Question: 1 / 400

What is a common characteristic of heart failure?

Increased ability to exercise

Improved oxygen levels in the blood

Fluid buildup in the lungs

A common characteristic of heart failure is fluid buildup in the lungs, also known as pulmonary congestion. In heart failure, the heart's ability to pump blood effectively is compromised, which can lead to a backlog of blood in the veins. This backlog increases pressure in the pulmonary blood vessels, causing fluid to leak into the lung tissues and airways. As a result, individuals may experience shortness of breath, especially with exertion or when lying down, due to the accumulation of fluid in the lungs. This symptom can be a critical indicator of worsening heart failure and is often monitored closely in individuals diagnosed with this condition.
