心臟血管專科：如何評估冠狀動脈疾病風險？-心臟血管專科

可以請醫師看看嚴重性嗎？

Risk Factors:H/T(-); DM(-); Hyperlipidemia(+); Smoking(-); Family History(+);PROCEDURES:1. Gated myocardial perfusion scan was performed with intravenous infusion of 3 mCi of thallium-201 at stress. Resting gated myocardial perfusion scan was obtained 2 hours after injection.2. Stress was undertaken by vasodilator-stress with intravenous infusion of 0.56 mg/kg of persantin (total dose: 28 mg).3. Aminophylline (125 mg) were given for relief of discomfort.4. BP(basal->peak): 119/83 -> 112/81 ; HR: 72 -> 90FINDINGS:1. There is reversible perfusion abnormality in the apical-mid-basal anterior, and mid-basal anteroseptal segments.2. Wall motion study for poststress: hypokinesis in the basal anteroseptal segment; rest: normokinesis3. The estimate LVEF was: post-stress= 78%, rest= 79%.4. There is no stress-induced LV dilation and no abnormal lung uptake.CONCLUSION:1. The perfusion images suggest myocardial ischemia in the apical-mid-basal anterior, and mid-basal anteroseptal segments.2. The functional analysis revealed normal LV systolic function with regional wall motion abnormality.3. CAD involving the territory of LAD is suspected.4. The risk for cardiac event is intermediate.
