It is recommended to call for help immediately whenever the symptoms of myocardial infarction occur. By calling the emergency medical services immediately, one can get the required treatment to take care of the symptoms of MI. The emergency services helps a lot in saving the life from primary ventricular fibrillation that occurs in over 10% of all infarctions during the first hour of symptoms. Also, the immediate treatment of myocardial infarction prevents further damage to the heart.
There are varying Emergency Medical Services (EMS) Systems available that differs in their ability to treat and evaluate patients with suspected AMI. Some of these system offer small first aid and early defibrillation. Other systems make use of highly trained paramedics that have advanced protocols and sophisticated technology. Paramedic services can provide sublingual nitro glycerine, morphine, aspirin, oxygen, and IV access. In fact, some of the advanced paramedic systems also perform 12-lead ECGs. If a STEMI is identified, the paramedic can contact the local PCI hospital and inform the physician, and staff about the suspected AMI. The paramedic services can also provide thrombolytic therapy and allows the reperfusion of the myocardium.
The primary PCI emerged as the recommended therapy for ST-segment elevation myocardial infarction and EMS plays a major role in reducing the time for the restoration of coronary artery blood flow. It does so by performing a 12-lead ECG in the field only and utilising this information for admitting the patient to the proper medical facility. Moreover, the 12-lead ECG can be made available to the receiving hospital that further saves time for making the informed decision before the arrival of the patient. For example, it helps in announcing the “cardiac alert” or “STEMI alert” that makes arrangement for the doctors and medical personnel augmentin in areas where staff is not present 24 hours a day.
