In patients admitted to the coronary care unit (CCU), the combination of elevated lipoprotein(a) (Lp[a]) and familial hypercholesterolemia (FH) is associated with increased coronary artery disease (CAD) risk, a recent study found. Plasma Lp(a) concentrations were measured in consecutive patients admitted to the CCU with an acute coronary syndrome (ACS) or prior history of CAD for 6.5 months. Premature CAD was diagnosed in those aged <60 years, with the relationship between this and elevated Lp(a) and FH determined by logistic regression. Among the details:
- 316 patients were screened; 163 (51.6%) had premature CAD.
- Elevated Lp(a) and FH were identified in 27.0% and 11.6% of patients, respectively.
- Both disorders were identified in 4.4% of individuals.
- Elevated Lp(a) and FH phenotype were more common with premature vs nonpremature CAD.
