Heart attack quality scores

A heart attack (also called acute myocardial infarction, or AMI) occurs when the arteries leading to the heart become blocked, depriving the heart of oxygen.

The quality scores below tell you how well Duke hospitals followed recommended guidelines for certain heart attack treatments, and allow you to compare Duke's scores to national and state averages.

Heart attack patients given PCI within 90 minutes of arrival

  • *The U.S. average includes all reporting hospitals in the United States.
  • **The N.C. average includes all reporting hospitals in the state of North Carolina.
  • ***The number of cases is too small (less than 25) to reliably predict hospital performance.

What does this measure?

The percentage of eligible heart attack patients who received percutaneous coronary interventions (PCI) to open blocked blood vessels within 90 minutes of their arrival at the hospital. The term PCI can refer to angioplasty, stenting, or atherectomy.

Why is this important?

Heart attacks often occur when blood clots cause blockages in blood vessels, depriving the heart of sufficient oxygen. PCI procedures open blocked vessels and help prevent further damage to the heart.

They can also increase a patient’s chance of surviving a heart attack. The earlier PCI is performed, the more effective it is in improving patient outcomes.
