Hypothesis

Can high-sensitivity C-reactive protein (hs-CRP) help identify acute coronary syndrome in low-risk chest pain patients?

Conclusion

Measuring hs-CRP did not improve the ability to diagnose acute coronary syndrome in low-risk patients.

Supporting Evidence

  • The study included 918 patients who underwent hs-CRP testing.
  • Acute coronary syndrome was diagnosed in 128 patients (13.4%).
  • The median hs-CRP value was 2.2 mg/l in patients with ACS.

Takeaway

Doctors checked a blood test called hs-CRP to see if it could help find heart problems in patients with chest pain, but it didn't really help.

Methodology

Retrospective study of patients admitted to a chest pain unit who underwent hs-CRP testing.

Potential Biases

Physicians were not blinded to hs-CRP results, which could have influenced treatment decisions.

Limitations

The study was retrospective, and not all patients underwent confirmatory testing, which may have underestimated the incidence of acute coronary syndrome.

Participant Demographics

The cohort included 478 women (52%) and 441 men (48%) with a median age of 56 years.
