Cholesterol is just one of the fats that could be involved in the “clogging” of blood vessels.
Cholesterol contributes to the formation of fatty plaques that “attach” themselves to the smooth inner lining of blood vessels.
Continuous attachment of fat to the smooth inner lining of the blood vessels may lead to a reduction in the diameter of the blood vessels. The heart then has to work harder to pump the blood through the smaller openings. This may lead to high blood pressure, heart disease and stroke.
Sometimes a fatty plaque actually blocks the small blood vessels that transport blood and nutrients to the heart muscle. The result of this is that some areas of the heart muscle do not receive adequate oxygen or nutrient supply and this may lead to a heart muscle malfunction.
Sometimes a piece of these fatty plaques could dislodge and this could cause a blockage in the blood vessels responsible for transporting blood to the heart, resulting in an instant heart attack.
