  Purpose

Disruption of an atherosclerotic plaque is responsible for at least two-thirds of acute coronary syndrome. Thus, identification of plaques vulnerable to rupture has become important. The natural history of individual plaques is unknown and needs to be established. Multidetector computed tomography (MDCT) angiography is a useful noninvasive imaging modality for assessing coronary plaque characteristics. Using MDCT, the researchers prospectively investigate the relationship between the characterization of coronary plaques and cardiovascular events in a large multicenter study.

Further study details as provided by Hiroshima University:

Primary Outcome Measures:
  • Major cardiac events (Cardiac death and acute coronary syndrome) [ Time Frame: 2 years after the CT-scan ] [ Designated as safety issue: No ]
  • All-cause death [ Time Frame: 2 years after the CT-scan ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • All coronary events (Cardiac death, non-fatal MI, unstable angina requiring hospitalization, late coronary revascularizations) [ Time Frame: 2 years after CT-scan ] [ Designated as safety issue: No ]
  • All cardiovascular events (Death, acute coronary syndrome, heart failure, cerebral disease, peripheral artery disease, aortic disease, and renal failure) [ Time Frame: 2 years after the CT-scan ] [ Designated as safety issue: No ]

Other Outcome Measures:
  • Coronary plaque progression and managements for serum cholesterol, blood glucose, renal function and blood pressure: Especially impacts of statin on the changes in coronary plaque characteristics [ Time Frame: 2 years after CT ] [ Designated as safety issue: No ]
