BACKGROUND: Hypertension is an increased risk of heart failure and acute myocardial infarction (MI). Tert-butylhydroquinone (tBHQ), as an antioxidant, shows multiple cardioprotective actions including the reduction in blood pressure. The aim of this study was to investigate whether and how tBHQ improves heart functions in rats. METHODS: The MI model was established in WKY and spontaneously hypertensive rats (SHRs) by ligation of left anterior descending coronary artery...

BACKGROUND: Most acute coronary syndromes are caused by the fracture of a vulnerable atherosclerotic plaque. These plaques are thin cap fibroatheromas, which can only be detected with invasive coronary imaging techniques. It is necessary to find a non-invasive biomarker of these vulnerable plaques in order to identify patients at risk without a coronary angiography. Metalloproteinase-1 is an enzyme involved in extracellular matrix metabolism which has been correlated with the rupture of atherosclerotic plaques...

Blood flow through healthy human vessels releases NO to produce vasodilation, whereas in patients with coronary artery disease (CAD), the mediator of dilation transitions to mitochondria-derived hydrogen peroxide (mtH2O2). Excessive mtH2O2 production contributes to a proatherosclerotic vascular milieu. Loss of PGC-1α (peroxisome proliferator-activated receptor γ coactivator 1α) is implicated in the pathogenesis of CAD. We hypothesized that PGC-1α suppresses mtH2O2 production to reestablish NO-mediated dilation in isolated vessels from patients with CAD...

BACKGROUND: Contrast induced nephropathy (CIN) may be defined as Acute Renal Failure (ARF) that occurs within 24-72h of exposure to intra-venous or intra-arterial iodinated contrast media that cannot be attributed to other causes. CIN occurs in up to 5% of hospitalized patients with normal renal function prior to injection of contrast media. It occurs more frequently in patients with renal impairment particularly if associated with diabetic nephropathy. Among all procedures utilizing contrast agents for either diagnostic or therapeutic purposes, coronary angiography and percutaneous coronary interventions are associated with the highest rates of CIN...

Aims: Near-infrared spectroscopy (NIRS) is able to quantify cholesterol within coronary arteries by the lipid core burden index (LCBI). We studied the prognostic value of NIRS-derived LCBI in patients with coronary artery disease (CAD) for adverse cardiac outcome during long-term follow-up. Methods and results: During 2009-2013, NIRS was performed in a non-culprit artery of 275 patients undergoing coronary angiography for acute coronary syndrome (ACS) or stable angina...

BACKGROUND Isolated ST elevation in lead aVR in combination with global ST depression with normalization after rehydration is a unique electrocardiographic pattern that is associated with a broad range of diagnoses. Its association with left main coronary artery disease and other acute coronary syndromes suggest the need for early and aggressive cardiac evaluation.

OBJECTIVE: Recent technical developments enable skin fluorescence to be quantified in vivo in humans. The present study aimed at determining whether flow mediated skin fluorescence was reproducible, sensitive to changes within an individual, and if it could differ between patients with coronary artery disease and healthy volunteers. METHODS: First, forearm flow mediated skin fluorescence recorded during and after brachial artery occlusion was assessed following successive forearm occlusion periods (1, 2, 3 and 5min) and expressed as ischemic and hyperemic responses (as % of baseline)...

INTRODUCTION: Posttraumatic stress disorder (PTSD) develops in 1 out of 8 survivors of acute coronary syndrome (ACS) events, and these persons have a doubling of risk for recurrent ACS and mortality. Overcrowding in the emergency department during ACS evaluation has been associated with increased risk for PTSD, and depressed patients have been found to be particularly vulnerable. Little is known about the mechanisms by which overcrowding increases PTSD risk in depressed patients. Our aim was to evaluate one possible mechanism, patient perception of crowding and care, in depressed and nondepressed ED patients evaluated for ACS...

BACKGROUND AND AIMS: Many coronary artery disease (CAD) patients exhibit chronic low-grade inflammation. Carotenoids are anti-oxidants with potential anti-inflammatory properties. Here, we first assessed relationships between interleukin (IL)-6 and individual carotenoids in plasma from CAD patients. Based on the results, we proceeded to assess anti-inflammatory effects of one carotenoid, lutein, in peripheral blood mononuclear cells (PBMCs) from CAD patients. METHODS: Lutein + zeaxanthin (isomers with lutein being dominant), β-cryptoxanthin, lycopene, α- and β-carotene and IL-6 were measured in plasma from 134 patients with stable angina (SA) and 59 patients with acute coronary syndrome...

BACKGROUND: Morbidity and mortality from cardiovascular diseases have decreased since the 1970s in most Western societies. However, it is unclear if this positive trend can also be found in younger women suffering from acute coronary syndrome (ACS). METHODS: This is a prospective single center registry study including 11.015 women and men hospitalized for a first ACS between the years 2001 and 2010. We analyzed ACS rates according to sex and age group using Poisson regression in order to assess temporal trends...

Amy Sarma, Nandita S Scott
Despite continued advances in the field, cardiovascular disease remains the leading cause of death in women in the USA with an annual mortality rate that has remained higher for women as compared to men. The factors leading to this sex difference remain incompletely understood. Likely contributors include atypical symptoms at presentation and lack of recognition of cardiovascular risk by women and their providers alike. In addition, women have a higher burden of comorbidities at the time of disease diagnosis and can have differential pathophysiological mechanisms of their acute events...

Background. Neutrophils are involved in the pathogenesis of atherosclerosis by neutrophil extracellular trap (NET) formation. We hypothesized that the NET formation of neutrophils might be changed in end-stage renal disease (ESRD) patients, explaining their higher incidence of coronary artery diseases (CAD). Method. A cross-sectional study was performed in 60 maintenance hemodialysis (MHD) patients, 30 age- and sex-matched healthy individuals (HV, negative control), and 30 patients with acute infection (positive control)...

Percutaneous transluminal coronary angioplasty with coronary stent implantation is a life-saving medical procedure that has become, nowadays, the most frequent performed therapeutic procedure in medicine. Plain balloon angioplasty, bare metal stents, first and second generation drug-eluting stents, bioresorbable and bioabsorbable scaffolds have offered diachronically a great advance against coronary artery disease and have enriched our medical armamentarium. Stented areas constitute vulnerable sites for endothelial damage, endothelial dysfunction, flow turbulence, hemorheologic changes, platelet dysfunction, coagulation changes and fibrinolytic disturbances...

BACKGROUND: Deficiency of the von Willebrand factor-cleaving protease ADAMTS13 is central to the pathophysiology of thrombotic thrombocytopenic purpura (TTP), a microangiopathic syndrome that presents as an acute medical emergency. In this review we will explore the evidence of a two-way relationship between TTP and ACS. Moreover, we will review the evidence emerged from epidemiological studies of an inverse relationship between the plasma levels of ADAMTS13 and the risk of ACS. METHODS AND RESULTS: Pubmed, MEDLINE and EMBASE, CINHAL, COCHRANE and Google Scholar databases were searched from inception to January 2017...

OBJECTIVES: Anomalous aortic origin of a coronary artery is uncommon but potentially clinically significant. Manifestations vary from asymptomatic patients to those who present with angina pectoris, myocardial infarction, heart failure, syncope, arrhythmias, and sudden death. We describe our experience with surgical reimplantation and results at midterm follow-up. METHODS: Between February 2003 and July 2016, a total of 13 patients with anomalous origin of the right coronary artery (RCA) from the left sinus underwent surgical reimplantation...
