Abstract

Background: Heat shock proteins (HSPs) act as chaperones and have a protective function in cardiovascular diseases. The clinical association of a novel small HSPB7 with cardiovascular disease, however, has not been reported. The aim of this study was to investigate the potential biological functions of HSPB7 and its relationship with acute coronary syndrome (ACS). Methods and Results: A mouse myocardial infarction (MI) model and samples from clinical human subjects were used to determine plasma HSPB7 concentration after acute MI. The associations of plasma HSPB7 concentration with ACS and other risk factors of coronary artery disease were analyzed. Plasma HSPB7 concentration was found to be rapidly elevated in mice after coronary artery ligation. In addition, plasma HSPB7 concentration was significantly higher in patients with ACS than in control patients with non-cardiac chest pain (5.1 ng/ml vs. 2.9 ng/ml, P
