PREHOSPITAL STAGE OF MEDICAL AID TO PATIENTS WITH ACUTE CORONARY SYNDROME AND ELEVATED ST SEGMENT
We studied effect of time on the outcome of acute coronary syndrome and elevated ST segment at the prehospital stage. Logistic regression analysis revealed two time-dependent predictors: «symptom-needle» time and total call service time. In patients undergoing prehospital thrombolysis, these indices (88 and 85 min respectively) reliably predicted the probability of fatal outcome. Their values of 71 and 77 min respectively predicted the risk of unfavourable outcome. The total call service time may serve as an indicator of the quality of work of an ambulance crew at the prehospital stage of management of acute coronary syndrome with elevated ST segment.
