Early outcomes in patients with suspected acute coronary syndrome without persistent ST elevation, transported to a vascular center by ambulance

The aim was to study early outcomes in patients with suspected acute coronary syndrome without ST elevation who were transported by emergency to the vascular center.Material and Methods. We studied medical records from 396 patients with suspected acute coronary syndrome without ST elevation. A telephone survey of patients or their relatives was conducted within two months after the emergency call.Results. In-hospital diagnosis of acute coronary syndrome was confirmed only in 30.6% of patients with suspected acute coronary syndrome without ST elevation admitted to the vascular center. Cardiologists in the vascular center were ruling out diagnosis of acute coronary syndrome without ST elevation based on data of clinical examination and electrocardiography. During the following two months, 6.4% of the patients with ruled out diagnosis of acute coronary syndrome called emergency again; 2% of the patients were admitted with acute coronary syndrome to the vascular center; and 2.4% of the patients died at home.Conclusion. In real clinical practice, the assessment of myocardial necrosis biomarkers has been used not enough in cases of suspected acute coronary syndrome without ST elevation.
