Diagnosis of Atherosclerosis
Angiography and stress testing are used to detect atherosclerosis but they can detect only severe obstruction.
Certain anatomic and physiologic methods are used to detect the disease before it becomes symptomatic. Anatomic methods include coronary calcium scoring by CT, carotid intimal media thickness measurement by ultrasound, and intravascular ultrasound. Physiologic methods include lipoprotein analysis, HbA1c, and homocysteine testing. These approaches have not proved to be very useful by clinicians.
