Adding lipoprotein(a) levels to the GRACE score to predict prognosis in patients with non-ST elevation acute coronary syndrome.

Background: High levels of lipoprotein(a) [Lp(a)] are known to be a cardiovascular risk factor associated with premature coronary artery disease. In predicting the long term prognosis in acute coronary syndromes (ACS), the relationship between Lp(a) and risk scoring systems remains unclear.

Aim: We investigated whether adding Lp(a) to the GRACE scoring system has an incremental value in predicting prognosis in ACS.
