We aim to evaluate the disturbances in mineral metabolism, abnormalities in bone mineral density (BMD), and extraskeletal calcification in newly detected, untreated predialysis stage 4 and 5 chronic kidney disease (CKD) patients at a tertiary care hospital in North India. This is cross-sectional observational study. A total of 95 (68 males, 27 females) newly detected patients underwent clinical evaluation, biochemical assessment [serum calcium, phosphorus, alkaline phosphatase (ALP), albumin, creatinine, intact parathyroid hormone (iPTH), 25- hydroxyvitamin D (25(OH)D)], BMD measurement (at spine, hip, and forearm) by dual-energy X-ray absorptiometry (DXA), lateral abdominal radiograph [for abdominal aortic calcification (AAC)], skeletal survey (to look for any abnormality including fractures), and echocardiography [for any cardiac valvular calcification (CVC)]...

Acute poststreptococcal glomerulonephritis (PSGN) is the most common type of glomerulonephritis seen in children. It can affect multiple organs with heart being frequently involved. Yet, there are very few studies on cardiac status in children with PSGN and hence this study was conducted. All consecutive children from 1 month to 12 years of age, admitted over a two-year period with a diagnosis of PSGN, were included in the study. An electrocardiogram (ECG) and two-dimensional echocardiogram were performed in all patients on admission and repeated at six and 12 weeks, if abnormal...

BACKGROUND: Diastolic dysfunction develops in response to hypertension and estrogen (E2) loss and is a forerunner to heart failure (HF) in women. The cardiac renin-angiotensin system (RAS) contributes to diastolic dysfunction, but its role with respect to E2 and blood pressure remain unclear. METHODS: We compared the effects of ovariectomy (OVX) or sham surgery on the cardiac RAS, left ventricular (LV) structure/function, and systemic/intracardiac pressures of spontaneously hypertensive rats (SHRs: n = 6 intact and 6 OVX) and age-matched Wistar-Kyoto (WKY: n = 5 intact and 4 OVX) controls...

Coronary artery bypass grafting (CABG) remains a vital treatment for patients with multivessel coronary artery disease (CAD), especially diabetics. The long-term benefit of the internal thoracic artery graft is well established and remains the gold standard for revascularization of severe CAD. It is not always possible to achieve complete revascularization through arterial grafts, necessitating the use of saphenous vein grafts (SVG). Unfortunately, SVGs do not have the same longevity, and their failure is associated with significant adverse cardiac outcomes and mortality...

The association between uric acid (UA) on one side and systemic hypertension (Htn), dyslipidemia, glucose intolerance, overweight, fatty liver, renal disease and cardiovascular disease (CVD) on the other side is well recognized. However, the causal relationship between UA and these different clinical problems is still debatable. The recent years have witnessed hundreds of experimental and clinical trials that favored the opinion that UA is a probable player in the pathogenesis of these disease entities. These studies disclosed the strong association between hyperuricemia and metabolic syndrome (MS), obesity, Htn, type 2 diabetes mellitus (DM), non-alcoholic fatty liver disease, hypertriglyceridemia, acute kidney injury, chronic kidney disease (CKD), coronary heart disease (CHD), heart failure and increased mortality among cardiac and CKD patients...

Fulminant myocarditis is severe and aggressive, but it is self-limited and usually has a favorable prognosis if the patients can survive the acute phase. When drug treatment is not effective, extracorporeal membrane oxygenation technology should be applied to support cardiopulmonary function. Extracorporeal membrane oxygenation can simultaneously support function of the left ventricle, right ventricle, and lungs, and provide stable blood circulation for patients with heart and respiratory failure, which allows sufficient time for the cardiopulmonary system to recover...

BACKGROUND: Prognosis of hypertrophic cardiomyopathy (HCM) is particularly heterogeneous. Patients with nonobstructive HCM (NOCM) are thought to be at relatively low-risk as compared with obstructive HCM (HOCM) with no need of major treatment options. However, available evidence of NOCM comes mainly from tertiary centers where a referral bias is likely to occur. Aim of this study was to perform a systematic review and meta-analysis of the published literature on hypertrophic cardiomyopathy (HCM) in order to outline differences in presenting features and long-term outcome between NOCM and HOCM...

BACKGROUND: Interleukin-32 (IL-32) is a newly discovered proinflammatory cytokine. However, there are limited data regarding IL-32 as a biomarker for heart failure (HF). In this study, we assessed the prognostic value of IL-32 in patients with chronic HF after myocardial infarction (MI). METHODS AND RESULTS: Over a period of 1.8years, we prospectively enrolled 100 patients with chronic HF after MI. IL-32, NT-proBNP, Matrix metallopeptidase 9 (MMP-9), procollagen type I (PI) and type III (PIII) were measured at baseline...

Meis1 is a member of three-amino-acid loop extension (TALE) homeodomain transcription factors. Studies in the last decade have shown that Meis1 has crucial roles in cardiac regeneration, stem cell function, and tumorigenesis. We have recently demonstrated that knocking out of Meis1 in adult cardiomyocytes resulted in the induction of cardiomyocyte proliferation. This suggests that targeting of Meis1 might be utilized in the manipulation of cardiomyocyte cell cycle post cardiac injuries. In addition, hematopoietic stem cell (HSC) specific deletion of Meis1 leads to in vivo expansion of HSCs pool...

Coronary artery fistulae are rare cardiac anomalies with a prevalence of 0.2% of all the patients undergoing coronary angiography. The majority of them are congenital and generally origin from the right coronary artery. Occasionally acquired (mostly iatrogenic) fistulae can develop. Although frequently subclinical, symptoms of angina and congestive heart failure may occur. We present an unusual well-illustrated case of a strongly dilated circumflex coronary artery with formation of two giant aneurysms and fistulous communication towards the right atrium...

OBJECTIVE: Preliminary data suggest that nonalcoholic fatty liver disease is associated with early heart failure (HF). However, whether nonalcoholic steatohepatitis (NASH) is directly associated with echocardiographic changes in cardiac structure or function remains unknown. METHODS: A retrospective cohort was identified of individuals (N = 65) without known heart disease, undergoing elective bariatric surgery with perioperative liver biopsy, and available recent transthoracic echocardiography (TTE)...

Patients with ischaemic heart disease or chronic heart failure show altered levels of obestatin, suggesting a role for this peptide in human heart function. We have previously demonstrated that GH secretagogues and the ghrelin gene-derived peptides, including obestatin, exert cardiovascular effects by modulating cardiac inotropism and vascular tone, and reducing cell death and contractile dysfunction in hearts subjected to ischaemia/reperfusion (I/R), through the Akt/nitric oxide (NO) pathway. However, the mechanisms underlying the cardiac actions of obestatin remain largely unknown...

BACKGROUND: No precise tools exist to predict appropriate shocks in patients with a primary prevention ICD. We sought to identify characteristics predictive of appropriate shocks in patients with a primary prevention implantable cardioverter defibrillator (ICD). METHODS: Using patient-level data from the Multicenter Automatic Defibrillator Implantation Trial II (MADIT II) and the Sudden Cardiac Death in Heart Failure Trial (SCD-HeFT), we identified patients with any appropriate shock...

Endoplasmic reticulum stress is an evolutionarily conserved cell stress response associated with numerous diseases, including cardiac hypertrophy and heart failure. The major endoplasmic reticulum stress signaling pathway causing cardiac hypertrophy involves endoplasmic reticulum stress sensor PERK (protein kinase-like kinase) and eIF2α-ATF4-CHOP signaling. Here, we describe a non-canonical, AGGF1-mediated regulatory system for endoplasmic reticulum stress signaling associated with increased p-eIF2α and ATF4 and decreased sXBP1 and CHOP...

Rationale: Cardiac fibrosis is a common feature in left ventricular remodeling that leads to heart failure, regardless of the etiology. Erythropoietin-producing hepatoma interactor B2 (EphrinB2), a pivotal bidirectional signaling molecule ubiquitously expressed in mammals, is crucial in angiogenesis during development and disease progression. Recently, EphrinB2 was reported to protect kidneys from injury-induced fibrogenesis. However, its role in cardiac fibrosis remains to be clarified. Objective: We sought to determine the role of EphrinB2 in cardiac fibrosis and the underlying mechanisms during the pathological remodeling process...
