Objective This study aimed to investigate whether differential expression of the retinoic acid receptor-related orphan receptor A ( RORA) gene is related to occurrence of acute myocardial infarction (AMI). Methods This was a retrospective study. White blood cells of 93 patients with acute myocardial infarction and 74 patients with stable coronary artery disease were collected. Reverse transcription quantitative polymerase chain reaction and western blotting were used to measure RORA mRNA and protein expression, respectively. Results RORA mRNA expression levels in peripheral blood leukocytes in patients with AMI were 1.57 times higher than those in patients with stable coronary artery disease. Protein RORA levels in peripheral blood of patients with AMI were increased. Binary logistic regression analysis showed that high expression of RORA was an independent risk factor for AMI, and it increased the risk of AMI by 2.990 times. Conclusion RORA expression levels in patients with AMI is significantly higher than that in patients with stable coronary artery disease. High expression of RORA is related to AMI and it may be an independent risk factor for AMI.

Virtual histology-intravascular ultrasound (VH-IVUS) has gained increasing utility in the cardiac catheterization laboratory, not only in determining underlying atherosclerotic lesion composition prior to stent placement, but also in clinical studies assessing the natural history of coronary artery disease (CAD) [1]. Furthermore, VH-IVUS has provided an excellent means of quantifying disease progression by comparing data sets collected over time (i.e., longitudinal studies) and potentially identifying rapidly progressing and potentially vulnerable plaques. One difficulty, however, in analyzing VH-IVUS derived CAD progression is the accurate co-registration of image sets collected over a period of time. Commonly, an expert VH-IVUS image reader reviews these image sets side-by-side on a display and co-registers images along the vessel main axis, herein axially co-registered, by identifying image locations relative to fiduciary anatomical markers (e.g., branches). Despite this method being the standard for analyzing CAD progression, it is limited by the inability to accurately co-register VH-IVUS data in the circumferential direction (i.e., rotating images such that their cylindrical coordinate bases coincide; herein circumferentially co-registered). Thus, a significant amount of information on focal plaque progression is lost that could provide a greater understanding of the natural evolution of CAD, the effects of various pharmaceutical agents (e.g., statins) on lesion composition changes, and the impact of local mechanical factors that induce plaque progression/regression and transformation.

Paraoxonase-1 (PON1), a high-density-lipoprotein- (HDL-) associated enzyme, has the potential to protect against atherogenesis. We examine the relationships between plasma PON1 activity and the progression of atherosclerosis as well as coronary artery disease (CAD). Fasting blood samples were collected from female apolipoprotein E-deficient (apoE−/−) mice and 149 patients undergoing coronary angiography for the biochemical parameters measurement. The severity of CAD was defined using angiographic Gensini score (GSS). Compared to 3-month-old apoE−/−mice, aged mice had significantly lower PON1 activity, which is negatively correlated with the size of atherosclerotic lesion and plasma interleukin-6 (IL-6) and tumor necrosis factorα(TNF-α) levels. In study patients, PON1 activity was correlated with age, sex, and HDL-cholesterol, apolipoprotein AI, and high-sensitivity C-reactive protein (hs-CRP) levels and was significantly lower in CAD group than that in non-CAD control group. Interestingly, PON1 activity in severe CAD group (GSS > 40) was further significantly reduced compared to those in mild and moderate subgroups (GSS  ≤ 40) (P<0.01). There is a significant correlation between PON1 activity and the severity of CAD as assessed by GSS (r=-0.393,P<0.001). PON1 activity may be a potential biomarker for the severity of CAD.

Research has lead to a better understanding of the pathophysiology and history of atherosclerotic heart disease, which has reached epidemic proportions in industrialized countries in this century. Atherosclerosis should be seen as a chronic, protracted process that encompasses complex and dynamic interactions between cellular, biochemical, and biophysical factors in the microcosmos of the arterial vessel wall and blood circulation. In this context, the ultimate consequences of this disease process, namely coronary artery disease, must be seen as the "tip of the iceberg." The most dramatic manifestation of coronary artery disease, the acute coronary syndrome, usually occurs as the result of different forces and factors, which lead to abrupt plaque disruption, rupture, and vessel thrombosis. In contrast, the genesis of this atherosclerotic lesion is a slow process. Despite considerable experimental clinical evidence accrued during the past decade, atherosclerosis remains a complex pathophysiological process that is not fully understood. It is clear, however, that the interaction between the cellular elements of the vessel wall and the circulation are the determinants of atheroma formation. In this regard, the vascular endothelium appears to play a pivotal role because of its strategic location and metabolic activity. Antilipidemic therapy influences the outcome of coronary disease through a variety of mechanisms, including direct and indirect effects on the endothelium.
