Heart attack (myocardial infarction)

What is a heart attack?

When the blood flow to the heart is blocked, usually because fats and cholesterol have created an excess of plaque buildup in the coronary arteries, you can experience a heart attack.

A heart attack can be fatal – but there are many steps you can take and excellent treatments available to help prevent a heart attack.

What are the symptoms of a heart attack?

Not everyone experiences a heart attack the same way – there are multiple symptoms and varying degrees at which you can experience those symptoms.

With each of the following symptoms, understand that you could have mild symptoms over the course of a few days or suddenly experience a cardiac arrest. Be on the lookout for any one or all of the following symptoms:

  • Chest pain or discomfort, ranging from mild to severe
  • Pain in your shoulders, arms, chest, neck or jaw
  • Stomach pain, which may spread and feel like heartburn
  • Anxiety
  • Shortness of breath
  • Nausea and vomiting
  • Sweating and cold, clammy skin

Many heart attacks begin with slight, subtle symptoms. For example, you may have occasional but regular chest discomfort. Regardless of the severity of your symptoms, you must seek medical attention immediately.

Diagnosis of a heart attack

Once you report your symptoms to your physician, you will undergo a physical exam and report your medical history. You may also go through a series of tests which can include:

  • Electrocardiogram (EKG): checks the electric activity of your heart
  • Echocardiogram (ECHO): A sonogram of your heart to determine the condition of your heart valves, how well your heart pumps, and any issues with your heart muscle
  • Blood tests to determine levels of enzymes in your system

Once a detailed diagnosis is reached, your physician will determine your best treatment options. A heart attack or potential heart attack may indicate cardiovascular disease.
