Objective To analyse the clinical and angiographic characteristics of spontaneous reperfusion (SR) in AMI,and to evaluate its effect on short-term prognosis. Methods 112 consecutive AMI patients without intravenous thrombolytic therapy received emergent coronary angiography and primary PCI. The patients were divided into SR group (antegrade TIMI grade 2 - 3 flow) and non-SR group (antegrade TIMI grade 0 - 1 flow). The clinical, angiographic and prognostic features of the patients were analyzed. Results 31 patients (27. 7%) were in SR group,and there was no significant differentce in baseline clinical characteristics between the two groups. Compared with non-SR group,peak values of CK and CKMB, Ventricular wall motion abnormality and mortality were lower in SR group,ejection fraction was higher in SR group. Logistic regression analysis showed that there was good correlation between SR and peak value of CK, collaterals, ventricular wall motion abnormality and pre-dilation in PCI. Conclusion SR decreased infarction size,improved heart function and reduced 30-day mortality.
