What to Do in Case of a Heart Attack: Myocardial infarction is a severe and life-threatening disease that cannot be treated at home. It is essential to call emergency services immediately by dialing 120 and seek treatment at the hospital as quickly as possible. While waiting for the ambulance, try to have the patient rest in a semi-recumbent position with support behind them to reduce the heart's oxygen consumption. Quickly loosen the patient's collar to maintain clear breathing. If indoor air quality is poor, open windows for ventilation, but ensure the patient stays warm in cold weather. Avoid giving the patient water or medication at this time. If possible, administer oxygen. Heart attacks can potentially lead to malignant arrhythmias, causing loss of consciousness, arterial pulse disappearance, and cessation of breathing. If an automated external defibrillator (AED) is available nearby, use it to restore normal heart rhythm. If no AED is available, immediately initiate cardiopulmonary resuscitation (CPR) to revive the patient.
