Insights

High pre-interventional lesion stenosis (LS) and critical lesion length (LCS) predict late coronary in-stent restenosis (ISR). Stenosis over 87.5% is a strong predictor of ISR.

Area of Science:

  • Interventional Cardiology
  • Cardiovascular Research

Background:

  • Coronary in-stent restenosis (ISR) is a significant complication following percutaneous coronary intervention.
  • Predicting the risk of late ISR is crucial for optimizing patient outcomes.

Purpose of the Study:

  • To investigate the relationship between pre-interventional angiographic characteristics, specifically lesion stenosis (LS) grade and critical lesion length (LCS), and the prognosis of late ISR.
  • To identify key predictors of ISR development.

Main Methods:

  • Retrospective comparison of 110 patients with ISR and 109 patients without ISR.
  • Analysis of pre-interventional angiographic data, including LS grade and LCS.
  • Kaplan-Meier curve analysis and log-rank tests to assess the predictive value of LS and LCS.

Main Results:

  • Patients with ISR had significantly greater pre-interventional LS (P < .001) and longer LCS (P < .001) compared to those without ISR.
  • Pre-interventional LS >87.5% was 6.9 times more predictive of ISR than LCS >10.5 mm.
  • Higher ISR rates were observed in patients with initial LS >87.5% (P < .001) and LCS >10.5 mm (P < .001).

Conclusions:

  • Pre-interventional angiographic LS and LCS are significant predictors of late ISR.
  • An LS grade exceeding 87.5% is a strong independent predictor of late ISR development.

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...

Imaging Studies for Cardiovascular System VI: Calcium -Scoring CT

Calcium-Scoring CT ScanA calcium-scoring CT scan, also known as coronary artery calcium (CAC) scan, detects calcium deposits in the coronary arteries. This test assesses the risk of coronary artery disease (CAD), which can lead to cardiovascular events such as angina, heart failure, and sudden cardiac arrest.A calcium-scoring CT scan is generally recommended for individuals at intermediate risk of CAD without symptoms. It includes:Men aged 40-75 and women aged 50-75: Especially those with a...

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...

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...

Angina II: Classification01:27

Angina II: Classification

Angina, also known as angina pectoris, is a chest pain resulting from diminished blood flow to the heart muscle and is often a symptom of coronary artery disease. Angina presents several variants with distinctive attributes, etiologies, and therapeutic approaches. The main types of angina include stable, unstable, variant (Prinzmetal's), microvascular, intractable, and silent ischemia.Stable angina is caused by atherosclerosis, which leads to the formation of plaques that narrow the coronary...
