That hypertensive disorders of pregnancy (HDP) affect maternal health even after delivery of the baby and the placenta, is no longer in doubt. Women with a history of HDP, preeclampsia in particular, have well-documented increased risks of later hypertension, ischemic heart disease, myocardial infarction, ischemic stroke, venous thromboembolism, and cardiomyopathy. However, our understanding of how "later" is defined - i.e. when exactly HDP-associated disease risks increase - is shifting. This article is protected by copyright...

BACKGROUND: T wave amplitudes during ventricular repolarization in the lead aVR (TAaVR) are shown to be associated with adverse cardiac events in patients with several cardiovascular diseases, such as postmyocardial infarction. However, the utility of TAaVR has not been previously evaluated in patients with cardiomyopathy who have received implantable cardioverter defibrillators (ICD). Patients with ischemic or nonischemic cardiomyopathy (ICM or NICM, respectively) and who received an ICD may experience worsening of their condition due to the introduction of electric shock during treatment...

Acute myocarditis is a non-ischemic inflammatory disease of the myocardium, and there is currently no standard treatment. Mesenchymal stem cells (MSCs) can alleviate myosin‑induced myocarditis; however, the mechanism has not been clearly elucidated. In the present study, the authors investigated the ability of human umbilical cordMSCs (HuMSCs) to attenuate myocardial injury and dysfunction during the acute phase of experimental myocarditis. Male Lewis rats (aged 8 weeks) were injected with porcine myosin to induce myocarditis...

Hypoxia-induced cardiomyocyte apoptosis plays an important role in the development of ischemic heart disease. MicroRNAs (miRNAs or miRs) are emerging as critical regulators of hypoxia-induced cardiomyocyte apoptosis. miR-200c is an miRNA that has been reported to be related to apoptosis in various pathological processes; however, its role in hypoxia‑induced cardiomyocyte apoptosis remains unclear. In the present study, we aimed to investigate the potential role and underlying mechanism of miR-200c in regulating hypoxia‑induced cardiomyocyte apoptosis...

Intracerebral hemorrhage (ICH), a subtype of stroke, brings high morbidity and mortality to human beings. Multiple studies indicate that neuroinflammation, excitotoxicity, oxidative stress, cytotoxicity resulted from the degradation products of blood clot play vital roles in ICH-induced secondary brain injury, which contributes to deterioration of neurological outcome. Prostaglandin E2 (PGE2), a type of prostanoids commonly up-regulated in these progresses, is known to modulate numerous cellular and molecular processes and involve in various diseases, including ICH, cerebral ischemic, Alzheimer's disease (AD) and amyotrophic lateral sclerosis (ALS) etc...

Background Data from European countries consistently show that guideline-conform secondary prevention after stroke/transient ischemic attack is being realized in only 50-80% of patients. Use of telemedicine to support long-term secondary prevention has been effective in other cardiovascular diseases. Aims We reviewed current evidence for telemedical-supported strategies for the improvement of secondary prevention after stroke/transient ischemic attack. A systematic review was performed in accordance with the PRISMA statement searching MEDLINE, the Cochrane Central Register of Controlled Trials, and reference lists of articles published until 18 May 2016...

Ischemic heart disease is the main cause of death worldwide and is accelerated by increased levels of low-density lipoprotein cholesterol (LDL-C). Proprotein convertase subtilisin/kexin type 9 (PCSK9) is a potent circulating regulator of LDL-C through its ability to induce degradation of the LDL receptor (LDLR) in the lysosome of hepatocytes. Only in the last few years, a number of breakthroughs in the understanding of PCSK9 biology have been reported illustrating how PCSK9 activity is tightly regulated at several levels by factors influencing its transcription, secretion, or by extracellular inactivation and clearance...

There is uncertainty about the relation between blood pressure and vascular disease at older age. We assessed the association of systolic blood pressure (SBP) and major vascular events in a prospective cohort study of 7564 men aged 65 to 94 years, recruited in 1996-1999 from the general population in Perth, Western Australia. SBP was measured at baseline and again at resurvey in 2001-2004. Participants were monitored for fatal and nonfatal vascular events. To limit the effect of reverse causality, analyses were restricted to men without previous vascular disease at baseline...

We aimed to (1) investigate the relation between diuretic response (DR) with or without systemic congestion and prognosis and (2) explore the potential predictors of poor DR for risk stratification in patients with acute decompensated heart failure (ADHF). We enrolled 186 consecutive patients hospitalized for ADHF. The DR was defined as (body weight at discharge - body weight at admission)/40 mg furosemide or equivalent loop diuretic dose. Systemic congestion on admission was simply evaluated by the presence of leg edema or jugular venous distention...

Reactive oxygen and nitrogen species (ROS and RNS, e.g. H2O2, nitric oxide) confer redox regulation of essential cellular signaling pathways such as cell differentiation, proliferation, migration and apoptosis. At higher concentrations, ROS and RNS lead to oxidative stress and oxidative damage of biomolecules (e.g. via formation of peroxynitrite, fenton chemistry). Peripheral artery disease (PAD) is characterized by severe ischemic conditions in the periphery leading to intermittent claudication and critical limb ischemia (end stage)...

OBJECTIVES: Acute kidney injury (AKI) is defined as decrease in glomerular filtration rate with increase in serum creatinine (sCr). Perinatal asphyxia (PNA) may be an ethiological factor for AKI with oxidative stress also implicated. Paraoxonase 1 (PON1) has been reported to be decreased in renal diseases. The aim of our study was to evaluate paraoxonase 1 (PON1) and oxidative stress status, their change during the first hours and days of life and the ability of these parameters to discriminate neonates having AKI from those who do not have it...

BACKGROUND AND AIMS: Bone marrow (BM)-derived progenitor cells are functionally impaired in patients with ischemic heart disease (IHD), thereby hampering the outcome of autologous stem cell therapy. In search for underlying mechanisms for this BM dysfunction, accelerated cellular senescence was explored. METHODS: We analysed telomere length of BM-derived mononuclear cells (MNC) by MMqPCR in patients with coronary artery disease (n = 12), ischemic heart failure (HF; n = 9), non-ischemic HF (n = 7) and controls (n = 10), and related it to their myeloid differentiation capacity...

Since its discovery as a major CNS-abundant protein 25 years ago, Ubiquitin C-terminal hydrolase-L1 (UCH-L1) has emerged as an important enzyme in regulating brain protein metabolism, by coupling to the proteasome pathway of protein degradation. Areas covered: UCH-L1 is implicated in both familial and sporadic Parkinson disease and other chronic neurodegenerative diseases. Also, UCH-L1 has been recently emerging as a biofluid-based biomarker for various forms of acute neurotrauma and CNS injury. Expert opinion: The loss of UCH-L1 activity coupled with the gain of proteinopathy function are linked to neurodegeneration such as Parkinsonism and Alzheimer's disease...

This study was conducted to assess status, and understand burden, of premature and leading causes of deaths from noncommunicable diseases (NCDs) in the Federated States of Micronesia (FSM). From 2003 to 2012, ICD-10 coded mortality data from the national Health Information System were analyzed. Proportional mortality was calculated and a ranking list of the leading causes of premature death was produced. Of the 2349 premature deaths reported, 1970 (83.9%) were due to NCDs, and 1680 (71.5%) were from 4 main NCD groups-cardiovascular diseases, cancer, diabetes, and chronic respiratory diseases...

Esophageal cancer has a poor overall prognosis and is frequently diagnosed at a late stage. Conventional treatment for metastatic esophageal cancer involves chemotherapy and radiation. Local disease control plays a significant role in improving survival. Endoscopic spray cryotherapy is a novel modality that involves freezing and thawing to produce local ablation of malignant tissue via ischemic mechanisms. Spray cryotherapy has been shown to be effective, particularly for early T-stage, superficial esophageal adenocarcinomas...
