amyloidosis, in which deposits of proteins accumulate in one or more organ systems.

hemochromatosis, a condition in which iron accumulates in the tissues.

atrial fibrillation, an irregular and often rapid heartbeat.

heart arrhythmias, or irregularities - a fast heartbeat can weaken the heart, and a slow heartbeat can reduce blood flow, causing heart failure.

myocarditis, which is inflammation of the heart muscle that usually occurs due to a virus and can lead to left-sided heart failure.

thyroid problems, including hyperthyroidism and hypothyroidism.

The following are risk factors for congestive heart failure:

Conditions that overwork the heart: Examples include valve disease, high blood pressure, diabetes, kidney disease, sleep apnea, and heart irregularities present at birth.

Possible causes include genetic conditions, drug side effects, and infections.

Nonischemic cardiomyopathy: This disease involves weakness of the heart muscle caused by something other than a blockage in the coronary arteries.

The damage may also result from an increased demand for blood flow due to a fixed blockage. It can result from a sudden blockage of the coronary arteries that causes scarring and reduces how effectively the heart can pump.

Heart attack: This involves damage to the heart muscle.

If these become blocked or narrowed, the flow of blood diminishes, and the heart does not receive the blood supply that it needs.

Coronary artery disease: The coronary arteries supply the heart muscle with blood.

This article focuses on systolic congestive heart failure, and we cover its causes, symptoms, types, and treatment.Īny condition that damages the heart muscle can cause systolic heart failure.

The condition can be systolic or diastolic, depending on whether it affects the heart’s ability to contract or relax. There is usually no cure for heart failure, but with the right treatment, people can often lead enjoyable and productive lives.Īccording to the Centers for Disease Control and Prevention (CDC), more than 6 million adults in the United States have heart failure. Everyday activities that used to be easy may become challenging. If the heart becomes weakened and cannot supply the cells with sufficient blood, it can lead to fatigue and breathlessness.

When the cells do not receive adequate nourishment, the body cannot function properly. The body relies on the pumping action of the heart to deliver nutrient- and oxygen-rich blood to each of its cells.

However, heart failure is a serious condition, in which the heart does not pump blood around the body efficiently. Watch an interactive animation of heart failure.Despite its name, congestive heart failure does not necessarily mean that the heart has stopped working. The larger the heart becomes, the harder it works to meet your body's demands for oxygen and nutrients. While it's still able to pump blood, it becomes less efficient. Over time, a higher workload leads to an enlarged heart: To cope with increased demands, the heart thickens and becomes larger.High blood pressure adds to your heart’s workload: Narrowed arteries that are less elastic make it more difficult for blood to travel efficiently throughout your body.The thickening and/or stiffening of the heart’s walls, as well as narrowing and constriction of blood vessels caused by high blood pressure, are the most common non-cardiac causes of heart failure. Heart failure, a condition in which your heart is unable to provide enough blood to the body, can happen quickly or take years to develop. Is there a link between HBP and heart failure?
