Coronary Atherosclerosis Disease Early Identification and Risk Stratification by Noninvasive Imaging

Coronary Atherosclerosis Disease Early Identification and Risk Stratification by Noninvasive Imaging :A Cohort Study of China

The investigator prospectively enroll 30,000 outpatients who were suspected of coronary artery disease (CAD) and underwent cardiac computed tomography angiography (CTA). The endpoint was major adverse cardiac events (MACE).The investigator aim to evaluate the prognostic value of CTA, risk factors and bio-markers for MACE.

The investigator prospectively enroll 30,000 outpatients who were suspected of coronary artery disease (CAD) and underwent cardiac computed tomography (CT). Cardiac CT was assessed for coronary artery calcification score (CACS) and the extent, the location, the stenosis severity, and the composition of the plaque in CTA. The base line information was recorded, including risk factors, drugs, bio-markers, and psychological. The endpoint was MACE, defined as composite cardiac death, nonfatal myocardial infarction (MI).we aim to evaluate the prognostic value of CTA, risk factors and bio-markers for major adverse cardiac events (MACE).

Inclusion Criteria:

1. suspected of coronary heart disease, coronary CTA has been completed.
2. age > 18 years old.
3. have biochemical test results.
4. signed informed consent.

Exclusion Criteria:

1. malignant tumor, severe liver and kidney diseases.
2. combination of cardiomyopathy, valvular disease, congenital heart disease, a variety of reasons the left cardiac insufficiency.
