When is percutaneous coronary intervention (PCI) preferred over fibrinolysis in acute myocardial infarction?

• A. After 12 hours of symptoms
• B. When the hospital is PCI-capable with short transport time
• C. If intrinsic heart damage is suspected
• D. Only in patients over 65 years of age

Answer: (B)

Percutaneous coronary intervention (PCI) is often preferred over fibrinolysis in the management of acute myocardial infarction when the hospital has the capability to perform PCI and the transport time to that facility is short. This preference primarily arises because PCI, when performed in a timely manner, can restore blood flow more quickly and effectively to the occluded coronary arteries than fibrinolytic therapy. Timeliness is crucial in the setting of acute myocardial infarction, as minimizing ischemic time can significantly improve patient outcomes and reduce the likelihood of complications. If a patient can be transported to a PCI-capable hospital swiftly, the benefits of the intervention outweigh the use of fibrinolysis, which might not lead to as effective a resolution of the blockage. Fibrinolysis is typically reserved for situations where there is a delay in receiving PCI or if PCI is not readily available, as it can expose patients to significant risks, such as bleeding. Thus, the criteria focused on the logistical advantages of PCI, rather than age or presumption of heart damage, make the choice in this scenario clear.
