Background  Fibrinolytic therapy is the main reperfusion therapy for most STEMI patients in several countries. Current practice guidelines recommended routine early pharmacoinvasive (within 3–24 h after successful fibrinolysis, however it cannot be performed in timely fashion due to limitation of PCI-capable hospitals. This study aimed to evaluate the prognostic utility of the GRACE score in patients receiving delayed intervention after successful fibrinolysis in non PCI-capable hospital.    Methods  We retrospectively analysed the data from the Maharaj Nakorn Chiang Mai Hospital acute ST-elevation myocardial infarction (STEMI) registry during the period 2007–2012. The STEMI patients who had successfully fibrionolysis in non PCI-capable hospital and received delayed PCI (during 24 h to 14 days after successful fibrinolytic therapy) at Maharaj Nakorn Chiang Mai hospital were included. The primary end point for this analysis was the composite outcomes, which included all-cause mortality, re-hospitalization with acute coronary syndrome (ACS), re-hospitalization with heart failure (HF) and stroke at 1 and 6-month.    Results  A total of 152 patients were included. 88 patients and 64 patients were in low GRACE group (GRACE risk score ≤ 125) and intermediate to high GRACE group (GRACE risk score above 126), respectively. The median time from fibrinolysis to coronary intervention in low GRACE group was 8.5 days (interquartile range, 4.6–10.9) and 7.9 days (interquartile range,3.2,12.0) in intermediate to high GRACE group ( p  = 0.482). At 1 month, the composite cardiovascular outcome at 1 month occurred in 2 patients (2.3 %) in low GRACE group and 10 patients (15.6 %) in intermediate to high GRACE group ( P  = 0.003). During 6 months, the composite cardiovascular outcomes occurred in 6 patients (6.8 %) in low GRACE group and 12 patients (18.7 %) in intermediate to high GRACE group ( P  = 0.024). The cumulative of composite cardiovascular outcome was significant higher in intermediate to high GRACE group than in low GRACE group (Hazard ratio: 2.97, 95 % CI 1.11–7.90;  p  = 0.030).    Conclusion  The long delay pharmacoinvasive strategy in intermediate to high GRACE score after successful fibrinolysis in non PCI-capable facilities were associated with worse cardiovascular outcomes than the patients with low GRACE score at 1 and 6 months. GRACE risk score may be helpful and guided the clinicians in non PCI-capable center in early transferred to early intervention in STEMI patients after fibrinolytic therapy.
