Abstract
Aims: Adding intensive low-density lipoprotein cholesterol (LDL-C)-lowering agents or colchicine to statin has been shown to result in additional cardiovascular benefits for patients with atherosclerotic cardiovascular diseases (ASCVD). We aimed to compare the efficacy and safety of these supplementary agents in patients with ASCVD receiving statin.
Methods: We performed a systematic review and frequentist network meta-analysis of randomized controlled trials. The primary efficacy endpoint was the main adverse cardiovascular event (MACE), and the secondary efficacy endpoints were myocardial infarct, stroke, coronary revascularization, cardiovascular death, and all-cause mortality, respectively. The safety endpoints were treatment discontinuation and non-cardiovascular death. We obtained estimates for efficacy outcomes and safety endpoints and presented these estimates as risk ratio (RR) with 95% confidence intervals. We ranked the comparative efficacy and safety of all drugs with P-scores.
Results: Seventeen trials totaling 85,823 participants treated with colchicine (5926 participants), intensive LDL-C lowering (37,854 participants) via proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitor, Niemann-Pick C1-like 1 protein (NPC1L1) inhibitor or ATP citrate lyase (ACL) inhibitor, or statin alone (42,043 participants) were included. Colchicine was associated with a greater reduction in the risk of MACE (RR 0.72, 0.69-0.91), stroke (RR 0.55, 0.33-0.92), and coronary revascularization (RR 0.73, 0.60-0.90) compared with NPC1L1 inhibitor, and it provided a larger reduction in the risk of MACE (RR 0.79, 0.69-0.91) compared to PCSK9 inhibitor. However, colchicine was associated with increased risk of non-cardiovascular death compared with NPC1L1 inhibitor (RR 1.48, 1.04-2.10) and PCSK9 inhibitor (RR 1.57, 1.08-2.27). Although no regimen prolonged survival, colchicine had worse performance on non-cardiovascular death and all-cause mortality.
Conclusions: In patients with ASCVD receiving statin, colchicine seems to be more effective than intensive LDL-C-lowering therapy with PCSK9 inhibitor or NPC1L1 inhibitor for cardiovascular prevention. However, using colchicine as an alternative to intensive LDL-C-lowering therapy may need to be weighed against the cardiovascular benefits and the potential harms of higher non-cardiovascular death.
