Swelling or puffiness of the tissue around the legs and ankle region (medically known as edema) is a common sign of heart disease.
If the right muscle of the heart is weakened, the amount of blood pumped out also could be diminished leading to edema in the abdomen region or legs due to the buildup of pressure behind the right side of the heart (note: if the left side of the heart is weakened pressure builds up in the pulmonary veins and eventually the lungs possibly leading to dyspnea (shortness of breath) but not edema.
Ankle swelling that is seen after periods of prolonged standing or sitting could indicate salt and water retention possibly due to right-sided heart failure.
In people with sedentary lifestyle and those who do not get enough exercise in the day, blood is retained in the lower part of the legs and is not efficiently returned to the heart, which could also lead to development of heart disease over a period of time.
