Heart Attack: Symptoms, Causes, and Treatment

A heart attack, also known as a myocardial infarction, is a serious medical emergency that occurs when the blood supply to the heart is blocked. Without enough blood, the heart muscle can become damaged and may stop working properly. Heart attacks can be life-threatening and require immediate medical attention.

Keyphrase: “heart attack”

What are the symptoms of a heart attack?

The symptoms of a heart attack can vary from person to person, but common signs include:

  • Chest pain or discomfort: This may feel like heavy pressure, squeezing, or pain in the chest. It may also spread to the arms, back, neck, or jaw.
  • Shortness of breath: This may occur with or without chest pain.
  • Nausea or vomiting: Some people may experience nausea or vomiting during a heart attack.
  • Sweating: Some people may break out in a cold sweat during a heart attack.
  • Lightheadedness or dizziness: Some people may feel faint or lightheaded during a heart attack.
  • Fatigue: Some people may feel extremely tired or weak before or during a heart attack.

It’s important to note that not everyone experiences all of these symptoms, and some people may not have any symptoms at all. This is known as a “silent” heart attack.

What causes a heart attack?

A heart attack is usually caused by a blockage in one or more of the coronary arteries, which supply blood to the heart muscle. The most common cause of a heart attack is the build-up of plaque in the arteries, which can eventually rupture and form a blood clot. This clot can block the flow of blood to the heart, leading to a heart attack.


Other factors that can increase the risk of a heart attack include:

  • High blood pressure
  • High cholesterol
  • Diabetes
  • Smoking
  • Lack of physical activity
  • Obesity
  • Family history of heart disease
  • Age (men over 45 and women over 55 are at increased risk)

How is a heart attack treated?

Treatment for a heart attack typically involves medications and procedures to restore blood flow to the heart. This may include:

  • Aspirin: Aspirin can help to thin the blood and prevent blood clots from forming.
  • Blood thinners: Blood thinners can help to prevent the formation of blood clots.
  • ACE inhibitors: These medications can help to relax and widen the blood vessels, improving blood flow to the heart.
  • Beta-blockers: These medications can help to slow the heart rate and reduce the workload on the heart.
  • Statins: Statins can help to lower cholesterol levels, which can reduce the risk of plaque build-up in the arteries.

In some cases, a procedure such as angioplasty or coronary artery bypass surgery may be necessary to restore blood flow to the heart.
