Association of Autoimmune Diseases With Coronary Atherosclerosis Severity and Ischemic Events
Authors' conclusion
Autoimmune diseases were independently associated with higher burden of coronary atherosclerosis and higher risk for future ASCVD events, with risk accentuated by traditional cardiovascular risk factors.
Study context
- Population
- Patients undergoing coronary CT angiography, Western Denmark Heart Registry3,832 atherosclerotic cardiovascular disease (ASCVD) events
- Participants
- 85,512 patients
- Exposure
- Autoimmune disease vs no autoimmune disease
- Autoimmune diseasen = 4,064
- Outcome
- Coronary atherosclerosis (any plaque, any coronary artery calcification (CAC), CAC >90th percentile, obstructive CAD) and ASCVD events
- Follow-up
- 5.3 years (Q1-Q3: 2.8-8.2 years)
Main finding

ASCVD
aHR 1.46(1.29–1.65)
Observational data: associations, not effects.

ASCVD in autoimmune patients, by cardiovascular risk factor profile
- Traditional cardiovascular risk factors strongly associated with future ASCVD events
