BACKGROUND: Elevated lipoprotein(a) (Lp[a]) levels are an independent risk factor for the development of atherosclerotic diseases, including peripheral artery disease (PAD). However, their prognostic impact in patients with PAD remains unknown.
OBJECTIVES: The aim of this study was to examine the prognostic impact of elevated Lp(a) levels in patients with PAD undergoing endovascular therapy (EVT).
METHODS: In total, 1,169 patients who underwent successful EVT for symptomatic PAD between September 2016 and August 2021 were included in this study. High Lp(a) levels were defined as >30 mg/dL. The associations of high Lp(a) levels with incident major adverse cardiovascular events (MACE) (all-cause death, myocardial infarction, and stroke) and major adverse limb events (MALE) (repeat revascularization for target limb and major amputation) were analyzed.
RESULTS: During a median follow-up period of 1.7 years (IQR: 0.6-3.0 years), 230 MACE (210 deaths, 15 myocardial infarctions, and 22 strokes) and 263 MALE (219 reinterventions and 36 major amputations) were observed. The cumulative incidence rate of MACE (48.1% vs 27.3%) and MALE (67.9% vs 27.2%) was significantly higher in patients with high Lp(a) levels (P < 0.001 for both). The adjusted HR were 1.93 (95% CI: 1.44-2.59; P < 0.001) for MACE and 4.15 (95% CI: 3.14-5.50; P < 0.001) for MALE. These associations were not influenced by low-density lipoprotein cholesterol levels or statin administration (P for interaction >0.05 for all).
CONCLUSIONS: Elevated Lp(a) levels were independently associated with incident MACE and MALE in patients with PAD treated with revascularization irrespective of low-density lipoprotein cholesterol level and statin administration.
