Abstract

Objective: The correlation between lipoproteins and arterial thrombosis is not fully elucidated, and no data exist in terms of lipoprotein profiles before heparin administration in patients with coronary arterial thrombosis (CAT). This cross-sectional study aimed to evaluate the lipoprotein profile before heparin administration in 63 ST-segment elevation myocardial infarction (STEMI) patients with CAT. Methods: The lipoprotein profile was measured via polyacrylamide gel electrophoresis prior to heparin administration for primary percutaneous coronary intervention for STEMI. Age- and sex-matched subjects with

Abstract

The mechanism of stent thrombus formation following percutaneous transluminal stent implantation in an artery is unclear. This case report describes a 72-year-old man who had a mobile thrombus in a Wallstent in the right iliac artery despite daily oral administration of 100 mg of aspirin. This Wallstent was implanted 14 years ago. The unique in vivo angioscopic images show a solid mobile thrombus with some projections which rubbed yellow plaque on the stent struts.

Abstract

Objective: Platelet-derived growth factor (PDGF) induces matrix metalloproteinase (MMP), which is regarded as a biomarker of plaque rupture or vulnerability. The aim of this study is to investigate those interactions in human coronary arteries at the onset of ST-segment elevation myocardial infarction (STEMI). Methods: Thirty-two patients with STEMI who underwent primary percutaneous coronary intervention (PCI) were enrolled in this study. Plasma levels of PDGF-BB and MMP-9 were measured from infarct-related artery (IRA) and from femoral artery (FA) during PCI. Results: Plasma levels of PDGF-BB and MMP-9 in the IRA were significantly higher than those in the FA (PDGF-BB: median 3130 pg/ml, IQR (interquartile range): 2020 to 4375 pg/ml vs. median 2605 pg/ml, IQR: 1305 to 3290 pg/ml, p
