本文报告了用门电路心血池显象法研究心肌梗塞病例,了解何种情况出现右心功能低下。对象及方法:正常者10例,住院经冠状动脉造影证实为缺血性心脏病者35例。正常者为1组,缺血性心脏病分为4组(2～5组)。2组为陈旧性心肌梗塞,狭窄在冠状动脉的近位端(10例);3组亦为陈旧性心肌梗塞,狭窄在冠状动脉的远位端(7例);4组为陈旧性前壁梗塞,无右冠状动脉狭窄(12例);5组为右冠状动脉近位端狭窄,但未并发心肌梗塞(6例)。全部病例均于两周内进行了门电路心血池显象及心导管检查。
This article reports a case study of myocardial infarction with a portal circuit cardiopulmonary imaging method to see what happens when the right heart is impaired. Subjects and Methods: Normal 10 cases, hospitalized by coronary angiography confirmed ischemic heart disease in 35 cases. Normal group 1, ischemic heart disease is divided into 4 groups (2 to 5 groups). Group 2 was an old myocardial infarction with stenosis at the proximal end of the coronary artery (n = 10); group 3 was also an old myocardial infarction with stenosis at the distal end of the coronary artery (n = 7); group 4 was an old anterior wall Infarction, right coronary artery stenosis (n = 12); group 5 was proximal stenosis of right coronary artery, but no myocardial infarction (n = 6). All cases were carried out within two weeks of portal blood pool imaging and cardiac catheterization.
