Insights

Bifurcation lesions during emergent percutaneous coronary intervention (PCI) for ST-elevation myocardial infarction (STEMI) are common, particularly in the left anterior descending artery. Provisional stenting offers a safe and effective treatment strategy with outcomes comparable to non-bifurcation lesions.

Area of Science:

  • Interventional Cardiology
  • Cardiovascular Research
  • Acute Coronary Syndromes

Background:

  • Bifurcation lesions are frequently encountered during emergent percutaneous coronary intervention (PCI) for ST-elevation myocardial infarction (STEMI).
  • Limited data exist on the clinical significance and management of these lesions in the STEMI setting.
  • This study aims to assess the impact of bifurcation lesions in emergent PCI for STEMI.

Purpose of the Study:

  • To evaluate the incidence and outcomes of bifurcation lesions in patients undergoing emergent PCI for STEMI.
  • To compare clinical characteristics, procedural success, and in-hospital events between patients with and without bifurcation lesions.

Main Methods:

  • Retrospective analysis of 391 patients undergoing primary or rescue PCI.
  • Comparison of clinical data, procedural success rates, and in-hospital cardiac events between patients with and without bifurcation lesions.
  • PCI strategy was determined by the operator.

Main Results:

  • Bifurcation lesions were present in 14% of patients, predominantly in the left anterior descending (LAD) artery (81%).
  • Provisional stenting was the primary approach, with a low rate of two-stent use (3%).
  • Procedural success and final TIMI-3 flow were similar, though bifurcation PCI required more contrast; no in-hospital major adverse cardiac events (MACE) were observed in the bifurcation group.

Conclusions:

  • Bifurcation lesions are common in emergent PCI for STEMI, especially involving the LAD.
  • The provisional stenting approach is safe and effective for these lesions.
  • Immediate outcomes for bifurcation lesions are comparable to non-bifurcation lesions in the STEMI setting.

Acute Coronary Syndrome I: Introduction

Acute Coronary Syndrome (ACS) encompasses a spectrum of heart conditions caused by sudden obstruction of coronary arteries, typically resulting from the rupture of an atherosclerotic plaque and subsequent thrombus (blood clot) formation. This obstruction can lead to partial or complete blockage of blood flow, causing varying degrees of myocardial ischemia or infarction.ACS includes the following clinical entities:Unstable Angina (UA)Non-ST-Elevation Myocardial Infarction (NSTEMI)ST-Elevation...

Acute Coronary Syndrome II: Pathophysiology and Clinical Manifestations

The pathophysiology of Acute Coronary Syndrome [ACD] involves several key processes:The main underlying cause of ACD is atherosclerosis, a chronic inflammatory disease characterized by the buildup of lipid-laden plaques within the coronary arteries.As the atherosclerotic plaque grows in the coronary artery, it may become unstable due to the formation of a lipid-rich core and a thin fibrous cap. Inflammatory cells within the plaque, such as macrophages, secrete enzymes that degrade the...

Acute Coronary Syndrome III: Diagnostic Studies

Diagnosing acute coronary syndrome or ACS begins with a thorough patient history. Notable symptoms include central, crushing chest pain radiating to the left arm, neck, jaw, or back, along with shortness of breath, sweating (diaphoresis), nausea, vomiting, dizziness, and palpitations.It is crucial to note any history of cardiac illnesses and assess risk factors, including age, gender, smoking, hypertension, diabetes, hyperlipidemia, and a sedentary lifestyle.During physical examination, vital...

Coronary Artery Disease V: Interprofessional Care

Interprofessional care for coronary artery disease includes pharmacological therapy and revascularization procedures.Pharmacological therapy for Coronary Artery Disease (CAD) aims to manage symptoms, prevent complications, and improve patient outcomes through various classes of medications:Antiplatelet Agents:Aspirin and Clopidogrel: These medications inhibit platelet aggregation, preventing blood clots, which is crucial for avoiding heart attacks and strokes. Doctors often prescribe these...
