Angiogenesis-related proteins as biomarkers for peripheral artery disease.

ABSTRACT:

Background

Angiogenesis plays an important role in peripheral artery disease (PAD) and angiogenesis-related proteins may act as prognostic biomarkers. This study assesses the potential for angiogenesis-related proteins to predict adverse events associated with PAD.

Methods

This was a case-control study. Patients with PAD (n = 250) and without PAD (n = 125) provided blood samples and were followed prospectively for three years. Concentrations of 17 angiogenesis-related proteins were measured in plasma. The incidence of major adverse limb event (MALE), defined as a composite of major amputation or vascular intervention, was the primary outcome. Worsening PAD status, defined as a drop in ankle brachial index ≥ 0.15, was the secondary outcome. Multivariable regression adjusted for baseline characteristics was conducted to determine the prognostication value of angiogenesis-related proteins in predicting MALE.

Findings

Relative to patients without PAD, 8 proteins related to angiogenesis were expressed differentially in PAD patients. Worsening PAD status and MALE were observed in 52 (14%) and 83 (22%) patients, respectively. Hepatocyte growth factor (HGF) was the most reliable predictor of MALE (adjusted HR 0.79, 95% CI 0.15-0.86). Compared to individuals with high HGF, patients with low HGF had a decreased three-year freedom from MALE [66% vs 88%, p = 0.001], major amputation [93% vs 98%, p = 0.023], vascular intervention [68% vs 88%, p = 0.001], and worsening PAD status [81% vs 91%, p = 0.006].

Interpretation

Measuring plasma levels of HGF in individuals with PAD can assist in identifying patients at elevated risk of adverse events related to PAD who may benefit from additional evaluation or treatment.

Project description:BackgroundNT-proBNP (N-terminal pro-B-type natriuretic peptide), high-sensitivity cardiac troponin T (hs-troponin T), and high-sensitivity cardiac troponin I (hs-troponin I) are increasingly being recommended for risk stratification for a variety of cardiovascular outcomes. The aims of our study were to establish the prevalence and associations of elevated NT-proBNP, hs-troponin T, and hs-troponin I with lower extremity disease, including peripheral artery disease (PAD) and peripheral neuropathy (PN), in the US general adult population without known cardiovascular disease. We also assessed whether the combination of PAD or PN and elevated cardiac biomarkers was associated with an increased risk of all-cause and cardiovascular mortality.MethodsWe conducted a cross-sectional analysis of the associations of NT-proBNP, hs-troponin T, and hs-troponin I with PAD (based on ankle-brachial index <0.90) and PN (diagnosed by monofilament testing) in adult participants aged ≥40 years of age without prevalent cardiovascular disease in NHANES (National Health and Nutrition Examination Survey) 1999 to 2004. We calculated the prevalence of elevated cardiac biomarkers among adults with PAD and PN and used multivariable logistic regression to assess the associations of each cardiac biomarker, modeled using clinical cut points, with PAD and PN separately. We used multivariable Cox proportional hazards models to assess the adjusted associations of cross categories of clinical categories of each cardiac biomarker and PAD or PN with all-cause and cardiovascular mortality.ResultsIn US adults aged ≥40 years, the prevalence (±SE) of PAD was 4.1±0.2% and the prevalence of PN was 12.0±0.5%. The prevalence of elevated NT-proBNP (≥125 ng/L), hs-troponin T (≥6 ng/L), and hs-troponin I (≥6 ng/L for men and ≥4 ng/L for women) was 54.0±3.4%, 73.9±3.5%, and 32.3±3.7%, respectively, among adults with PAD and 32.9±1.9%, 72.8±2.0%, and 22.7±1.9%, respectively, among adults with PN. There was a strong, graded association of higher clinical categories of NT-proBNP with PAD after adjusting for cardiovascular risk factors. Clinical categories of elevated hs-troponin T and hs-troponin I were strongly associated with PN in adjusted models. After a maximum follow-up of 21 years, elevated NT-proBNP, hs-troponin T, and hs-troponin I were each associated with all-cause and cardiovascular mortality, with higher risks of death observed among adults with elevated cardiac biomarkers plus PAD or PN compared with elevated biomarkers alone.ConclusionsOur study establishes a high burden of subclinical cardiovascular disease defined by cardiac biomarkers in people with PAD or PN. Cardiac biomarkers provided prognostic information for mortality within and across PAD and PN status, supporting the use of these biomarkers for risk stratification among adults without prevalent cardiovascular disease.
