Introduction: Heart failure
Heart failure describes when the heart is having difficulty completing its work.
The term is not the same as heart attack or cardiac arrest, when the
heart may stop;
heart failure involves a gradual failing of the heart.
Heart failure: Heart failure occurs when the heart loses its ability to pump enough blood through the body. Usually, the loss in pumping action is a symptom of an underlying heart problem, such as coronary artery disease.
The term heart failure suggests a sudden and complete stop of heart activity. But, actually, the heart does not suddenly stop. Rather, heart failure usually develops slowly, often over years, as the heart gradually loses its pumping ability and works less efficiently. Some people may not become aware of their condition until symptoms appear years after their heart began its decline. 1
Researching symptoms of Heart failure: Further information about the symptoms of Heart failure is available including a list of symptoms of Heart failure, other diseases that might have similar symptoms in differential diagnosis of Heart failure, or alternatively return to research other symptoms in the symptom center.
Misdiagnosis and Heart failure: Research more detailed information about misdiagnosis of Heart failure, failure to diagnose Heart failure, underlying causes of Heart failure (possibly misdiagnosed), or research misdiagnosis of other diseases
