Insights

Coronary artery bypass grafting patients in Iran had a low prevalence of significant carotid artery disease. Preoperative screening for carotid stenosis is recommended to reduce perioperative stroke risk.

Area of Science:

  • Cardiovascular Surgery
  • Vascular Surgery
  • Diagnostic Imaging

Background:

  • Coronary artery bypass grafting (CABG) is a common global procedure.
  • Carotid artery stenosis poses a perioperative stroke risk for CABG patients.
  • Preoperative carotid artery assessment is often recommended to mitigate stroke risk.

Purpose of the Study:

  • To evaluate the prevalence of carotid artery disease in patients undergoing CABG.
  • To assess carotid artery wall thickness via ultrasonography.
  • To identify risk factors associated with carotid artery disease in this population.

Main Methods:

  • 271 consecutive patients undergoing CABG were included.
  • Preoperative ultrasonography was used for carotid artery assessment.
  • Patient demographics and carotid artery findings were analyzed.

Main Results:

  • Low prevalence of significant (<50%) and critical (<70%) internal carotid artery stenosis was observed (1.8% and 1.1%).
  • Plaque prevalence in common carotid arteries did not differ by gender.
  • Left internal carotid artery stenosis was more common in men, and plaque was associated with older age.

Conclusions:

  • Elective CABG patients in Iran exhibit a low prevalence of significant carotid artery disease.
  • Findings suggest a potentially lower risk of perioperative stroke from carotid stenosis in this cohort.
  • Further research may refine screening protocols based on regional prevalence data.

Coronary Artery Disease I: Introduction

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...

Coronary Artery Disease IV: Preventive Measures

Effective preventive measures for coronary artery disease (CAD) focus on controlling modifiable risk factors, including cholesterol abnormalities and lifestyle changes.Cholesterol ManagementFirst, the Mediterranean diet and the American Heart Association advocate for maintaining low-density lipoprotein (LDL) cholesterol levels below 100 mg/dL, with a more stringent recommendation of below 70 mg/dL for individuals at high risk. LDL cholesterol, often termed "bad cholesterol," can lead to the...

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 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 III: Clinical Manifestations

Coronary Artery Disease (CAD) is a primary health risk worldwide, leading to significant morbidity and mortality. The condition arises from the buildup of atherosclerotic plaques within the coronary arteries, resulting in diminished blood supply to the heart muscle.The clinical manifestations of CAD vary widely, from asymptomatic stages to severe, life-threatening conditions. Understanding these manifestations is crucial for early diagnosis and effective management.Angina Pectoris: The Warning...
Ischemic Heart Disease: Overview01:17

Ischemic Heart Disease: Overview

Ischemic heart disease occurs when the heart's blood supply dwindles, causing an ominous lack of oxygen and nutrients. This deficiency, stemming from reduced or obstructed blood flow, spells danger, leading to heart muscle damage and dysfunction.
Atherosclerosis, the primary malefactor, orchestrates this dangerous condition. It manifests as the accumulation of fatty deposits, akin to insidious plaques, within arterial walls. As time elapses, these plaques metamorphose, hardening and narrowing...
