摘要: 为探讨静脉点滴硝酸甘油(NTG)介入99mTc-甲氧基异丁基异腈(MIBI)心肌断层显像在心肌存活估测中的价值,对57例心肌梗塞病人进行99mTc-MIBI静态心肌显像及静脉点滴NTG后显像。静态心肌显像有207/513(40.4%)的节段灌注异常,NTG滴注后有75/207(36.2%)的静态灌注异常节段得到改善。表明NTG静脉介入能提高静态99mTc-MIBI对存活心肌的检测率.

Abstract: To compare the clinical effect rest 99mTc-MIBI myocardial tomography with that folling intravenous infusion of nitroglycerin(NTG)in assessing myocardial viability. Rest99mTc-MIBI myocardial tomograthy imagings were performed in 57 patients with myocardial infarction. There were 207(40.4%, of 513)segments of hypoperfusion in the rest imagings of the 57 patients. The improvements of perfusion after NTG infusions were revealed to be in 75(36.2%)of the 207 segments. Combination of rest 99mTc-MIBI myocardial tomography imaging with intravenous NTG infusion could efficiently detect the residual survival myocardium in the patient with myocardial infarction.
