Delay of Fibrinolysis in ST- Elevation Myocardial Infarction: Results of an Investigation Conducted in a Single Center in Sousse Tunisia.

BACKGROUND

The aim of our study was to assess the delay of fibrinolysis in ST elevation myocardial infarction (STEMI) in our region and to identify characteristics associated with prolonged delay.

PATIENTS AND METHODS

We analyzed clinical characteristics of a prospective cohort of unselected patients admitted for (STEMI). The study was conducted over three years 2007-2009 and 250 patients were included in a single center without capability of percutaneous coronary intervention.

RESULTS

The mean age of our patients was 58±13, 7 years. Ninety percent of our patients consult directly the emergency department and 61, (5%) of them were admitted within first 6 hours of onset of symptoms. Median time to reperfusion was 46 min. Predictor of this long delay to initiate fibrinolysis were inter-department decision OR 6; 95% CI 3,48-10,34, diabetes OR 2,25; 95% CI 1,28-3,96 age >58,4 years OR 1,97; 95% CI 1,19-3,25 and transfer from regional hospital to our center OR 1,78; 95% 1,03-3.07.

CONCLUSION

These results suggest that improvement in organization health care system can shorten delay to fibrinolysis in a center without percutaneous coronary intervention capability.
