Learn the basic of a heart attack here.
What is a heart attack?
A heart attack, in medical terms also called myocardial infarction, is a serious medical emergency where the coronary artery that supplies the heart muscle with blood is completely or partially closed by a blood clot. As the heart loses blood supply and oxygen, part of the muscle can die or get damaged, causing chest pain and instability in the electrical activity of the heart muscle tissue. The most serious complication of a heart attack is the occurrence of a rhythm disturbance in the heart, also called ventricular fibrillation, that can lead to cardiac arrest. A cardiac arrest is when the heart malfunctions and stops beating unexpectedly.

The risk of having a heart attack increases when a man is 45 and a woman is more than 55. There are many different elements increasing the risk of being victim of a heart attack, such as high blood cholesterol levels, unhealthy dieting, diabetes, heart surgery, overweight, hypertension, foregoing history of heart attack, being inactive, smoking and stress.

How do you treat a heart attack?
There are two ways to treat a heart attack: medication based and procedure based.
The first, medication based method of treating a heart attack is thrombolysis, also known as the clot buster. It involves a procedure where the paramedic or doctor will inject medicine into a vein to soften the blood to reestablish blood supply to the heart. This treatment can be started in the ambulance.
The other method is primary percutaneous coronary intervention (PPCI) where the doctor opens the blocked coronary artery, reinstating blood supply to the part of the heart that is lacking blood. This method saves as much of the heart muscle as possible but as it is surgery, this treatment can only be done in the hospital.
