A clinical condition in which the function of the heart is inadequate to meet the metabolic needs of the body.

A heterogeneous condition in which the heart is unable to pump out sufficient blood to meet the metabolic need of the body. Heart failure can be caused by structural defects, functional abnormalities (VENTRICULAR DYSFUNCTION), or a sudden overload beyond its capacity. Chronic heart failure is more common than acute heart failure which results from sudden insult to cardiac function, such as MYOCARDIAL INFARCTION.

Heart failure means that your heart can't pump enough oxygen-rich blood to meet your body's needs. Heart failure doesn't mean that your heart has stopped or is about to stop beating. But without enough blood flow, your organs may not work well, which can cause serious problems. Heart failure can affect one or both sides of your heart: With right-sided heart failure, your heart is too weak to pump enough blood to your lungs to get oxygen.; With left-sided heart failure, your heart can't pump enough oxygen-rich blood out to your body. This happens when the left side of your heart becomes either: Too weak to pump enough blood.; Too thick or stiff to relax and fill with enough blood. . Left-sided heart failure is more common than right-sided heart failure. Heart failure can start suddenly after a medical condition or injury damages your heart muscle. But in most cases, heart failure develops slowly from long-term medical conditions. Conditions that can cause heart failure include: Arrhythmia (a problem with the rate or rhythm of your heartbeat); Cardiomyopathy; Congenital heart defects or other types of heart diseases that you are born with; Coronary artery disease; Endocarditis; Heart attack; Heart valve diseases; High blood pressure; A blood clot in your lung; Diabetes; Certain severe lung diseases, such as COPD (chronic obstructive pulmonary disease); Obesity. Over time, left-sided heart failure can lead to right-sided heart failure. Heart failure can happen at any age. It happens to both men and women, but men often develop it at a younger age than women. Your chance of developing heart failure increases if: You're 65 years old or older. Aging can weaken and stiffen your heart muscle.; Your family health history includes relatives who have or have had heart failure.; You have changes in your genes that affect your heart tissue.; You have habits that can harm your heart, including: Smoking; Eating foods high in fat, cholesterol, and sodium (salt); Having an inactive lifestyle; Alcohol use disorder (AUD); Illegal drug use.; You have other medical conditions that can affect your heart, including: Any heart or blood vessel conditions, including high blood pressure; Serious lung diseases; Infection, such as HIV or COVID-19; Obesity; Diabetes; Sleep apnea; Chronic kidney disease; Anemia; Iron overload disease; Cancer treatments that can harm your heart, such as radiation and chemotherapy.; You are African American. African Americans are more likely to develop heart failure and have more serious cases at younger ages than people of other races. Factors such as stigma, discrimination, income, education, and geographic...

Inability of the heart to meet tissue metabolic requirements.

Inability of the heart to pump blood at an adequate rate to meet tissue metabolic requirements. Clinical symptoms of heart failure include: unusual dyspnea on light exertion, recurrent dyspnea occurring in the supine position, fluid retention or rales, jugular venous distension, pulmonary edema on physical exam, or pulmonary edema on chest x-ray presumed to be cardiac dysfunction.

The inability of the heart to pump enough blood to meet the needs of the body's organs.

A disorder characterized by the inability of the heart to pump blood at an adequate volume to meet tissue metabolic requirements, or, the ability to do so only at an elevation in the filling pressure.

Heart failure (HF) is a syndrome of ventricular dysfunction. Left ventricular failure causes shortness of breath and fatigue, and right ventricular failure causes peripheral and abdominal fluid accumulation; the ventricles can be involved together or separately. Diagnosis is initially clinical, supported by chest x-ray, echocardiography,...

Heart failure develops when the heart, via an abnormality of cardiac function (detectable or not), fails to pump blood at a rate commensurate with the requirements of the metabolizing tissues or is able to do so only with an elevated diastolic filling pressure. See the image below.

Heart failure, sometimes known as congestive heart failure, occurs when your heart muscle doesn't pump blood as well as it should. Certain conditions, such as narrowed arteries in your heart (coronary artery disease) or high blood pressure, gradually leave your heart too weak or stiff to fill and pump efficiently.

Heart failure, general condition in which the heart muscle does not contract and relax effectively, thereby reducing the performance of the heart as a pump and compromising blood circulation throughout the body. Heart failure is a major public health concern in countries worldwide. Although...
