When you have heart failure, your heart may not be strong enough to pump out as much blood as your body needs. As it tries to move more blood, your heart gets larger. It also pumps faster, and your blood vessels narrow to get more blood out to your body.
As your heart works harder, it may become weaker. Your body gets less oxygen, and you might notice symptoms like shortness of breath, swelling in your legs, and fluid buildup.
You can't cure heart failure, but you can manage it by following your treatment plan. Medicines, diet, exercise, and surgery are just some of the treatments your doctor might suggest to prevent these problems.
Abnormal Heart Rhythm
In a normal heart, the upper chambers (called the atria) and lower chambers (the ventricles) squeeze and relax in turn to move blood through your body. If your ticker is weak, these chambers might not squeeze at the right time. Your heart might beat too slowly, too quickly, or in an irregular pattern. When the rhythm is off, your heart can't pump enough blood out to your body.
Atrial fibrillation (AFib) is one type of abnormal heart rhythm that heart failure can cause. It causes your heart to quiver and skip instead of beating.
Heart Valve Problems
Your heart has four valves that open and close to keep blood flowing in and out of your heart. As the damage gets worse and your heart has to work harder to pump out blood, it gets bigger. The change in size can damage the valves.
Kidney Damage or Failure
Your kidneys filter waste and extra fluid out of your blood. Just like your other organs, they need a steady supply of blood to work like they should.
Without the amount of blood they need, they won’t be able to remove enough waste from your blood. This can lead to kidney failure. It's treated with dialysis or a kidney transplant.
Kidney disease can also make your heart failure worse. Damaged kidneys can't remove as much water from your blood as healthy ones. You'll start to hold onto fluid, which boosts your blood pressure. High blood pressure makes your heart work even harder.
This is a lack of the red blood cells that move oxygen to your body's tissues. If you have anemia, your body may not get enough oxygen. Your kidneys make a protein called erythropoietin (EPO), which helps your body make new red blood cells. Kidney damage from heart failure prevents your body from making enough EPO.
Your liver breaks down toxins so your body can remove them. It also stores bile, a fluid used to digest food.
Heart failure can rob your liver of the blood it needs to work. The fluid buildup that comes with it puts extra pressure on the portal vein, which brings blood to your liver. This can scar the organ to the point where it doesn't work as well as it should.
A damaged heart can't pump blood as effectively from your lungs out to your body. Blood backs up, raising pressure in the veins inside your lungs. This pushes fluid into your air sacs. As liquid builds up, it gets harder to breathe. This is called pulmonary edema.
Extreme Weight Loss and Muscle Loss
How to Prevent Complications
Heart failure may get worse over time if you don't treat it. Severe heart failure can be life threatening.
Treatments like weight loss, a healthy diet, exercise, and medicines can protect your heart and keep you healthy. Follow your doctor's advice and stick with your treatment plan. The better you take care of your heart, the less likely you are to have other problems.
