Direct answer

Congestive hepatopathy is hepatic injury from raised pressure in the hepatic veins, most often from right heart failure or tricuspid regurgitation, producing centrilobular congestion and necrosis known as nutmeg liver. Long-standing congestion can cause perivenular fibrosis, called cardiac cirrhosis, although true cirrhosis is uncommon. Recognising the cardiac cause, a pulsatile liver and high-protein ascites points to the diagnosis, and treatment targets the heart rather than the liver.

What you must remember

Nutmeg liver: centrilobular sinusoidal congestion and hepatocyte necrosis give a red and yellow mottled cut surface.
Mechanism: raised right atrial and central venous pressure is transmitted backwards through the hepatic veins into the sinusoids.
Pulsatile hepatomegaly: significant tricuspid regurgitation transmits systolic pulsation to the enlarged liver, which can be felt as an expansile pulse.
Biochemistry: bilirubin and ALP can rise, with only mild transaminase elevation, which differs from acute hepatocellular necrosis.
Cardiac ascites: a serum-ascites albumin gradient of 1.1 g/dL or more, with total protein above 2.5 g/dL, favours cardiac over portal hypertensive ascites.
Cardiac cirrhosis: long-standing congestion from constrictive pericarditis or tricuspid disease, with pericentral fibrosis that can bridge between central veins.
Bedside clue: a raised jugular venous pressure and a positive hepatojugular reflux support venous congestion.
Management: diuretics for congestion, treatment of the underlying heart disease, and avoidance of over-diuresis, which harms renal perfusion.

Separating cardiac congestion from portal cirrhosis

The two conditions both enlarge the liver and cause ascites, so the bedside features and the ascitic fluid analysis separate them. Each row is a feature that the exam often uses to frame a stem.

Feature	Cardiac congestion	Portal cirrhosis
Jugular venous pressure	Raised	Usually normal
Liver texture	Smooth, enlarged and tender	Firm and nodular in established disease
Liver pulsation	Often present with tricuspid regurgitation	Absent
Ascitic protein	Above 2.5 g/dL	Usually below 2.5 g/dL
Serum-ascites albumin gradient	1.1 g/dL or more	1.1 g/dL or more
Liver biopsy	Centrilobular congestion with the nutmeg pattern	Diffuse fibrosis with regenerative nodules
Key treatment	Optimise the heart failure	Treat portal hypertension and its complications

The serum-ascites albumin gradient is high in both, so it does not separate them on its own. The ascitic protein, the raised venous pressure and the pulsatile liver decide the diagnosis, and a clinician who misreads them may start the wrong treatment. Treatment differs entirely between the two, which is why this distinction is examined so often.

Where the exam tries to catch you

The exam tests whether you recognise a reversible congestive liver and whether you read the ascitic fluid correctly.

Trap: reading a high SAAG as proof of portal hypertension Correct: cardiac ascites also has a high SAAG, so total protein and the jugular venous pressure distinguish it.
Trap: treating only the liver when a patient has congestive ascites Correct: the liver recovers when venous pressure falls, so heart failure must be optimised.
Trap: labelling all hepatomegaly in heart failure as cirrhosis Correct: congestive hepatopathy is often reversible when congestion is controlled, unlike established cirrhosis.

Frequently asked questions

What is a nutmeg liver?

A nutmeg liver is the gross appearance of centrilobular congestion and necrosis from chronic right-sided heart failure, giving a red and yellow mottled cut surface. The pattern reflects blood pooling around the central veins, where oxygen supply is poorest.

How does tricuspid regurgitation cause a pulsatile liver?

Tricuspid regurgitation transmits systolic pressure waves back through the hepatic veins, producing a pulsatile, expansile liver. This finding is typical of significant tricuspid regurgitation and is one of the bedside clues to right heart disease.

Why does cardiac ascites have a high protein content?

Cardiac ascites is protein-rich because congested hepatic sinusoids leak protein-rich lymph into the peritoneal cavity. A total protein above 2.5 g/dL with a high SAAG points to cardiac rather than portal hypertensive ascites.

Does cardiac cirrhosis always progress to true cirrhosis?

Cardiac cirrhosis does not always progress to true cirrhosis, and it is uncommon compared with simple congestion. Pericentral fibrosis can bridge in long-standing cases, so treating the heart disease is the main way to prevent progression.
