Complications

Complications of heart failure depend on the severity of heart disease, your overall health and other factors such as your age. Possible complications can include:

• Kidney damage or failure. Heart failure can reduce the blood flow to your kidneys, which can eventually cause kidney failure if left untreated. Kidney damage from heart failure can require dialysis for treatment.
• Heart valve problems. The valves of the heart, which keep blood flowing in the right direction, may not work properly if your heart is enlarged or if the pressure in your heart is very high due to heart failure.
• Heart rhythm problems. Heart rhythm problems may lead to or increase your risk of heart failure.
• Liver damage. Heart failure can cause fluid buildup that puts too much pressure on the liver. This fluid backup can lead to scarring, which makes it more difficult for your liver to work properly.
