Insights
Coronary artery disease (CAD) is more common in liver cirrhosis patients than the general population. Older age and alcoholic cirrhosis are key risk factors in these patients.
Area of Science:
- Cardiology
- Hepatology
- Internal Medicine
Background:
- Previous studies suggested a low prevalence of coronary artery disease (CAD) in liver cirrhosis patients, primarily focusing on hepatitis C etiology.
- This study investigates CAD prevalence and predictive factors in a diverse cohort of liver cirrhosis patients compared to the general population.
Purpose of the Study:
- To determine the prevalence of coronary artery disease (CAD) in patients with liver cirrhosis of various etiologies.
- To identify predictive factors for CAD in liver cirrhosis patients.
- To compare CAD prevalence between liver cirrhosis patients and a control group from the general population.
Main Methods:
- 127 liver cirrhosis patients were assessed for CAD history and cardiovascular risk factors, including blood pressure, glucose, and cholesterol levels.
- Nutritional status was evaluated using anthropometry and recent weight change.
- A control group of 203 individuals from the general population with similar demographics and smoking habits was included for comparison.
Main Results:
- Coronary artery disease (CAD) was more prevalent in liver cirrhosis patients (20%) compared to controls (12%).
- Cirrhotic patients exhibited lower mean arterial blood pressure and serum cholesterol but a higher prevalence of diabetes.
- In regression analysis, diabetes was independently associated with CAD, while liver cirrhosis itself was not a significant predictor. In the cirrhosis group, older age and alcoholic etiology were independently related to CAD.
Conclusions:
- Liver cirrhosis does not appear to offer protection against coronary artery disease (CAD).
- In patients with liver cirrhosis, older age and alcoholic etiology are significant independent predictors of CAD.
- Diabetes is a key independent risk factor for CAD in patients with liver cirrhosis.
Background:
The prevalence of coronary artery disease (CAD) has been reported to be low in patients with liver cirrhosis. Previous studies have, however, included mostly patients with cirrhosis due to hepatitis C. We aimed to determine the prevalence and predictive factors of CAD in a cohort of consecutive patients with cirrhosis of various etiologies compared to the general population.
Methods:
A total of 127 patients with cirrhosis were evaluated for a history of CAD and cardiovascular risk factors. Arterial blood pressure, fasting plasma glucose, and serum cholesterol were measured. Nutritional status was assessed by anthropometry and estimation of recent weight change. A group of 203 subjects from the general population with similar age and gender distribution, as well as smoking habits as the cirrhotic patients, served as controls.
Results:
CAD was more common in cirrhotics compared to controls (20% vs. 12%, P = 0.001). Compared to controls, cirrhotics had lower mean arterial blood pressure and serum cholesterol and a higher prevalence of diabetes, but did not differ significantly in the prevalence of hypertension or family history for CAD. In regression analysis, CAD was independently related to diabetes (odds ratio [OR] 5.47, 95% confidence interval [CI] 2.44-12.28), but not to liver cirrhosis. In the cirrhosis group, only alcoholic cirrhosis (OR 9.50, 95% CI 1.08-83.4) and age (OR 1.23 per year, 95% CI 1.06-1.43) were independently related to CAD.
Conclusions:
Liver cirrhosis, per se, does not seem to confer a protective effect against CAD. In cirrhotics, older age and alcoholic etiology were independently related to CAD.

Cirrhosis is characterized by the scarring of hepatic lobules in the liver, which are replaced by fibrous tissue, affecting the liver's normal functioning. NAFLD, on the other hand, is caused by an excessive build-up of fat in the liver, not related to...
