BACKGROUND: The prevalence of hypothyroidism is high in hemodialysis (HD) patients and hypothyroidism increases all-cause mortality in HD patients. Comorbidities are common in HD patients and are associated with both mortality and hypothyroidism. The aim of the study is to explore the effect of the interactions of comorbidities and hypothyroidism on all-cause mortality in HD patients. METHOD: Patients with hypothyroidism (ICD-9-CM 244.0, 244.1, and 244.9) and matched patients without hypothyroidism in the Registry for Catastrophic Illness Patient Database of Taiwan Health Insurance from 2000 to 2010 were analyzed...

Despite the availability of a number of different classes of therapeutic agents with proven efficacy in heart failure, the clinical course of heart failure patients is characterized by a reduction in life expectancy, a progressive decline in health-related quality of life and functional status, as well as a high risk of hospitalization. New approaches are needed to address the unmet medical needs of this patient population. The European Medicines Agency (EMA) is undertaking a revision of its Guideline on Clinical Investigation of Medicinal Products for the Treatment of Chronic Heart Failure...

BACKGROUND: Enalapril (EPL) is an angiotensin-converting enzyme inhibitor for the treatment of hypertension and chronic heart failure. Enalaprilat (EPLT) is an active metabolite that contributes to the overall activity of EPL. AIM: To quantitate EPL along with its metabolite EPLT using LC-MS/MS, a bioanalytical method was developed and validated with tolbutamide in human plasma using a protein precipitation technique. RESULTS: The sensitive and selective method has an LLOQ of 1 ng/ml with a linearity range of 1-500 ng/ml for both EPL and EPLT using 300 µl of plasma without any matrix effect...

Diabetic cardiomyopathy is a chronic and irreversible heart complication in diabetic patients, and is characterized by complex pathophysiologic events including early diastolic dysfunction, cardiac hypertrophy, ventricular dilation and systolic dysfunction, eventually resulting in heart failure. Despite these characteristics, the underlying mechanisms leading to diabetic cardiomyopathy are still elusive. Recent studies have implicated microRNA, a small and highly conserved non-coding RNA molecule, in the etiology of diabetes and its complications, suggesting a potentially novel approach for the diagnosis and treatment of diabetic cardiomyopathy...

The adenosine A2B receptor (A2BAR) has been identified as an important therapeutic target in cardiovascular disease, however in vitro and in vivo targeting has been limited by the paucity of pharmacological tools, particularly potent agonists. Interestingly, 2-((6-amino-3,5-dicyano-4-(4-(cyclopropylmethoxy)phenyl)-2-pyridinyl)thio)acetamide (BAY60-6583), a potent and subtype-selective A2BAR agonist, has the same core structure as 2-amino-6-[[2-(4-chlorophenyl)-1,3-thiazol-4-yl]methylsulfanyl]-4-[4-(2-hydroxyethoxy)phenyl]pyridine-3,5-dicarbonitril (capadenoson)...

BACKGROUND: Heart failure has the highest rates of adult hospitalisations, the highest mortality rates and significant costs associated with its care. The cost of heart failure is expected continue to grow on a global scale, with $108 billion spent on heart failure in 2012. Mortality rates are high, with incident cases of heart failure resulting in 30% 1-year mortality, and in hospital mortality of acute heart failure, 28%. METHODS AND RESULTS: This article reviews the devices currently in use for the treatment of heart failure, as well as those that are under investigation...

BACKGROUND: Chronic kidney disease (CKD) is a known predictor for adverse outcomes in patients with advanced heart failure requiring left ventricular assist devices (LVADs). The effect of pre-LVAD glomerular filtration rate (GFR) on post-LVAD outcomes in CKD patients is not completely understood. Additionally, a subset of patients improve their GFR after LVAD placement. In this study we sought to determine the effects of pre-LVAD GFR on post-LVAD outcomes. METHODS: Two hundred and seventy consecutive patients with LVADs were enrolled...

BACKGROUND: In patients with chronic heart failure (CHF) increasing levels of total serum cholesterol are associated with improved survival - while statin usage is not. The impact of statin treatment on the "reverse epidemiology" of cholesterol is unclear. METHODS: 2992 consecutive patients with non-ischemic CHF due to left ventricular systolic dysfunction from the Norwegian CHF Registry and the CHF Registries of the Universities of Hull, UK, and Heidelberg, Germany, were studied...

BACKGROUND: We and others have previously reported that the Great East Japan Earthquake (GEJE) caused a significant but transient increase in cardiovascular diseases and deaths in the disaster area. However, it remains to be examined whether the GEJE had a long-term prognostic influence in large-scale cohort studies. This point is important when analyzing the data before and after the GEJE in the cohort studies in the disaster area. METHODS: We examined 8676 patients registered in our Chronic Heart Failure Analysis and Registry in the Tohoku District-2 (CHART-2) Study (N=10,219) between 2006 and 2010 and were alive after March 10, 2011...

Female gender, post-menopause, chronic kidney disease (CKD) and (CKD linked) microvascular disease are important risk factors for developing heart failure with preserved ejection fraction (HFpEF). Enhancing our understanding of the interrelation between these risk factors could greatly benefit the identification of new drug targets for future therapy. This review discusses the evidence for the protective role of estradiol (E2) in CKD-associated microvascular disease and related HFpEF. Elevated circulating levels of uremic toxins (UTs) during CKD may act in synergy with hormonal changes during post-menopause and could lead to coronary microvascular endothelial dysfunction in HFpEF...

It is now well established that the NO-sGC-cGMP signal transduction system mediates many different physiological functions in almost every conceivable organ system; this has been best characterized in the cardiovascular system where NO-driven cGMP production exerts a plethora of cytoprotective and anti-atherogenic effects, including dilatation, inhibition of vascular smooth muscle proliferation, blockade of leukocyte recruitment, and anti-platelet activity. Accordingly, dysfunctional NO-sGC-cGMP mediated signaling is perceived as the underlying pathophysiological cause of many cardiovascular and non-cardiovascular diseases...

Diabetes mellitus (DM), a chronic metabolic disease characterized by hyperglycemia, is a profound cardiovascular (CV) risk factor. It compounds the effects of all other risk factors, leads to premature micro- and macrovascular disease, facilitates development of heart failure, worsens the clinical course of all CV diseases, and shortens life expectancy. Established DM, unrecognized DM, and dysglycemia that may progress to DM are all commonly present at the time of presentation of overt CV disease. Thus, CV specialists and trainees frequently treat patients with dysglycemia...

Accumulating evidence from mainly uncontrolled clinical studies with various types of ablation catheters have shown that renal denervation (RDN) can be applied safely and is effective in lowering blood pressure (BP) in patients with treatment-resistant hypertension. Sustained BP lowering has been documented up to 3 years. Furthermore, RDN has been associated with regression of target organ damage, such as left ventricular hypertrophy, arterial stiffness, and others. Several studies indicate potential benefit in other common clinical conditions associated with increased sympathetic tone including chronic kidney disease and heart failure...
