BACKGROUND: Prior trials comparing a strategy of optimal medical therapy with or without revascularization have not shown that revascularization reduces cardiovascular events in patients with stable ischemic heart disease (SIHD). However, those trials only included participants in whom coronary anatomy was known prior to randomization and did not include sufficient numbers of participants with significant ischemia. It remains unknown whether a routine invasive approach offers incremental value over a conservative approach with catheterization reserved for failure of medical therapy in patients with moderate or severe ischemia...

BACKGROUND: The patho-etiology of mitral regurgitation (MR) has been suggested as a mediator of outcomes following mitral valve (MV) operations, particularly in ischemic functional mitral regurgitation (IMR). This study examined the independent association of MV etiology with mortality. METHODS: Using the Society of Thoracic Surgeons Database, all patients undergoing mitral valve replacement or repair from 2011-2014 were assessed. Patients who underwent concomitant surgical ablation, septal defect closure, tricuspid valve repair, or coronary artery bypass grafting were included...

Cardiovascular diseases are risk factors for dementia, but the mechanisms remain elusive. Here, we report that myocardial infarction (MI) generated by the ligation of the left coronary artery (LCA) could lead to increased miR-1 levels in the hippocampus and blood with neuronal microtubule damage and decreased TPPP/p25 protein expression in the hippocampus. These changes could be prevented by a knockdown of miR-1 using hippocampal stereotaxic injections of anti-miR-1 oligonucleotide fragments carried by a lentivirus vector (lenti-pre-AMO-miR-1)...

BACKGROUND: The concomitant presence of mitral stenosis (MS) in the setting of symptomatic aortic stenosis represent a clinical challenge. Little is known regarding the outcome of mitral stenosis (MS) patients undergoing transcatheter aortic valve replacement (TAVR) or surgical aortic valve replacement (SAVR). Therefore, we sought to study the outcome of MS patients undergoing aortic valve replacement (AVR). METHOD: Using weighted data from the National Inpatient Sample (NIS) database between 2011 and 2014, we identified patients who were diagnosed with MS...

Ischemic heart disease (IHD) is a leading cause of morbidity and mortality worldwide. Growth hormone secretagogues (GHS) have been shown to improve cardiac function in models of IHD. This study determined whether hexarelin (HEX), a synthetic GHS, preserves cardiac function and morphology in a mouse model of myocardial infarction (MI). MI was induced by ligation of the left descending coronary artery in C57BL/6J mice followed by vehicle (VEH; n = 10) or HEX (0.3 mg/kg/day; n = 11) administration for 21 days...

BACKGROUND: The pharmacological inhibition of Proprotein Convertase Subtilisin/Kexin type 9 (PCSK9) has shown to dramatically impact on low-density lipoprotein-cholesterol (LDL-C) levels and associated cardiovascular (CV) diseases. However, the potential use of PCSK9 serum levels as a CV risk biomarker remains to be clarified. METHODS: 189 patients with severe carotid artery atherosclerosis undergoing carotid endarterectomy (CEA) and whose clinical records and serum sample aliquots for PCSK9 level measurement were available both directly before CEA and at 24-month follow-up were included in the present pilot study...

PURPOSE: Cardiac PET-MR has shown potential for the comprehensive assessment of coronary heart disease. However, image degradation due to physiological motion remains a challenge that could hinder the adoption of this technology in clinical practice. The purpose of this study was to validate a recently proposed respiratory motion-corrected PET-MR framework for the simultaneous visualisation of myocardial viability (18 F-FDG PET) and coronary artery anatomy (coronary MR angiography, CMRA) in patients with chronic total occlusion (CTO)...

Cardiovascular disease is an important complication for patients with chronic kidney disease (CKD), warranting accurate risk prediction, but clinical guidelines are inconsistent regarding whether or how to use information on measures of CKD for predicting risk. Recent large meta-analyses have shown that key CKD measures (estimated glomerular filtration rate and albuminuria) improve cardiovascular risk prediction beyond traditional risk factors, especially when albuminuria is added to prediction models. In addition, several recent studies have shown that the use of filtration markers other than serum creatinine, cystatin C, and β2 -microglobulin can improve cardiovascular risk prediction...

BACKGROUND: Epidemiologic studies suggest reduced cardiovascular disease (CVD) events with moderate alcohol consumption. However, heavy and binge drinking may be associated with higher CVD risk. Utilizing the Nationwide Inpatient Sample, we studied the association between a troublesome alcohol history (TAH), defined as those with diagnoses of both chronic alcohol syndrome and acute withdrawal history and CVD events. METHODS: Patients >18 years with diagnoses of both chronic alcohol syndrome and acute withdrawal using the International Classification of Diseases-Ninth Edition-Clinical Modification (ICD-9-CM) codes 303...

In the Middle East, there is no precise data and literature on tobacco-based products, such as dokha and shisha. The proposed study aims to quantify the levels of nicotine and tar in different kinds of dokha and shisha products that are sold in the local marketplace. The amount of nicotine in dokha and shisha products can be quantitatively determined using a combination of the "kissling" and "silicotungstic acid" method proposed by Robert M. Chapin. The tar residue from the smoke sample was collected on a glass wool placed before the stopcock (tap) of a separatory funnel as the smoke passes through the inlet of an electronically controlled vacuum pump...

Endothelin-1 (ET-1) is associated with endothelial dysfunction and vasoconstriction. Increased circulating ET-1 levels are associated with long-term cardiovascular mortality. Renalase, released from kidney, metabolizes catecholamines and regulates blood pressure. An increase in circulating renalase levels has been reported in patients with chronic kidney disease (CKD) and is associated with coronary artery disease (CAD). We hypothesized the existence of a synergistic effect of serum renalase levels and CKD on ET-1 levels in patients with CAD...

The Industrial Revolution and the accompanying nutritional, epidemiological and demographic transitions have profoundly changed human ecology and biology, leading to major shifts in life history traits, which include age and size at maturity, age-specific fertility and lifespan. Mismatch between past adaptations and the current environment means that gene variants linked to higher fitness in the past may now, through antagonistic pleiotropic effects, predispose post-transition populations to non-communicable diseases, such as Alzheimer disease, cancer and coronary artery disease...

Serum indoxyl sulfate (IS; a uremic toxin) levels, which are significantly higher in patients with chronic kidney disease, including those undergoing hemodialysis, than in the robust, are associated with both cardiovascular disease (CVD) and CVD-related mortality. Furthermore, coronary artery calcium (CAC) is an independent predictor of cardiovascular events in patients undergoing hemodialysis. This study aimed to interpret the association between serum IS levels and coronary plaque burden (CPB) or CAC.A total of 30 consecutive patients on hemodialysis, who underwent 320-row coronary multidetector computed tomography (MDCT) angiography for suspected coronary artery disease, were enrolled in this prospective study...

In a previous report of two married cohabiting couples affected by polymyalgia rheumatica (PMR), we noticed that the wife of one couple and both members of the other couple suffered from symptomatic diverticular disease (DD), whose diagnosis was made before the onset of PMR. We investigated whether DD might be a risk factor for the development of PMR. We conducted a case-control study informed on a database containing the prospectively collected medical records of consecutive PMR patients. Among comorbidities, attention was focused on symptomatic DD, provided that the diagnosis had been made by colonoscopy and/or computed tomography scan...

Patients with post-traumatic stress disorder (PTSD) are at risk of multiple co-morbidities and are more likely to develop incident heart failure with reduced ejection fraction (HFrEF). The relation of PTSD with clinical outcomes in HFrEF is not established. US veterans diagnosed with HFrEF from January 2007 to January 2015 and treated nationwide in the Veterans Affairs (VA) Health System were included in the study. Patients with HFrEF were identified through International Classification of Diseases, Ninth Revision (ICD-9) codes...

We recently found that renal carbonic anhydrase (CA) is involved in the reabsorption of inorganic nitrite (NO2 - ), an abundant reservoir of nitric oxide (NO) in tissues and cells. Impaired NO synthesis in the endothelium and decreased NO bioavailability in the circulation are considered major contributors to the development and progression of renal and cardiovascular diseases in different conditions including diabetes. Isolated human and bovine erythrocytic CAII and CAIV can convert nitrite to nitrous acid (HONO) and its anhydride N2 O3 which, in the presence of thiols (RSH), are further converted to S-nitrosothiols (RSNO) and NO...
