Abstract:
Objective To assess the predictive value of coronary angiography TIMI myocardial perfusion grade (TMPG), electrocardiogram (ECG) single-lend ST segment resolution (STR), ECG Max-ST-segment deviation (MaxSTE) on judging myocardial reperfusion after primary angioplasty in the patients with acute myocardial infarction (AMI). Methods Primary percutaneous coronary intervention(PCI) was performed in 42 patients within 12 hours after AMI onset. Coronary angiography and ECG was done before and after angioplasty. TMPG, ECG single-leed STR and MaxSTE were used to assess myocardial reperfusion immediately after PCI. Myocardial perfusion scan was examined in all the patients using99mTc-MIBI SPECT on day 7±2. Results Compared with the level of myocardial perfusion demonstrated in myocardial scan of 99mTc-MIBI SPECT, the sensitivity, specificity and accuracy of TMPG, single-lead STR and MaxSTE was calculated. The sensitivity of TMPG, single-lead STR and MaxSTE was 93.75%, 87.50% and 81.25%, respectively, the specificity of them was 20.00%, 80.00% and 80.00%, respectively, and the accuracy was 76.19%, 85.71% and 80.95%, respectively. The findings in single-lead STR and MaxSTE matched well with the results of myocardial scan of 99mTc-MIBI SPECT. Conclusion In the patients suffering from AMI treated with PCI, ECG is an effective method to assess myocardial tissue reperfusion.
