Background -Data from before the 2000s indicate the majority of incident cardiovascular disease (CVD) events occur among US adults with systolic and diastolic blood pressure (SBP/DBP)≥140/90 mmHg. Over the past several decades, BP declined and hypertension control has improved. Methods -We estimated the percentage of incident CVD events that occur at SBP/DBP<140/90 mmHg in a pooled analysis of three contemporary US cohorts: the Reasons for Geographic and Racial Differences in Stroke (REGARDS) study, the Multi-Ethnic Study of Atherosclerosis (MESA), and the Jackson Heart Study (JHS) (n=31,856; REGARDS=21,208; MESA=6,779; JHS=3,869)...

BACKGROUND: Coronary artery calcification (CAC) is a predictor of cardiovascular events and plaque burden and is closely associated with chronic inflammation. Interleukin (IL)-37 is a newly discovered member of the IL-1 family and is considered an anti-inflammatory cytokine. Our recent study on mice indicated that IL-37 could attenuate atherosclerosis and vascular calcification, which suggests that IL-37 could be associated with the development of atherosclerosis and related diseases...

Conventional risk factors have limited ability to predict recurrent events in subjects with first-time coronary artery disease (CAD). This aim of this study was to identify novel biomarkers using comparative global proteome analysis to improve the risk assessment for recurrent coronary events. We used samples from phase-I of the Indian Atherosclerosis Research Study (IARS), consisting of 2,332 subjects, of whom 772 were CAD-affected subjects, including 152 with recurrent events identified during a 5-year follow-up period...

OBJECTIVES: This study sought to determine whether coronary artery calcium (CAC) could be used to optimize statin allocation among individuals for whom trial-based evidence supports efficacy of statin therapy. BACKGROUND: Recently, allocation of statins was proposed for primary prevention of atherosclerotic cardiovascular disease (ASCVD) based on proven efficacy from randomized controlled trials (RCTs) of statin therapy, a so-called trial-based approach. METHODS: The study used data from MESA (Multi-Ethnic Study of Atherosclerosis) with 5,600 men and women, 45 to 84 years of age, and free of clinical ASCVD, lipid-lowering therapy, or missing information for risk factors at baseline examination...

Several large-scale genome-wide association studies have identified single-nucleotide polymorphisms in the genomic region of A Disintegrin And Metalloproteinase with ThromboSpondin type 1 repeats (ADAMTS)-7 and associations to coronary artery disease. Experimental studies have provided evidence for a functional role of ADAMTS-7 in both injury-induced vascular neointima formation and development of atherosclerotic lesions. However, whether ADAMTS-7 is associated with a specific plaque phenotype in humans has not been investigated...

In patients with stable coronary artery disease, clinical outcomes are predominantly characterized by the consequences of atherosclerosis on the myocardium, but also by complications of atherosclerosis, notably recurrent acute coronary syndrome or stroke. Secondary prevention therapy is therefore key in this patient population. Intensification of secondary prevention therapy is possible, at the price of a therapeutic risk or a high cost, therefore justifying careful selection of patients with a high residual risk and low therapeutic risk...

BACKGROUND/AIM: Acetylsalicylic acid (ASA) treatment in diabetic patients is very important owing to the increasing hyperactivity of thrombocytes and atherosclerosis. In several investigations, it was reported that diabetes caused increased coronary artery disease, cerebrovascular disease, and death. In this study, we aimed to investigate the effect of ASA on osmoregulation, glycemic control, and some biochemical parameters in rats induced with experimental diabetes type 2. MATERIALS AND METHODS: Twenty-four rats were randomly divided in four groups: control (I), ASA control (II), diabetic (III), and ASA diabetic (IV)...

Cardiovascular diseases are the leading cause of death of death in Taiwan. Atherosclerosis can lead to serious problems, including heart attack, stroke, or even death. Coronary heart disease (CHD) occurs when plaque builds up in the coronary arteries to cause the ischemic heart disease which will enhance myocardial remodeling and also induce myocardial hypoxia. High density lipoprotein (HDL) has been proposed to have cardio-protective effects. Under hypoxic conditions (1%O2 for 24hr), in H9c2 cells, reactive oxygen species (ROS) is induced which leads to cardiomyocyte apoptosis and cardiac dysfunction...

BACKGROUND: Differences in the distribution of the MTRR rs326119 polymorphism (c.56 + 781 A > C) between patients with congenital heart disease (CHD) and controls have been described in Chinese individuals. The association is thought to be due to deregulation of homocysteine-cobalamin pathways. This has not been replicated in other populations. The primary objective of this study was to assess the influence of the MTRR rs326119 polymorphism on biochemical parameters of vitamin B12 metabolism, coronary lesions, and congenital heart disease in Brazilian subjects...

REVIEW
Théophile Godfraind
In the mid 1960s, experimental work on molecules under screening as coronary dilators allowed the discovery of the mechanism of calcium entry blockade by drugs later named calcium channel blockers. This paper summarizes scientific research on these small molecules interacting directly with L-type voltage-operated calcium channels. It also reports on experimental approaches translated into understanding of their therapeutic actions. The importance of calcium in muscle contraction was discovered by Sidney Ringer who reported this fact in 1883...

Blood flow influences atherosclerosis by generating wall shear stress, which alters endothelial cell (EC) physiology. Low shear stress induces dedifferentiation of EC through a process termed endothelial-to-mesenchymal transition (EndMT). The mechanisms underlying shear stress-regulation of EndMT are uncertain. Here we investigated the role of the transcription factor Snail in low shear stress-induced EndMT. Studies of cultured EC exposed to flow revealed that low shear stress induced Snail expression. Using gene silencing it was demonstrated that Snail positively regulated the expression of EndMT markers (Slug, N-cadherin, α-SMA) in EC exposed to low shear stress...

Coronary artery aneurysm (CAA) is a rare anomaly. The right coronary artery is the most commonly affected, followed by the left circumflex (LCX), or the left anterior descending artery (LAD). Three-vessel disease or left main (LM) involvement is extremely rare. A giant coronary artery aneurysm (GCAA) has an extremely low incidence and refers to an aneurysm that is 20 mm or greater in size. Most CAAs occur as a consequence of atherosclerosis. Most patients with CAA are males, have three-vessel disease, and a history of myocardial infarction (MI)...

Frailty is a risk factor for cardiovascular diseases (CVD), but the studies available have not considered the presence of sub-clinical atherosclerotic disease as potential confounders. We investigated the association between frailty and the onset of CVD independently of sub-clinical atherosclerotic disease. For this reason, a sample of 3818 older participants participating in the Age, Gene/Environment SusceptibilityReykjavik Study (AGESReykjavik) without CVD at baseline was followed for a median of 8...
