Aacute myocardial infarction

What is acute myocardial infarction?

Acute myocardial infarction is the medical name for a heart attack. A heart attack is a life-threatening condition that occurs when blood flow to the heart muscle is abruptly cut off, causing tissue damage.

 This is usually the result of a blockage in one or more of the coronary arteries. A blockage can develop due to a buildup of plaque, a substance mostly made of fat, cholesterol, and cellular waste products.

Call 911 right away if you think that you or someone you know may be having a heart attack.

What are the symptoms of acute myocardial infarction?

While the classic symptoms of a heart attack are chest pain and shortness of breath, the symptoms can be quite varied. The most common symptoms of a heart attack include:

• pressure or tightness in the chest
• pain in the chest, back, jaw, and other areas of the upper body that lasts more than a few minutes or that goes away and comes back
• shortness of breath
• sweating
• nausea
• vomiting
• anxiety
• a cough
• dizziness
• a fast heart rate

It’s important to note that not all people who have heart attacks experience the same symptoms or the same severity of symptoms. Chest pain is the most commonly reported symptom among both women and men. However, women are more likely than men to have:

• shortness of breath
• jaw pain
• upper back pain
• lightheadedness
• nausea
• vomiting

In fact, some women who have had a heart attack report that their symptoms felt like the symptoms of the flu.

What causes acute myocardial infarction?

Your heart is the main organ in your cardiovascular system, which also includes different types of blood vessels. Some of the most important vessels are thearteries. They take oxygen-rich blood to your body and all of your organs. Thecoronary arteries take oxygen rich blood specifically to your heart muscle. When these arteries become blocked or narrowed due to a buildup of plaque, the blood flow to your heart can decrease significantly or stop completely. This can cause a heart attack. Several factors may lead to a blockage in the coronary arteries.

Bad cholesterol

Bad cholesterol, also called low-density lipoprotein (LDL), is one of the leading causes of a blockage in the arteries. Cholesterol is a colorless substance that’s found in the food you eat. Your body also makes it naturally. Not all cholesterol is bad, but LDL cholesterol can stick to the walls of your arteries and produce plaque. Plaque is a hard substance that blocks blood flow in the arteries. Blood platelets, which help the blood to clot, may stick to the plaque and build up over time.

Saturated fats

Saturated fats may also contribute to the buildup of plaque in the coronary arteries. Saturated fats are found mostly in meat and dairy products, including beef, butter, and cheese. These fats may lead to an arterial blockage by increasing the amount of bad cholesterol in your blood system and reducing the amount of good cholesterol.

Trans fat

Another type of fat that contributes to clogged arteries is trans fat, or hydrogenated fat. Trans fat is usually artificially produced and can be found in a variety of processed foods. Trans fat is typically listed on food labels as hydrogenated oil or partially hydrogenated oil.
