Early Symptoms and Signs of Heart Failure
Early Symptoms and Signs of Heart Failure Overview
Heart failure is a condition whereby the heart muscle is unable to adequately pump blood throughout the body. There are a variety of illnesses and diseases that affect the heart's pumping capability. Heart failure causes signs and symptoms due to the excess accumulation of fluid within the tissues of the body.
Circulation is a continuous loop whereby the left side of the heart pumps oxygen-rich blood to the body. The right side of the heart pumps blood containing carbon dioxide to the lungs.
Blood consists of red blood cells, white blood cells, platelets, and plasma. While plasma contains proteins, vitamins, minerals, hormones, and a variety of other chemicals, it is more than 90% water.
When the heart muscle becomes weak and cannot adequately pump into the arteries, blood “backs up” and pressure in the blood vessels causes water to leak out of blood vessels into the tissues of the body.
Right Heart Failure Symptoms
When the right ventricle cannot pump blood adequately, blood backs up into the veins that return blood to the right heart. Fluid then leaks out of veins and capillaries.
