The Cardio-Hepatic Relation in STEMI.

Area of Science:

• Cardiology
• Hepatology
• Internal Medicine

Background:

• Hepatic injury from congestive heart failure is known, but the effects of acute cardiac dysfunction on the liver are less understood.
• Limited data exist on the impact of acute cardiac dysfunction on liver function.
• This study explores the cardio-hepatic interaction in patients experiencing myocardial infarction.

Purpose of the Study:

• To investigate the relationship between acute cardiac dysfunction and liver injury in ST-elevation myocardial infarction (STEMI) patients.
• To assess the impact of left ventricular ejection fraction (LVEF) and central venous pressure (CVP) on liver enzyme levels.
• To identify potential indicators of a cardio-hepatic syndrome in STEMI patients.

Main Methods:

• A retrospective cohort study of 1339 STEMI patients undergoing primary coronary intervention.
• Echocardiography was used to measure LVEF and CVP, stratifying patients into four groups based on these parameters.
• Liver enzymes (AST, ALT, GGT, ALP) and bilirubin levels were evaluated at baseline and peak.

Main Results:

• A graded increase in liver enzymes (ALT, ALP, GGT) was observed with increasing cardiac dysfunction severity.
• Patients with the worst cardiac function (LVEF < 45% and CVP > 10 mm/Hg) showed significantly higher maximal ALT, ALP, and GGT levels compared to matched controls.
• Propensity score matching confirmed the association between severe cardiac dysfunction and elevated liver enzymes.

Conclusions:

• In STEMI patients, decreased LVEF combined with venous congestion is linked to elevated liver enzymes.
• These findings suggest a potential cardio-hepatic syndrome in the context of acute myocardial infarction.
• The study highlights the importance of monitoring liver function in STEMI patients with impaired cardiac function.
