Abstract:
Calcification is a common finding in human coronary arteries, which is generally associated with long-standing atherosclerosis. However, there is conflicting evidence for the link between calcification and plaque instability. Recent histopathological studies have revealed that plaque calcification is present in 69% of ruptured plaques in sudden coronary death. Furthermore, studies using electron-beam computed tomography have reported that calcium score relates to acute coronary events. Recently, we clarified that in patients with acute myocardial infarction small "spotty" calcifications prevailed, associated with a fibrofatty plaque and positive remodeling. Future studies would focus on the clinical implication of coronary calcification.

Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...
