Plaque Vulnerability and Cardiovascular Risk Factor Burden in Acute Coronary Syndrome

J Am Coll CardiolPublished

  • Cross-sectional study

Authors' conclusion

In patients with ACS, an increasing number of cardiovascular risk factors were strongly associated with greater plaque vulnerability, especially for culprit lesions.

Study context

Population
Patients with acute coronary syndrome (ACS); plaques assessed by optical coherence tomography2,187 plaques analysed
Exposure
≥2 vs 0-1 traditional risk factors
Outcome
Plaque vulnerability defined by optical coherence tomography

Main finding

As reported in the abstract

Vulnerable features in culprit plaques by number of risk factors
Lipid-rich plaques increased with number of risk factors
P trend = 0.027
Thin-cap fibroatheromas increased
P trend = 0.006
Macrophages increased
P trend <0.001
Microvessels increased
P trend <0.001
Cholesterol crystals increased
P trend = 0.032
Plaque rupture increased
P trend = 0.015
Plaque erosion decreased
P trend <0.001

Observational data: associations, not effects.

Further findings

Nonculprit plaques (606)

Only macrophages, cholesterol crystals and cumulative number of vulnerable features per plaque significantly positively associated with number of risk factors
