Safety of low lipoprotein(a) levels: the FOURIER trial

Eur Heart JPublished

  • Secondary analysis of the FOURIER randomised trial

Authors' conclusion

In patients with ASCVD, low Lp(a) concentration was not associated with an increased risk of most adverse safety outcomes, but lower Lp(a) was associated with an increased risk of prevalent and incident DM.

Study context

Population
Patients with stable atherosclerotic CVD (atherosclerotic cardiovascular disease (ASCVD)) randomized to evolocumab vs placebo on background statin therapyLp(a) assessed in 25,090
Participants
27,564 patients
Comparison
Lower vs higher baseline Lp concentration
Primary endpoint
Association between Lp(a) and prevalent and incident adverse safety outcomes

Primary result

As reported in the abstract

Lp(a) and adverse safety outcomes
Lower Lp(a) (per 50 nmol/L lower)Estimate (95% CI)P value
prevalent DM at baseline
adjusted OR 1.03(1.02–1.04)
P < 0.001
incident DM during follow-up; consistent by treatment arm
adjusted HR 1.05(1.02–1.08)
P = 0.002

Per 50 nmol/L lower, as printed

Further findings

Outcomeadjusted HR (95% CI)
Incident DM with evolocumab, top decile of baseline Lp(a) (subgroup) · evolocumab reduced Lp(a) by a median of 71 nmol/L.72 (.38-1.35)

Baseline Lp(a)

Median Lp(a), nmol/L (IQR 13-165)
37

Incident diabetes mellitus (DM) with evolocumab, top decile of baseline Lp(a) (subgroup)

Evolocumab did not increase DM risk irrespective of baseline Lp(a)
