    Yeah, edema (fluid gathering, causing swelling) is a classic sign of diastolic heart failure. It’s caused by the muscle fibers of the heart stiffening, which reduces the heart’s ability to expand and draw fresh blood in between beats. Usually caused by a lack of exercise. The heart can’t draw blood back up from the legs, which increases blood pressure in the legs as blood gets pumped down but not back up. This extra pressure in the legs forces fluid out of the veins and into the surrounding tissues, causing swelling.
