Liver: an alarm for the heart?

Area of Science:

• Cardiology
• Hepatology
• Metabolic Syndrome

Background:

• Fatty liver and coronary artery disease share common risk factors.
• Their frequent coexistence is often attributed to these shared risk factors.
• This study investigates the independent association between fatty liver and coronary artery disease.

Purpose of the Study:

• To assess the independent association between fatty liver and angiographic coronary artery disease.
• To determine if fatty liver is an independent predictor of coronary artery disease, beyond shared risk factors.

Main Methods:

• A case-control study involving 317 adult patients undergoing coronary angiography.
• Patients were divided into two groups: normal/mildly abnormal coronary angiography (n=85) and clinically relevant coronary artery disease (n=232).
• Liver sonography was performed on the same day as coronary angiography.

Main Results:

• Significant differences were observed between groups in gender, fasting blood glucose, LDL, diabetes, hypertension, and fatty liver.
• Fatty liver emerged as the strongest independent predictor of coronary artery disease (OR=8.48, P<0.001).
• Diabetes (OR=2.94, P=0.002) and male gender (OR=2.31, P=0.014) were also independent predictors.

Conclusions:

• Fatty liver is a significant independent predictor of coronary artery disease.
• Fatty liver serves as a crucial alarm for the presence of significant coronary artery disease.
• These findings emphasize the importance of considering fatty liver in cardiovascular risk assessment.
