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.
Abstract:
Background Coronary artery disease (CAD) is associated with celiac disease (CD) with limited evidence. However, the common risk factors linking CD and CAD are still lacking in the literature. Known CAD risk factors include hypertension, hyperlipidemia, type 2 diabetes, obesity, and tobacco use. Common risk factors linking CD and CAD are poorly documented. Objective There are three objectives: Firstly, to evaluate potential demographic differences between CD patients with CAD and without CAD. Secondly, to analyze the risk factors of CAD in CD patients. Lastly, to compare CD-CAD and matched non-CD CAD to determine whether there are additional CAD risks in individuals with CD. Methods The study is a nationwide retrospective case-control study. The National Inpatient Sample (NIS) database was used to identify patients admitted between 2016 and 2018 with a principal or secondary diagnosis of CD. We analyzed sociodemographic and clinical risk factors of CAD in CD patients and compared the CD-CAD population with the matched non-CD CAD cohort. Results Out of 23,441 hospitalizations with CD in 2016-2018, 4244 (18%) were found to have CAD. Established CAD risk factors identified in CD patients included hypertension, hyperlipidemia, type 2 diabetes, and a family history of CAD. In contrast, tobacco use is not a CAD risk factor in CD patients. Female patients with CD had 55% lesser odds of CAD than male patients. The odds of CAD in CD patients with hyperlipidemia were five times higher, 1.2 times higher with essential hypertension, and two times higher with type 2 diabetes. Patients with CAD had a higher prevalence of iron deficiency anemia (9.33% CD-CAD and 8.28% non-CAD CD Vs. 7.32% non-CD CAD). Conclusions Our study confirms that, as with non-CD individuals, males and the White race are at increased CAD risk in the CD population. CD-CAD patients have a higher hyperlipidemia prevalence than non-CD CAD patients. CD patients with type 1 diabetes have an early diagnosis of CAD compared to CD patients with type 2 diabetes. Iron deficiency anemia is a statistically significant risk factor for CAD in CD patients.
