Atherosclerosis starts as an asymptomatic but progressive condition. A combination of genetics, lifestyle and other underlying (metabolic) disorders make it a life-threatening condition causing coronary heart disease (CHD) and potentially death. Polymorphonuclear neutrophils play a pivotal role in inflammation and atherogenesis as they release human neutrophil peptides (HNP) in case of an acute coronary vascular disorder. This cross-sectional study assesses the correlation between α-defensin expression and the development of CHD. It also evaluates the predictive use of this marker for evaluating CHD risk.

HNP1-3 levels were determined in hyperlipemic patients, CHD patients and health controls using an ELISA kit (Cat. # HK317). Results demonstrated that there was a trend of increased plasma HNP1-3 in hyperlipidemia and CHD patients. Furthermore, CHD patients had higher HNP1-3 levels than hyperlipidemia patients. Based on these results, α-defensin expression has potential as an inflammatory marker for predicting CHD in hyperlipidemia patients.
