Abstract:
Objective To assess the values of TIMI myocardial perfusion grade (TMP), corrected TIMI frame count (CTFC), sum-ST-segment resolution (sumSTR), max-ST-segment deviation (maxSTE) in judging myocardial perfusion and to predict their clinical outcomes. Methods In 77 patients with AMI, methods of TMP, maxSTE, sumSTR, CTFC were used to judge myocardial perfusion grade respectively immediately after PCI. Sixty-five patients underwent 99m Tc-MIBI/ 18 FDG DISA SPECT within one months after PCI, in-hospital heart faiures and cardiac events in the 6 months were recorded. Results Compared with 99m Tc-MIBI/ 18 FDG DISA SPECT, sensitivity, specificity, accuracy of TMP, CTFC, maxSTE, sumSTR was calculated. Sensitivity, specificity, accuracy of maxSTE were 80%, 85.7%, 83.1% respectively; Those of TMP were 73.3%, 80%, 76.9%, respectively. But those of CTFC (40), CTFC (30), sumSTR (30%), sumSTR (50%) were lower. By multivariate analysis of TMP0/1, maxSTE was the independent risk factor for 6-month cardiac events. Conclusion TMP, maxSTE may better assess myocardial perfusion, and accurately predict the outcome in 6-months.
