Usefulness of Reynolds Risk Score in men with stable angina

Introduction

Recently several risk scores have been proposed that, beyond traditional risk factors, also include additional inflammatory biomarkers underlying atherothrombosis. The Reynolds Risk Score (RRS) is a point scale assessing the risk of cardiovascular events over 10 years, which takes into account for the first time high-sensitivity C-reactive protein. The aim of this study was to establish clinical usefulness of RRS in men with stable coronary artery disease and preserved left ventricular systolic function.

Material and Methods

In total, 119 symptomatic non-diabetic man (mean age 63.9±9.23) who were directed for an elective coronary arteriography were enrolled in the study. Clinical data were collected including the elevated heart rate ≥70 bpm/min, basic laboratory results, placental growth factor and results of coronary angiography. Patients were analyzed related to RRS: low risk <10% (n=50), moderate risk 10-19% (n=46) and high risk >20% (n=23).

Results

Opposite to high RRS patients, in the low risk group more often occurred marginal or none atherosclerotic coronary arteries (13% vs. 44%, P=0.0214). The findings have revealed the relationship between the higher risk score and the lower frequency of marginal or no atherosclerotic coronary arteries (OR=0.19, 95%CI 0.05–0.67).

Conclusions

The Reynolds Risk Score appears to be useful in men with stable coronary artery disease and preserved left ventricular systolic function in stratifying the severity of coronary atherosclerosis.
