BACKGROUND: The AIM-HIGH (Atherothrombosis Intervention in Metabolic Syndrome with Low HDL/High Triglycerides and Impact on Global Health Outcomes) trial failed to demonstrate incremental clinical benefit of extended-release niacin (ERN) in 3414 statin-treated patients with established cardiovascular (CV) disease who had low baseline levels of high-density lipoprotein cholesterol (HDL-C) as compared to placebo. A previous secondary analysis suggested that ERN provided outcome benefits in ERN-treated patients with high triglycerides (TGs; >200 mg/dL) and very low HDL-C (<32 mg/dL) at baseline...

Sharonne N Hayes, Esther S H Kim, Jacqueline Saw, David Adlam, Cynthia Arslanian-Engoren, Katherine E Economy, Santhi K Ganesh, Rajiv Gulati, Mark E Lindsay, Jennifer H Mieres, Sahar Naderi, Svati Shah, David E Thaler, Marysia S Tweet, Malissa J Wood
Spontaneous coronary artery dissection (SCAD) has emerged as an important cause of acute coronary syndrome, myocardial infarction, and sudden death, particularly among young women and individuals with few conventional atherosclerotic risk factors. Patient-initiated research has spurred increased awareness of SCAD, and improved diagnostic capabilities and findings from large case series have led to changes in approaches to initial and long-term management and increasing evidence that SCAD not only is more common than previously believed but also must be evaluated and treated differently from atherosclerotic myocardial infarction...

RATIONALE: Endocardium is the major source of coronary endothelial cells (ECs) in the fetal and neonatal hearts. It remains unclear whether endocardium in the adult stage is also the main origin of neovascularization after cardiac injury. OBJECTIVE: To define the vascular potential of adult endocardium in homeostasis and after cardiac injuries by fate-mapping studies. METHODS AND RESULTS: We generate an inducible adult endocardial Cre line ( Npr3 [natriuretic peptide receptor C]- CreER ) and show that Npr3-CreER efficiently and specifically labels endocardial cells but not coronary blood vessels in the adult heart...

BACKGROUND: The causal role of high-density lipoprotein (HDL) cholesterol in cardioprotection has been questioned by genetic and randomized studies. Novel measures that relate to HDL function may contribute new information to the prediction of cardiovascular risk. Apolipoprotein C-III (apoC-III) is a key regulator of lipoprotein metabolism. We investigated whether subspecies of HDL defined by apoC-III are associated with coronary heart disease (CHD). METHODS: We used immunoaffinity chromatography to measure the apoA-I concentrations of HDL that contains and lacks apoC-III in 2 prospective studies of adults free of CHD...

Aims: Coronary microvascular ischaemia, cardiomyocyte injury and stiffness may play an important role in the pathophysiology of heart failure with preserved ejection fraction (HFpEF). To date, the relationship between coronary flow reserve (CFR), myocardial injury, diastolic dysfunction, and future HFpEF risk is unknown. Methods and results: Consecutive patients (n = 201) undergoing evaluation for suspected coronary artery disease (CAD) with stress myocardial perfusion positron emission tomography, serum troponin, and transthoracic echocardiography who did not have flow-limiting CAD or reduced left ventricular ejection fraction were identified...

BACKGROUND: Evaluation of cardiovascular prognosis in patients with stable coronary heart disease is based on clinical characteristics and biomarkers indicating dysglycemia, dyslipidemia, renal dysfunction, and possibly cardiac dysfunction. Inflammation plays a key role in atherosclerosis, but the association between inflammatory biomarkers and clinical outcomes is less studied in this population. METHODS AND RESULTS: Overall, 15 828 patients with coronary heart disease in the STABILITY (Stabilization of Atherosclerotic Plaque by Initiation of Darapladib Therapy) trial were randomized to treatment with darapladib or placebo and observed for a median of 3...

The authors determined the effect of high-intensity aerobic interval training on arterial stiffness and microvascular dysfunction in patients with metabolic syndrome with hypertension. Applanation tonometry was used to measure arterial stiffness and laser Doppler flowmetry to assess microvascular dysfunction before and after 6 months of stationary cycling (training group; n = 23) in comparison to a group that remained sedentary (control group; n = 23). While no variable improved in controls, hypertension fell from 79% (59%-91%) to 41% (24%-61%) in the training group, resulting in lower systolic and diastolic pressures than controls (-12 ± 3 and -6 ± 2 mm Hg, P < ...

Standardization of diagnostic criteria for ischemic symptoms due to coronary microvascular dysfunction (CMD) is needed for further investigation of patients presenting with anginal chest pain consistent with "microvascular angina" (MVA). At the annual Coronary Vasomotion Disorders International Study Group (COVADIS) Summits held in August 2014 and 2015, the following criteria were agreed upon for the investigative diagnosis of microvascular angina: (1) presence of symptoms suggestive of myocardial ischemia; (2) objective documentation of myocardial ischemia, as assessed by currently available techniques; (3) absence of obstructive CAD (<50% coronary diameter reduction and/or fractional flow reserve (FFR) >0...

INTRODUCTION: Acute coronary syndrome is one of the most adverse prognostic clinical forms of ischemic heart disease. In recent years, attention of researchers and cardiologists practical attract female patients due to a substantial increase in the prevalence including acute coronary syndrome, differences in the causes and features of its course. Women often diagnosed myocardial infarction without ST elevation and nonobstructive coronary heart disease associated with coronary spasm or stratification of coronary artery...

BACKGROUND: Categorization as a cytochrome P450 (CYP) 2C19 poor metabolizer (PM) is reported to be an independent risk factor for cardiovascular disease. Epoxyeicosatrienoic acids (EETs) are metabolites of arachidonic acid by CYP2C19 epoxygenases and anti-inflammatory properties, especially in microvascular tissues. We examined the impact of CYP2C19 polymorphisms and EETs on the patients with microvascular angina (MVA) caused by coronary microvascular dysfunction. METHODS AND RESULTS: We examined CYP2C19 genotypes in patients with MVA (n = 81)...

BACKGROUND: Coronary endothelial dysfunction (CED) is an early stage of atherosclerosis and is associated with adverse cardiovascular events. Inflammation may play a role in the development of endothelial dysfunction. To date no study has evaluated the relationship between C-reactive protein and CED. We aimed to determine if C-reactive protein is associated with CED. METHODS: In 1016 patients (mean age 50.7±12.3 years, 34% male) presenting to the catheterization laboratory with chest pain and non-obstructive coronary artery disease, coronary vasoreactivity was assessed by measuring the percent change in coronary blood flow (%ΔCBF) and coronary artery diameter (%ΔCAD) in response to intracoronary acetylcholine...

There are scarce data regarding risk factors and prognosis of patients with premature ST segment elevation myocardial infarction (STEMI) and "normal or near normal" coronary arteries (N/NNCAs). We compared the characteristics and long-term prognosis of patients with premature STEMI and N/NNCAs with their counterparts with significant coronary artery disease (CAD). We recruited 330 patients who had STEMI ≤35 years of age and 167 age- and gender-matched controls. All patients underwent coronary angiography...

BACKGROUND: Loss-of-function variants in the angiopoietin-like 3 gene (ANGPTL3) have been associated with decreased plasma levels of triglycerides, low-density lipoprotein (LDL) cholesterol, and high-density lipoprotein (HDL) cholesterol. It is not known whether such variants or therapeutic antagonism of ANGPTL3 are associated with a reduced risk of atherosclerotic cardiovascular disease. METHODS: We sequenced the exons of ANGPTL3 in 58,335 participants in the DiscovEHR human genetics study...

It is increasingly recognized that obesity is a risk factor for microvascular disease, involving both structural and functional changes in the microvasculature. This review aims to describe how obesity impacts the microvasculature of a variety of tissues, including visceral adipose tissue, skeletal muscle, heart, brain, kidneys, and lungs. These changes involve endothelial dysfunction, which in turn (i) impacts control of vascular tone, (ii) contributes to development of microvascular insulin resistance, (iii) alters secretion of paracrine factors like nitric oxide and endothelin, but (iv) also influences vascular structure and perivascular inflammation...

REVIEW
Julia C Kuszewski, Rachel H X Wong, Peter R C Howe
Long-chain omega-3 polyunsaturated fatty acids (LCn-3 PUFA) may improve brain functions by acting on endothelial cells in the cerebrovasculature to facilitate vasodilatation and perfusion. The aim of this review is to explore this hypothesis by analyzing the effect of LCn-3 PUFA supplementation on systemic vasodilator and cognitive function and finding evidence to link LCn-3 PUFA intake, vasodilator function and cognition. Forty randomized controlled trials examining the effect of LCn-3 PUFA supplementation in humans on either endothelial vasodilator function or cognition were identified and pooled effects measured with a weighted analysis...

BACKGROUND: Patients with microvascular angina (exertional angina, positive exercise tests and normal coronary arteriograms) usually have a reduced coronary blood flow reserve. Neuropeptide Y (NPY) is a potent endogenous vasoconstrictor involved in modulation of coronary vasomotor tone and may play a role in microvascular angina. METHODS: We compared the effects of NPY (0.2-1.0pmol/kg, intracoronary) on the vasomotor response of proximal and distal segments of the coronary arteries in 7 patients with microvascular angina, 9 with chronic stable angina, and 9 control individuals...
