Percutaneous coronary intervention: the story so far

Area of Science:

• Cardiovascular Medicine
• Interventional Cardiology

Background:

• Percutaneous coronary intervention (PCI) use has surged over 20 years for ischemic coronary artery disease (CAD).
• Technological advancements like drug-eluting stents and improved pharmacology have enhanced PCI outcomes.
• Increased mortality with drug-eluting stents necessitates careful consideration.

Purpose of the Study:

• To review the advancements in PCI for ischemic CAD.
• To highlight the impact of new technologies and pharmacology on PCI.
• To address recent concerns regarding drug-eluting stent safety.

Main Methods:

• Literature review of PCI advancements over the past two decades.
• Analysis of technological improvements including drug-eluting stents and distal protection devices.
• Evaluation of pharmacological refinements, such as glycoprotein IIb/IIIa inhibitors.

Main Results:

• PCI procedural success, safety, and durability have markedly improved.
• Drug-eluting stents have contributed to improved outcomes but raised mortality concerns.
• Current understanding of outcomes necessitates cautious application of new technologies.

Conclusions:

• PCI has become a highly effective treatment for ischemic CAD.
• Physicians must weigh the benefits of drug-eluting stents against potential mortality risks.
• Adherence to Food and Drug Administration (FDA) guidelines is crucial for safe drug-eluting stent deployment pending further research.
