Heart Failure
Heart failure, sometimes known as Congestive Heart Failure (CHF), occurs when the heart can't pump enough to the rest of the body. If the heart muscle cannot pump enough blood, it cannot meet the body's needs for blood and oxygen. The heart is a pump that circulates the blood throughout the body.
Varicose Veins
Varicose veins are dilated veins that have lost their valve effectiveness and become elongated, bulged and thickened. Veins carry blood from the capillaries to the heart. In the leg, this means the blood has to flow upward, against gravity. These veins have one-way valves to prevent the blood from flowing backwards.
