Why Heart Testing is important?
A high amount of cholesterol in the body can build up in the walls of your arteries, which causes a condition known as atherosclerosis, which is a kind of heart disease. In this condition, the arteries are narrowed because of plaque buildup and thus the flow of blood is reduced to various organs and tissues. Atherosclerosis can also lead to coronary artery disease, wherein the blood supply to the heart is impaired due to a blockage in the coronary arteries. This can cause a heart attack.
There are different types of Heart Tests available that can help in diagnosing if your heart is working well. A Serum Cholesterol Test is one type of Heart Test that an individual can get done. A Lipid Test includes a Cholesterol Test along with HDL, LDL, VLDL and ratios between the types of cholesterol.
A Lipid Profile Test is recommended to assess for risks of heart disease, especially if you are at higher risk because of family history, age or other contributing factors like obesity, high blood pressure etc. HbA1c Test is an effective screening test that can help you assess your condition and then work towards correcting it.
