Social isolation presents a risk factor and worsens outcome to cerebrovascular diseases; however, the underlying mechanisms remain underspecified. This study examines the effect of social environment on microglial reactivity after global cerebral ischemia, to test the hypothesis that social isolation leads to greater microglial responses. Adult female and male mice were pair-housed or socially isolated for one week prior to cardiac arrest/cardiopulmonary resuscitation (CA/CPR) or the sham procedure, and following either 2 or 24 h of reperfusion, microglia samples were enriched and analyzed for gene expression...

Data on cardiovascular disease, including arrhythmias, in Africa is limited. However, the burden of cardiovascular disease appears to be on the rise. Recent global data suggests an increase in atrial fibrillation rates despite declining rates of rheumatic heart disease. Atrial fibrillation is also associated with increased mortality in Africa. Current management with medical therapy is sub-optimal and ablation procedures, inaccessible. Atrial fibrillation is also an independent risk factor for death in patients with rheumatic heart disease...

Burn injuries generate multisystem physiological derangements. The authors present a case series of three patients developing acute coronary syndrome (ACS) stemming from coronary vasospasm (CVS) over a course of 5 months. This etiology of ACS is significant as it has previously not been described in burn patients and requires a different management algorithm than vaso-occlusive disease. All patients were admitted to a single accredited burn unit. Burn mechanisms were flash burn, chemical fire, and house fire...

Longitudinal, well phenotyped, population-based cohort studies offer unique research opportunities in the context of genome-wide association studies (GWAS), including GWAS for new-onset (incident) cardiovascular disease (CVD) events, the assessment of gene x lifestyle interactions, and evaluating the incremental predictive utility of genetic information in apparently healthy individuals. Furthermore, comprehensively phenotyped community-dwelling samples have contributed to GWAS of numerous traits that reflect normal organ function (e...

BACKGROUND: Cardiogenic shock (CS) in absence of acute myocardial infarction (AMI) has significant morbidity and mortality. This population of patients has been excluded from prior major randomized trials and observational studies. METHODS: We included patients with CS in absence of AMI from the 2013-14 HCUP's National Readmission Database. 30-day readmissions were studied and etiology for readmission was identified by using ICD-9CM codes in primary diagnosis field...

BACKGROUND: MitraClip implantation has evolved as a new tool for treatment of inoperable or high-risk patients with severe functional mitral regurgitation (FMR) due to dilated cardiomyopathy (DCM). Limited data are available regarding MitraClip outcomes comparing patients with ischemic and non-ischemic DCM. METHODS: From 2008 to 2016, 314 patients received MitraClip for FMR at four institutions: Brescia, Zurich and Milan. Patients were stratified according to MR aetiology in non-ischemic FMR (n = 99) and ischemic FMR (n = 215)...

BACKGROUND: Prior research documents gender gaps in cardiovascular risk management, with women receiving poorer quality routine care on average, even in managed care systems. Although population health management tools and quality improvement efforts have led to better overall care quality and narrowing of racial/ethnic gaps for a variety of measures, we sought to quantify persistent gender gaps in cardiovascular risk management and to assess the performance of routinely used commercial population health management tools in helping systems narrow gender gaps...

Translations of new therapeutic options for cardiovascular disease from animal studies into a clinical setting have been hampered, in part by an improper reflection of a relevant patient population in animal models. In this study, we investigated the impact of thymosin β4 (Tβ4), which promotes collateralization and capillarization, during hypercholesterolemia, a known risk factor of coronary artery disease. Initial in vitro results highlighted an improved endothelial cell function upon Tβ4 treatment under control conditions and during hypercholesterolemic stress (scratch area [pixels]: oxidized low-density lipoprotein [oxLDL], 191,924 ± 7,717; and oxLDL + Tβ4, 105,621 ± 11,245)...

PURPOSE: We aimed to investigate the factors that modulate the extent of QTc prolongation and potential arrhythmogenic consequences during mild therapeutic hypothermia (MTH). METHODS: We studied 205 patients after out-of-hospital cardiac arrest (131 underwent MTH). QTc was measured at baseline, 3h, 6h, 12h, 24h (end of hypothermia), 48h and 72h, and ventricular arrhythmias quantified. RESULTS: During MTH, the QTc interval increased progressively peaking at 12h (mean increase 42ms, 95% CI 30-55)...

PURPOSE: Age-related aortic changes are related to adverse cardiac remodeling and reduced cardiac function. Here, we aim to assess the correlations between aortic arch width (AAW) and left ventricular (LV) remodeling and LV function as well as coronary artery calcification (CAC). MATERIALS AND METHODS: This retrospective study included 194 patients (ages, 67±12 y) who underwent both coronary computed tomography angiography and echocardiography. The AAW is defined as the longest width between the ascending and descending aorta on a transaxial noncontrast coronary computed tomography angiography image at the level of the pulmonary artery bifurcation...

Infective endocarditis is a rare disease that can lead to some diagnostic wandering because of its often nonspecific and polymorphic clinical manifestations. This latency is at the origin of severe cardiac and extra-cardiac complications, yet highly fatal. The clinician should always bear in mind the differential diagnosis of a patient with fever of undetermined origin, with risk factors for valve infection such as foreign material, and history recent invasive procedures (including dental procedures) or recent hospitalization...

Death in patients with postinfarction aneurysms of the left ventricle (LV) is mainly caused by life-threatening ventricular arrhythmias - ventricular tachycardias (VTs) and ventricular fibrillations (VFs). Surgical reconstruction of the LV may potentially lead to disruption of the re-entry mechanism, lying at the basis of ventricular tachyarrhythmias. A series of authors demonstrated high efficacy of such procedures as endocardectomy and radiofrequency ablation of the borderline zone of the LV. But high incidence of relapses, difficulty detecting the localization of VT and performing radiofrequency ablation (RFA), as well as high incidence of spontaneous and induced VTs in patients with postinfarction aneurysms of the LV have preserved dissatisfaction with the currently existing techniques...

A high mean platelet volume (MPV) level has been demonstrated to predict poor clinical outcomes in patients with cardiovascular disease. However, the relationship between MPV and mortality in patients with acute cardiorenal syndrome (ACRS) is unknown. Therefore, we investigated the predictive value of MPV for in-hospital mortality of patients with ACRS who received continuous renal replacement therapy (CRRT) in this study.We retrospectively analyzed the demographics, etiology, severity of illness, prognosis, and risk factors of ACRS patients who underwent CRRT in our hospital from January 2009 to December 2014...

Continuous electroencephalography (CEEG) is chiefly performed at The Medical University of South Carolina (MUSC) for identifying seizures, including its refined use within the epilepsy monitoring unit (EMU) as a differentiator between epileptic and psychogenic etiologies. CEEG also provides critical data that carry implications outside the bounds of both epilepsy and psychogenic events, such as the characterization of unorthodox clinical phenomena that are of physiological (though nonepileptic) origins. Although nonepileptic events (NEEs) are primarily linked with psychogenic phenomena (conversion disorder, malingering) that can mimic epileptic activity, they, like seizures, have diverse semiologies and etiologies...

Cardiac hypertrophy is one of the major risk factors for chronic heart failure. The role of endophilinA2 (EndoA2) in clathrin-mediated endocytosis and clathrin-independent endocytosis is well documented. In the present study, we tested the hypothesis that EndoA2 protects against angiotensin II (Ang II)-induced cardiac hypertrophy by mediating intracellular angiotensin II type 1 receptor (AT1-R) trafficking in neonatal rat cardiomyocytes (NRCMs). Cardiac hypertrophy was evaluated by using cell surface area and quantitative RT-PCR (qPCR) analyses...
