Heart Attack Q & A

What is a heart attack?

A heart attack, also called a myocardial infarction, happens when there’s a blockage to the heart’s blood supply. Without the oxygen that blood carries, the heart muscle quickly begins to die.

Heart attacks are medical emergencies that require prompt care. The longer your heart goes without oxygen, the more serious the damage.

What are the symptoms of a heart attack?

People experience heart attacks differently. Common heart attack symptoms include:

  • Chest pain that may travel into the neck, jaw, and one or both arms
  • Weakness or lightheadedness
  • Dizziness
  • Shortness of breath
  • Cold sweats
  • Nausea and vomiting

If you experience these symptoms or think you may be having a heart attack, call 911 or your local emergency number immediately. 

What causes heart attacks?

Atherosclerosis, which is a buildup of plaque in the arteries, is one of the most common causes of heart attacks. Other conditions that can cause a heart attack include blood clots and torn blood vessels.

What complications are associated with heart attacks?

A heart attack can cause several complications. When you have a heart attack, it disrupts your heart’s normal rhythm. This may cause an arrhythmia, or an abnormal heartbeat.

Other possible complications include leaks within the valves of the heart and heart failure, which is life-threatening.

How is a heart attack diagnosed?

Most of the time, an emergency room doctor makes the initial heart attack diagnosis. Your Arizona Heart Arrhythmia Associates provider can also diagnose a heart attack or determine if you’ve had one in the past by performing a physical exam and reviewing your medical history. 

They may also conduct multiple tests, including:

  • Electrocardiogram (EKG)
  • Echocardiogram
  • Cardiac catheterization
  • Holter monitor or event monitor
  • Cardiac stress test

These tests help your cardiologist determine the exact cause of your heart attack so they can initiate the most appropriate course of treatment. 

How is a heart attack treated?

Treatment for a heart attack depends on the underlying cause and severity of your condition. Common heart attack treatments include:

  • Medications
  • Balloon angioplasty
  • Stent placement
  • Pacemaker or defibrillator implantation

If your heart attack was severe, surgery may be necessary. Heart attacks that cause permanent damage may require a heart transplant.
