Abstract
Background
High sensitivity C-reactive protein (hs-CRP) is commonly used in clinical practice
to assess cardiovascular risk. However, a correlation has not yet been established
between the absolute levels of peripheral and central hs-CRP.
Objective
To assess the correlation between serum hs-CRP levels (mg/L) in a peripheral vein
in the left forearm (LFPV) with those in the coronary sinus (CS) of patients with
coronary artery disease (CAD) and a diagnosis of stable angina (SA) or unstable
angina (UA).
Methods
This observational, descriptive, and cross-sectional study was conducted at the
Instituto do Coração, Hospital das Clinicas, Faculdade de Medicina, Universidade
de São Paulo, and at the Hospital Beneficência Portuguesa de Sao Paulo, where CAD
patients referred to the hospital for coronary angiography were evaluated.
Results
Forty patients with CAD (20 with SA and 20 with UA) were included in the study.
Blood samples from LFPV and CS were collected before coronary angiography.
Furthermore, analysis of the correlation between serum levels of hs-CRP in LFPV
versus CS showed a strong linear correlation for both SA (r = 0.993, p < 0.001)
and UA (r = 0.976, p < 0.001) and for the entire sample (r = 0.985, p <
0.001).
Conclusion
Our data suggest a strong linear correlation between hs-CRP levels in LFPV versus
CS in patients with SA and UA.
