Clinical Information
- 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.
- 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.
- Complication of heart diseases; defective cardiac filling and/or impaired contraction and emptying, resulting in the heart’s inability to pump a sufficient amount of blood to meet the needs of the body tissues or to be able to do so only with an elevated filling pressure.
- Failure of the heart to pump a sufficient amount of blood to meet the needs of the body tissues, resulting in tissue congestion and edema. Signs and symptoms include shortness of breath, pitting edema, enlarged tender liver, engorged neck veins, and pulmonary rales.
- Heart failure accompanied by edema, such as swelling of the legs and ankles and congestion in the lungs.
- Heart failure is a condition in which the heart can’t pump enough blood throughout the body. Heart failure does not mean that your heart has stopped or is about to stop working. It means that your heart is not able to pump blood the way it should. The weakening of the heart’s pumping ability causes
- blood and fluid to back up into the lungs
- the buildup of fluid in the feet, ankles and legs – called edema
- tiredness and shortness of breath
- Inability of the heart to pump blood at an adequate rate to fill tissue metabolic requirements or the ability to do so only at an elevated filling pressure.
- Inability of the heart to pump blood at an adequate rate to meet tissue metabolic requirements or the ability to do so only at an elevated filling pressure.
- 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.
- Weakness of the heart muscle that leads to a buildup of fluid in body tissues.
