Objective:
Inflammation is associated with atherogenesis. Although a higher neutrophil count is associated with the plaque burden, the role of neutrophil activation is unclear. Human neutrophil peptides 1-3 (HNP1-3) are a risk factor for atherogenesis in bench models and are elevated in human atheromas. This study aimed to examine the association between skin HNP1-3 deposition and the severity of coronary artery disease (CAD), including long-term outcomes.
Methods:
HNP1-3 levels were immunohistochemically quantified in skin biopsies, which were prospectively taken from 599 consecutive patients before clinically indicated coronary angiography. Established cardiovascular risk factors and blood markers for atheroinflammation were obtained. CAD severity and the incidence of repeat revascularization and mortality at 48 months of follow-up were assessed in relation to HNP1-3 levels.
Results:
The risk of CAD was independently associated with age and HNP1-3 in the entire cohort (F = 0.71 and F = 7.4, respectively). Additionally, HNP1-3 levels were significantly associated with myocardial necrosis (R = 0.26). At the follow-up, high HNP1-3 levels negatively affected mortality (19.54%) and recurrent revascularization (8.05%).
Conclusion:
HNP1-3 tissue deposition is positively associated with the severity of CAD, myonecrosis, and long-term sequelae. HNP1-3 levels may be suppressed using colchicine.
