Heart Attack Q & A

What causes a heart attack?

You have a heart attack, or myocardial infarction when the blood flow to your heart becomes significantly blocked or cut off. 

Without blood, your heart doesn’t get enough oxygen, a condition called ischemia. Ischemia quickly damages or kills part of your heart muscle, which in turn causes your heart attack.

Getting quick treatment to restore blood flow limits the damage to your heart. After heart muscle dies, however, the damage is permanent.

What health condition leads to a heart attack?

Coronary artery disease causes heart attacks. This condition develops as cholesterol, and other fats, build up on the wall of one of your coronary arteries. Over time, the cholesterol plaque gets larger and hardens, eventually limiting or blocking blood flow.

You can also have a heart attack when the plaque ruptures and causes a blood clot. The clot suddenly expands the plaque enough to interfere with blood flow.

What symptoms occur when I have a heart attack?

Each person experiences a heart attack differently. Some have mild symptoms, while others develop severe pain. You may only feel chest pain, or you may have shortness of breath without chest pain.

The symptoms you may experience include:

  • Chest pain
  • Chest pressure or tightness
  • Pain in your neck, jaw, shoulders, or back
  • Shortness of breath
  • Sudden indigestion or heartburn
  • Nausea or abdominal pain
  • Lightheadedness or dizziness
  • Cold sweat
  • Fatigue

While women and men often have chest pain, women are more likely to experience less common symptoms, such as indigestion, fatigue, and pain in their upper back or shoulder.

Call 9-1-1 or your local emergency service as soon as you experience any symptoms of a heart attack.

How do cardiologists treat a heart attack?

Your treatment focuses on restoring blood flow and preventing more damage to your heart. Emergency room physicians give you medications to dissolve blood clots and thin your blood. You may also get medicines to prevent new blood clots, relieve your chest pain, reduce your heartbeat, and lower your blood pressure.

Depending on the severity of your coronary artery disease, you may also have an interventional procedure to clear away the blockage or bypass the clot.

Dr. Fernandes has extensive experience performing interventional procedures such as angioplasty and stenting. She also provides exceptional ongoing care to restore your health after a heart attack, creating personalized treatment plans that incorporate lifestyle changes and medical therapies.
