What does the term 'heart failure' imply in medical diagnoses?

The term 'heart failure' specifically refers to the inability of the heart to pump effectively, which means that the heart cannot supply enough blood to meet the body's needs. This can result from various underlying conditions, such as coronary artery disease, high blood pressure, or prior heart attacks, all of which can lead to damage or weakening of the heart muscle.

In heart failure, patients may experience symptoms including shortness of breath, fatigue, fluid retention, and a reduced ability to exercise. This condition emphasizes the functional impairment of the heart rather than just the structural issues, which is why this definition is key. Understanding heart failure is critical in managing patients, as it requires a comprehensive approach to treatment, addressing both symptoms and the underlying causes of the heart's decreased pumping ability.
