Insights

Celiac disease (CD) patients have increased risks for coronary artery disease (CAD), particularly males and those with hyperlipidemia or type 2 diabetes. Iron deficiency anemia is also a significant CAD risk factor in CD patients.

Area of Science:

  • Cardiology
  • Gastroenterology
  • Epidemiology

Background:

  • Coronary artery disease (CAD) association with celiac disease (CD) is recognized, but shared risk factors remain poorly understood.
  • Established CAD risk factors include hypertension, hyperlipidemia, type 2 diabetes, obesity, and tobacco use.
  • Limited literature exists on specific risk factors linking CD and CAD.

Purpose of the Study:

  • To identify demographic differences between CD patients with and without CAD.
  • To analyze CAD risk factors within the CD patient population.
  • To compare CAD risks in CD patients versus matched non-CD patients.

Main Methods:

  • Nationwide retrospective case-control study utilizing the National Inpatient Sample (NIS) database (2016-2018).
  • Identified patients with a diagnosis of CD and analyzed sociodemographic and clinical risk factors for CAD.
  • Compared CD patients with CAD (CD-CAD) to a matched cohort of non-CD patients with CAD.

Main Results:

  • Of 23,441 CD hospitalizations, 18% had CAD. Key risk factors in CD patients included hypertension, hyperlipidemia, type 2 diabetes, and family history of CAD; tobacco use was not significant.
  • Female CD patients had 55% lower odds of CAD. Hyperlipidemia, hypertension, and type 2 diabetes significantly increased CAD odds in CD patients.
  • CD-CAD patients showed higher prevalence of iron deficiency anemia compared to non-CD CAD patients.

Conclusions:

  • Males and White individuals are at higher CAD risk within the CD population, similar to the general population.
  • CD patients with CAD exhibit a higher prevalence of hyperlipidemia and benefit from early CAD diagnosis in type 1 diabetes cases.
  • Iron deficiency anemia is identified as a statistically significant risk factor for CAD in patients with celiac disease.

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...

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 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...

Coronary Artery Disease II: Pathophysiology

Coronary Artery Disease (CAD) originates from a series of events that impair the function of coronary arteries, the blood vessels responsible for delivering oxygen-rich blood to the heart muscle. The pathophysiology of CAD is closely linked to atherosclerosis, a chronic inflammatory and lipid-driven condition affecting the vascular endothelium.1. Endothelial DamageThe process begins with damage to the vascular endothelium, which serves as a protective barrier between the blood and the vessel...
