To evaluate function of the left ventricle and myocardial perfusion images, digital subtraction angiography (DSA) was performed in 45 patients with ischemic heart disease. Validity of the technique was compared with data obtained from cine left ventriculogram in all patients and 201 T1 myocardial images in 20 patients. End-diastolic volume (EDV), end-systolic volume (ESV) and ejection fraction (EF) calculated from DSA were correlated closely with those from cine left ventriculogram (r = 0.92, r = 0.94 and r = 0.86, respectively). Regional contractility at the antero-lateral wall of the left ventricle, assessed by DSA, was also correlated well with cine left ventriculogram (r = 0.75). Evaluation of the inferior wall motion showed less correlation in both procedures (r = 0.68). Phase and amplitude analysis with the same technique with radionuclide cardiac angiography was successfully applied in left ventriculogram obtained by DSA. The procedure seems to be helpful for objective evaluation of the left ventricular wall motion. Myocardial perfusion image, obtained with modified Radtke's technique, showed good coincidence with 201 T1 images. Thus, DSA is applicable for evaluation of function of the left ventricle and myocardial perfusion in patients with ischemic heart disease.
为评估左心室功能和心肌灌注图像，对45例缺血性心脏病患者进行了数字减影血管造影（DSA）。将该技术的有效性与所有患者的电影左心室造影数据以及20例患者的201Tl心肌图像数据进行了比较。通过DSA计算的舒张末期容积（EDV）、收缩末期容积（ESV）和射血分数（EF）与电影左心室造影计算的结果密切相关（分别为r = 0.92、r = 0.94和r = 0.86）。通过DSA评估的左心室前侧壁区域收缩性也与电影左心室造影相关性良好（r = 0.75）。两种方法对下壁运动的评估相关性较低（r = 0.68）。用相同技术对放射性核素心血管造影进行的相位和振幅分析成功应用于通过DSA获得的左心室造影。该方法似乎有助于客观评估左心室壁运动。用改良的拉德克技术获得的心肌灌注图像与201Tl图像显示出良好的一致性。因此，DSA适用于评估缺血性心脏病患者的左心室功能和心肌灌注。
