What to Know About Heart Attacks?!
A heart attack, also called a myocardial infarction, occurs when a section of the heart muscle dies or gets damaged because of reduced blood supply. Coronary Artery Disease (CAD) occurs when a substance called plaque builds up in the arteries that supply blood to the heart (called coronary arteries). CAD is the main cause of heart attack. The five major symptoms of a heart attack are—
Feeling weak, light-headed, or faint.
Chest pain or discomfort.
Pain or discomfort in arms or shoulder.
Shortness of breath.
If you believe you or someone are experiencing the symptoms of a heart attack it is important to to call 9-1-1 immediately. Otherwise, further damage to the heart muscle can occur and an irregular heart rhythm may develop.
Bystanders who have been trained to perform cardiopulmonary resuscitation (CPR) or use a defibrillator may be able to help the victim until emergency medical personnel arrive. At the hospital, doctors will then perform tests to determine whether a heart attack is occurring and decide on the best treatment.
Remember, it’s important to recognize these symptoms and call for help because the chances of surviving a heart attack are greater when emergency treatment begins quickly.
