In patients with liver cirrhosis and those in whom liver transplant is planned, after the decompensated form of the disease is stabilized, cardiac troponins (cTnI and cTnT) and NT-proBNP concentrations can identify the patients who have developed cirrhotic cardiomyopathy or who are at an increased risk of the disease. This evidence concerns the gene TNNI3 and cirrhosis of liver.
