摘要(Abstract)：
<正> To evaluate the clinic value of comb-ination of rest 99mTc-MIBI myocardial tomograaphy with mitroglycerin(NTG)sublingual administration in assessing myocardial stabilityRoutine rest 99mTc-MIBI myocardial tomography imaging wasperformed for 36 patients with coronary heart disease(12)with old eyocardral infarction,12 with unstable angina and12 with stable anginal,and 48 hours later NTG wasadministrated aublinggually(0.5mg)5 minutes before thetrace ingection,and then rest mycoardial imaging wasperformde again Showed 36 patients gad 111 segments ofhyperfusion in rest imaging,46 patients had improvement ofperfusion after NTG administration(41.4%).7 segments wereindentified as irreversible perfusion defects inpatients with UA.and without in SAConclusions:The administration of NTG before rest 99mTCMIBI SPECT may be a useful approach for predictingmyocardial viability be helpful for assessing patients'condition and direct treatment,The results require furtherstudy.
