Abstract：Objective To explore the correlation between symptom onset-to-first medical contact (SO-to-FMC) time and prognosis in patients with acute ST-elevation myocardial infarction (STEMI). Methods 147 patients with STEMI undergoing percutaneous coronary intervention (PCI) were recruited and divided into A group (≤90 min, 64 cases) and B group (>90 min, 64 cases) according to SO-to-FMC time. The medical records and laboratory examination results were recorded. And SO-to-FMC time, medical contact to balloon (FMC2B) time and the clinic to balloon (D2B) time were recorded too. The mortality and cardiovascular events after discharge were followed up. Logistic regression analysis were used to analyze the risk factors for cardiovascular events after PCI. Results There was no significant difference in the FMC2B time and D2B time between A group and B group (both P>0.05). The cardiac mortality and death rate in group A were 1.20% and 2.41%, respectively, which were significantly lower than those in group B (7.81%, 14.06%, both P<0.05). Result of multivariate analysis showed that SO-to-FMC, FMC2B, D2B and age were independent risk factors for cardiovascular events after PCI in STEMI patients. Conclusion SO-to-FMC is an independent risk factor for cardiovascular events after PCI in STEMI patients. Shortening SO-to-FMC is important for improving the prognosis of patients.
