How can the nurse best describe heart failure to a client?

The best description of heart failure is that it is characterized by the inability of the heart to pump blood in proportion to the body's metabolic needs. This means that the heart is unable to effectively circulate blood to meet the demands of the body's tissues, leading to a host of symptoms and complications.

Heart failure can result from various underlying conditions that weaken the heart muscle or affect its ability to fill with blood. For example, conditions such as ischemic heart disease or hypertension can lead to a reduced ejection fraction, impacting the heart's functionality. Consequently, patients may experience fatigue, shortness of breath, and fluid build-up, as their bodies do not receive sufficient oxygen and nutrients.

Understanding this definition is crucial for patients as it highlights the overall impact of heart failure on their health and daily life. It emphasizes that heart failure is not just about blood pressure or volume but rather about the heart's ability to maintain adequate circulation to meet the body's requirements.
