Final answer:
A patient diagnosed with heart failure with normal ejection fraction is most likely characterized by a symptom called heart failure with preserved ejection fraction (HFpEF). This condition is associated with stiff heart muscles, making it difficult for the heart to fill with blood during relaxation. Despite this, the ejection fraction remains within the normal range.
Step-by-step explanation:
A patient diagnosed with heart failure with normal ejection fraction is most likely characterized by a symptom called heart failure with preserved ejection fraction (HFpEF). In this condition, the heart muscles are stiff, making it difficult for the heart to fill with blood during relaxation (diastole). Despite this, the ejection fraction, which measures the percentage of blood pumped out of the heart with each contraction, remains within the normal range (approximately 55-70 percent).
The normal ejection fraction indicates that the heart is still able to pump out a sufficient amount of blood, although it may have to work harder due to the stiffness of the heart muscles. HFpEF is commonly associated with conditions such as hypertension, diabetes, and age-related changes in the heart.
Managing HFpEF involves treating the underlying conditions, controlling blood pressure, and improving lifestyle factors like diet and exercise. Medications may also be prescribed to alleviate symptoms and improve heart function.
