Insights

Patients undergoing percutaneous coronary intervention for ST-elevation myocardial infarction were more likely to receive bare-metal stents (BMS) if uninsured, had peripheral vascular disease, or worse left ventricular ejection fraction (LVEF). These factors predict BMS use in STEMI patients.

Area of Science:

  • Cardiology
  • Interventional Cardiology
  • Health Services Research

Background:

  • Bare-metal stent (BMS) use in ST-elevation myocardial infarction (STEMI) patients undergoing primary percutaneous coronary intervention (PCI) is linked to increased adverse cardiac events.
  • Understanding predictors of BMS use is crucial for optimizing patient care and outcomes in STEMI.

Purpose of the Study:

  • To identify clinical characteristics that predict the use of BMS versus drug-eluting stents (DES) in patients with STEMI undergoing primary PCI.

Main Methods:

  • Prospective data collection from 1394 STEMI patients undergoing primary PCI across four New York State academic medical centers (2004-2007).
  • Comparison of demographics, medical history, procedural details, and in-hospital outcomes between BMS and DES groups.
  • Multivariate analysis to determine independent predictors of BMS implantation.

Main Results:

  • 20.8% of patients received BMS (n=290), while 79.2% received DES (n=1104).
  • BMS recipients had higher rates of prior coronary artery bypass graft surgery, peripheral vascular disease, diabetes, Hispanic ethnicity, and were more likely to be uninsured.
  • Independent predictors for BMS use included uninsured status (OR, 2.81), peripheral vascular disease (OR, 1.96), and lower left ventricular ejection fraction (LVEF) (OR, 0.98).

Conclusions:

  • In STEMI patients undergoing primary PCI, lack of health insurance, presence of peripheral vascular disease, and reduced LVEF are independently associated with higher likelihood of BMS implantation.
  • These findings highlight socioeconomic and clinical factors influencing stent selection in acute myocardial infarction.

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 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...

Peripheral Artery Disease (PAD) is characterized by narrowed arteries that diminish blood flow to the extremities. Effective management of PAD requires an interprofessional approach involving various healthcare professionals. The critical aspects of interprofessional care for PAD patients focus on risk factor modification, drug therapy, exercise therapy, nutrition therapy, critical limb ischemia care, and interventional radiology and surgical procedures.The primary treatment goal for PAD...
