The medical treatment for STEMI and cardiogenic shock is affected due to the communication gap between the paramedics and doctors while patients are transferred from the emergency department to the cath lab. The effects of pre-hospital system delays on the treatment efficacy of STEMI patients are mortal.
According to Biomed Central, the time from the first medical contact (FMC) to the first ECG performed by the EMS should be ≤10 min in order to quickly diagnose STEMI. Also, the time from FMC to mechanical reperfusion of the occluded artery should be ≤90 min and in some patients (high-risk patients with a large MI and with symptoms lasting < 2 h) even ≤60 min.
