Insights

Serum amyloid A (SAA) predicts infarct-related artery (IRA) patency in ST-elevation myocardial infarction (STEMI) patients undergoing percutaneous coronary intervention (PCI). Higher SAA levels indicate a greater likelihood of IRA occlusion before PCI.

Area of Science:

  • Cardiology
  • Biomarkers
  • Interventional Cardiology

Background:

  • Serum amyloid A (SAA) is recognized as a cardiovascular risk factor.
  • SAA may predict infarct-related artery (IRA) patency in ST-elevation myocardial infarction (STEMI) patients.
  • Percutaneous coronary intervention (PCI) is a standard treatment for STEMI.

Purpose of the Study:

  • To investigate the association between pre-PCI SAA levels and IRA patency in STEMI patients.
  • To evaluate SAA as a potential predictor of IRA patency.
  • To determine the diagnostic performance of SAA for IRA patency.

Main Methods:

  • Serum amyloid A (SAA) levels were measured in 363 STEMI patients undergoing PCI.
  • Patients were categorized into occlusion (TIMI 0-2) and patency (TIMI 3) groups based on IRA flow.
  • Receiver operating characteristic (ROC) curve analysis and multivariate logistic regression were employed.

Main Results:

  • Pre-PCI SAA levels were significantly higher in patients with IRA occlusion compared to those with patency.
  • SAA demonstrated good diagnostic performance with an area under the ROC curve (AUC) of .833.
  • SAA was identified as an independent predictor of IRA patency (OR = 1.041, P < .001).

Conclusions:

  • Serum amyloid A (SAA) is a potential predictor of infarct-related artery (IRA) patency in STEMI patients prior to PCI.
  • Elevated SAA levels are associated with IRA occlusion.
  • SAA measurement could aid in risk stratification and treatment decisions for STEMI patients.

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...

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...

Atherosclerosis II: Clinical Manifestations and Diagnostic Tests

Atherosclerosis is a progressive disorder that leads to the thickening and narrowing of arterial walls due to plaque buildup. This condition can cause various symptoms depending on the arteries affected:Coronary Artery Disease (CAD): This condition affects the coronary arteries and may lead to chest pain (angina), shortness of breath (dyspnea), heart attacks, and other heart disease symptoms.Cerebrovascular Disease: This affects blood flow to the brain, causing transient ischemic attacks (TIAs)...

Coronary Artery Disease (CAD): An Overview with Scientific InsightsCoronary Artery Disease (CAD), often referred to as C-A-D, is a prevalent blood vessel disorder classified under the broader category of atherosclerosis. Atherosclerosis is a pathological process characterized by the hardening and narrowing of arteries due to the accumulation of atherosclerotic plaques. These plaques are composed of cholesterol, fatty substances, inflammatory cells, calcium, and fibrin, reducing blood flow to...
