致左心室节段性收缩功能和中心血流动力学更严重紊乱，舒张末期指数升高最为显著。与RCA或CA狭窄相比，孤立性AIVB狭窄与更高的心肌梗死风险相关。
