Final answer:
In right-heart failure, symptoms such as edema in the extremities occur due to increased pressure in the vena cavae, while chest pain, rapid heartbeat, and hypertension are more closely associated with left-heart failure, which can result in pulmonary edema.
Step-by-step explanation:
The right side of the heart is responsible for pumping blood through the lungs, where it picks up oxygen. When the right side of the heart cannot pump blood normally, it can lead to right-heart failure. This condition typically results in a rise in pressure in the vena cavae, causing fluid to back up leading to symptoms such as edema in the extremities. However, chest pain, rapid heartbeat, and hypertension are typically associated with issues in the left side of the heart, which can lead to pulmonary edema and increased pressure in the pulmonary capillaries.
In right-heart failure, the inability to pump blood effectively into the lungs can cause a drop in pressure in the arteries to the lungs, while left-heart failure is characterized by a rise in pressure entering the left side of the heart and a drop in aortal pressure. Both conditions can have severe consequences for the circulation of blood and the functioning of various organs in the body.
