[Evaluation of transfer parameters in patients admitted to our hospital with ST-elevation myocardial infarction]. / ST-yükselmeli miyokart enfarktüsü ile basvuran hastalarin transfer parametrelerinin degerlendirilmesi.

ABSTRACT

OBJECTIVE: Acute coronary syndrom (ACS) is a common disease that causes severe morbidity and mortality. The most important aspect of ST-elevation myocardial infarction (STEMI) as a subgroup of ACS treatment is the rapid reperfusion of arteries. Successful results depend not only on the experience of the center but also on the rapidity in which reperfusion is achieved. In our study, the transfer parameters were evaluated in patients who were admitted to our hospital with STEMI. METHODS: Two hundred consecutive patients (160 males, 40 females) who underwent primary percutaneous coronary intervention (PCI) for acute STEMI between January 2011 and March 2013 were included in our study. Transfer parameters of symptom-to-reperfusion treatment, clinical characteristics, and laboratory parameters were recorded. RESULTS: Thirty-six patients were admitted to our hospital with ambulances; 70 patients were admitted to centers without PCI capability, with a mean transfer time to our hospital of 73.9±12.5 min. Median pain-to-first medical contact time was 105 min (range 5-600 min), and average first medical contact-to-balloon time was 115.5 min (range 20-414 min). Total pain-to-balloon time in females was significantly higher than males (246 min [range 70-840 min], 195 min [range 45-684 min], respectively, p=0.032). Mean pain-to-balloon time was significantly lower in patients delivered to the hospital by ambulance than in patients admitted to emergency departments independently (185 min [range 45-439 min], 248 min [range 65-840 min], respectively, p=0.017). CONCLUSION: In this study, our hospital door-to-balloon time was found compatible with the target specified in the European Society of Cardiology and American College of Cardiology STEMI guidelines; however, first medical contact-to-balloon time was found to be above that advised by the current guidelines.
