EDTA to remove calcium from the body which is responsible for hardening of cholesterol in vessels?

This statement is inaccurate. EDTA (ethylenediaminetetraacetic acid) is not primarily used in the body to remove calcium. Although it has chelating properties and can bind to various minerals, its medical uses are mainly related to anticoagulation and treating heavy metal poisoning. On the other hand, statins or cholesterol-lowering medications effectively reduce cholesterol levels and prevent atherosclerosis, commonly known as the hardening of arteries due to cholesterol build-up.
