心肌灌注檢查結果解析-心臟血管專科

確認心肌灌注檢查結果？

吳主任您好,家母這幾天因胸痛做了心肌灌注檢查，出來報告結果如下：但回診時間還有兩個禮拜時間，現在想詢問心臟方面有哪些問題？
感謝Clinical Impression: Suspected crescendo angina; Hypertension; Hyperlipidemia Scintigraphic Findings and Impression: The patient completed the stress test on the standardized dipyridamole protocol (0.56 mg/kg IV infusion over 4 minutes). Clinically, the patient had no chest discomfort during the stress test. Electrocardiographically, there were no ischemic ST-T changes during the examination. The patient was injected with 0.82 mCi of thallium-201 3 minutes following the end of dipyridamole infusion. Images of the myocardium were obtained in 180-degree tomographic acquisition and the images were reconstructed in the short axis, vertical long axis and horizontal long axis. The images revealed evidence of (1) a mild, medium to large-sized, fixed perfusion defect in the apex, (2) a mild, small to medium-sized, fixed perfusion defect in the anterior/anteroseptal and anterior walls (apical level), (3) a mild, small to medium-sized, fixed perfusion defect with reverse redistribution in the lateral wall (apical level), and (4) stress-induced left ventricle (LV) dilation. The L/H (lung/heart) ratio = 0.31. IMPRESSION: Abnormal dipyridamole stress Tl-201 SPECT myocardial perfusion imaging with (1) a mild, medium to large-sized, fixed perfusion defect in the apex, (2) a mild, small to medium-sized, fixed perfusion defect in the anterior/anteroseptal and anterior walls (apical level), (3) a mild, small to medium-sized, fixed perfusion defect with reverse redistribution in the lateral wall (apical level), and (4) stress-induced LV dilation. Clinical correlation is necessary and coronary angiography may be indicated.
