Yes, cirrhosis is the last stage of liver failure (after "fibrosis").
It is not reversible. Cirrhosis is the final stage of liver failure, in which the hepatocytes (liver cells) have reached a stage of scarring which renders them unable to regenerate healthy, new cells. The treatment for cirrhosis, aside from drugs to relieve symptoms, is a transplant.
Cirrhosis is not a disease in itself, it is a stage of liver failure (the final stage, in fact). Whether it is "communicable" or not depends on whether the cause of the cirrhosis is communicable.
Cirrhosis is the final stage of liver failure, in which the liver has been scarred to the extent that it's capacity to regenerate has diminished/vanished. It is not reversible.
When a doctor says that you are in the 4th stage of cirrhosis, he means that you are in the worst and generally final stage of the disease. Without treatment, this stage generally will end in liver failure and death.
Early symptoms of liver failure include jaundice, nausea, vomiting, tiredness, difficulty concentrating, and confusion. These symptoms may be accompanied by pain in the upper right area of the abdomen.
End stage liver failure is also known as cirrhosis. The patient would have fluid and may look pregnant, they could be jaundiced, and experience no pain or quite a bit of pain. The person could be very weak and lead to coma and death.
Liver failure in dogs is diagnosed through a complete blood workup. Liver failure is a serious condition that requires you to work closely with your dog's veterinarian.
Liver failure is a serious chronic medical condition which requires treatment. Liver failure signs and symptoms include ascites (swelling of the abdomen), gastrointestinal bleeding, encephalopathy, and dilation of blood vessels on the abdomen. Untreated liver failure may be fatal.
Liver cirrhosis is progressive scarring of the hepatocytes (liver cells), leading to loss of liver function. Cirrhosis is not a disease in itself- it is the term used for when a liver has become scarred beyond repair, due to any cause (whether viral, auto-immune, alcohol etc...). I.e it is the stage before "complete liver failure".
To much alcohol can cause liver failure.
A heart attack itself will not directly damage your liver unless it's related to long term heart failure. If you have right-side heart failure, your liver will not be affected. If you have left-side heart failure your liver may become enlarged.
