本院观察了冠脉正常和冠脉病变者造影前后的心率(HR),左室收缩压(LVSP)、左室舒张最低压(LVDP)、左室舒张末压(LVEDP)的变化,探讨造影剂对左室功能的影响。对象与方法60例均行左室电影造影和选择性冠脉造影。冠脉正常者30例,有病变者30例(陈旧心梗15例,心绞痛15例)。冠脉病变标准为至少有一主支冠脉内径狭窄≥50%。造影剂为76%的泛影葡胺,
In our hospital, we observed changes of heart rate (HR), left ventricular systolic pressure (LVSP), left ventricular diastolic pressure (LVDP) and left ventricular end-diastolic pressure (LVEDP) before and after angiography in patients with coronary artery disease and coronary artery disease Effect of agents on left ventricular function. Subjects and methods All 60 cases underwent left ventricular angiography and selective coronary angiography. 30 cases of normal coronary artery, 30 cases of lesions (15 cases of old myocardial infarction, angina 15 cases). Coronary disease criteria for at least one of the main branch coronary stenosis diameter ≥ 50%. Contrast agent 76% of the diatrizoate,
