Heart attacks — also called myocardial infarctions — are very common in the United States.

What are the causes of a heart attack?
The most common motive of a heart attack is a blockage in one of the arteries close to the heart.
This can end result from coronary heart disease, in which plaque — made up of cholesterol and other materials — collects in the arteries, narrowing them. Over time, this can obstruct the float of blood.
Less frequent causes include:
** The misuse of drugs, such as cocaine, which reasons the blood vessels to narrow.
** Low oxygen stages in the blood, due, for example, to carbon monoxide poisoning.
What are the risk factors for heart attack?
As the (CDC) note, the following can increase the risk of a heart attack:
*high cholesterol levels
*high blood pressure
*other health conditions, such as obesity or diabetes
*having a diet high in processed foods and added fats, sugars, and salt
*low activity levels
*genetic factors and family history
*a high alcohol intake
*high levels of stress
Often, a heart attack results from a combination of factors. People with high blood pressure or a history of heart disease or cardiovascular disease also have an increased risk of a heart attack. Information About Heart Attack

*electrocardiography, to measure electrical activity in the heart
*blood tests, which can confirm that a heart attack has occurred
*cardiac catheterization, which enables a doctor to examine the inside of the heart
Tests and treatments:
Nowadays, many people survive heart attacks, due to effective treatment. Delaying treatment, however, dramatically reduce the chances of survival.

- Arrhythmia: The heart beats irregularly, either too fast or too slowly.
- Edema: Fluid accumulates and causes swelling in the ankles and legs.
- Aneurysm: Scar tissue builds up on the damaged heart wall, which causes thinning and stretching of the heart muscle, eventually forming a sac. This can also lead to blood clots.
- Angina: Insufficient oxygen reaches the heart, causing chest pain.
- Heart failure: The heart can no longer pump effectively, leading to fatigue, difficulty breathing, and edema.
- Myocardial rupture: This is a tear in a part of the heart, due to damage caused by a heart attack.
Ongoing treatment and monitoring can help reduce the risk of these complications.
There are various ways to lower the risk of a heart attack. The American Heart Association advises people to make heart health a priority.
Ways to do this include:
*managing diabetes, high cholesterol levels, high blood pressure, and other conditions
