BACKGROUND: Stable plasma nitric oxide (NO) metabolites (NOM), composed predominantly of nitrate and nitrite, are attractive biomarkers of NO bioavailability. NOM levels integrate the influence of NO-synthase-derived NO production/metabolism, dietary intake of inorganic nitrate/nitrite, and clearance of NOM. Furthermore, nitrate and nitrite, the most abundant NOM, can be reduced to NO via the nitrate-nitrite-NO pathway. METHODS AND RESULTS: We compared serum NOM among subjects without heart failure (n=126), subjects with heart failure and preserved ejection fraction (HFpEF; n=43), and subjects with heart failure and reduced ejection fraction (HFrEF; n=32)...

Ivabradine is a blocker of the funny current channels in the sinoatrial node cells. This results in pure heart rate reduction when elevated without direct effect on contractility or on the vessels. It was tested in a large outcome clinical trial in stable chronic heart failure (CHF) with low ejection fraction, in sinus rhythm, on a contemporary background therapy including betablockers (SHIFT: Systolic Heart Failure Treatment with the If inhibitor Trial).The primary composite endpoint (cardiovascular mortality or heart failure hospitalization) was reduced by 18% whereas the first occurrence of heart failure hospitalizations was reduced by 26%...

Heart transplantation (HT) recipients may have tachycardia secondary to cardiac denervation. As higher heart rate predicts worse outcomes in cardiovascular disease, we hypothesized that tachycardia and nonuse of β blockers are associated with increased mortality after HT. All patients who underwent HT at our institution from 1987 to 2010 were included. The association of heart rate 3 months after HT and β-blocker use during follow-up to mortality was assessed using Kaplan-Meier and multivariate Cox proportional hazards regression analyses adjusting for clinically relevant baseline variables...

PURPOSE: For circulatory support, venoarterial extracorporeal membrane oxygenation (VA-ECMO) is dependent on sufficient venous drainage ensured by fluid therapy. Volume overload however is linked to poor prognosis. This study therefore evaluates volume therapy in VA-ECMO. MATERIAL AND METHODS: We report data of a single center registry of all patients after VA-ECMO implantation treated between 2010 and 2015. RESULTS: A total of 195 patients were included in this registry with a medium age of 58...

BACKGROUND: Severe arrhythmias or heart failure may be surrogates of myocardial involvement in patients with connective tissue disorders (CTD). However, most patients present with unspecific symptoms, normal ECG, and preserved left ventricular ejection fraction (LV-EF). Therefore, timely diagnosis by an accurate technique is crucial. Late gadolinium enhancement (LGE) cardiovascular magnetic resonance (CMR) has proven value for the detection of focal processes, but due to the often diffuse character of fibrosis/inflammation in CTD patients, CMR mapping techniques might be of incremental value for the assessment of myocardial involvement...

BACKGROUND: Older adults with chronic disease struggle to manage complex medication regimens. Health information technology has the potential to improve medication management, but only if it is based on a thorough understanding of the complexity of medication management workflow as it occurs in natural settings. Prior research reveals that patient work related to medication management is complex, cognitive, and collaborative. Macrocognitive processes are theorized as how people individually and collaboratively think in complex, adaptive, and messy nonlaboratory settings supported by artifacts...

Chronic thromboembolic pulmonary hypertension (CTEPH) is precapillary pulmonary hypertension, in which chronic obstruction of large and middle branches of pulmonary arteries (PAs) and secondary changes in the lung microcirculatory bed result in a progressive increase in pulmonary vascular resistance and PA pressure with the development of severe right cardiac dysfunction and heart failure. CTEPH is a unique form of pulmonary hypertension since it is potentially curable by surgical treatment. The diagnostic criteria for CTEPH are a mean PA pressure of ≥25 mm Hg, as evidenced by right heart catheterization; a PA wedge pressure of ≤15 mm Hg; a pulmonary vascular resistance of >2 Wood units; the presence of chronic/organized thrombi/emboli in the elastic PAs (pulmonary trunk, lobular, segmental, subsegmental PAs); effective anticoagulant therapy at therapeutic dosages over at least 3 months...

Dilated cardiomyopathy is a rare cardiac disease characterized by left ventricular dilatation and systolic dysfunction leading to heart failure and sudden cardiac death. Currently, despite several conditions have been reported as aetiologies of the disease, a large number of cases remain classified as idiopathic. Recent studies determine that nearly 60% of cases are inherited, therefore due to a genetic cause. Progressive technological advances in genetic analysis have identified over 60 genes associated with this entity, being TTN the main gene, so far...

Effective combination antiretroviral therapy (ART) has enabled human immunodeficiency virus (HIV) infection to evolve from a generally fatal condition to a manageable chronic disease. This transition began two decades ago in high-income countries and has more recently begun in lower income, HIV endemic countries (HIV-ECs). With this transition, there has been a concurrent shift in clinical and public health burden from AIDS-related complications and opportunistic infections to those associated with well-controlled HIV disease, including cardiovascular disease (CVD)...

Cardiac involvement of sarcoid lesions is diagnosed by myocardial biopsy which is frequently false-negative, and patients with cardiac sarcoidosis (CS) who have impaired left ventricular (LV) systolic function are sometimes diagnosed with dilated cardiomyopathy (DCM). Late gadolinium enhancement (LE) in magnetic resonance imaging is now a critical finding in diagnosing CS, and the novel Japanese guideline considers myocardial LE to be a major criterion of CS. This article describes the value of LE in patients with CS who have impaired LV systolic function, particularly the diagnostic and clinical significance of LE distribution in comparison with DCM...

AIMS: Previous studies revealed that patients with Takotsubo cardiomyopathy (TTC) have a higher mortality rate than the general population. Supraventricular tachycardia is a well-known complication of TTC. This study was performed to determine the short- and long-term prognostic impact of atrial fibrillation associated with TTC patients. METHODS AND RESULTS: Our institutional database constituted a collective of 114 patients diagnosed with TTC from 2003 to 2015...

BACKGROUND: Recent studies demonstrated that oral anticoagulants (OACs) should be considered for patients with atrial fibrillation and 1 risk factor in addition to sex. Because age is an important determinant of ischemic stroke, the strategy for stroke prevention may be different for these patients in different age strata. The aim of this study was to investigate whether OACs should be considered for patients aged 20 to 49 years with atrial fibrillation and a CHA2DS2-VASc score of 1 (men) or 2 (women)...

BACKGROUND: Platelets' role in pathophysiology of acute coronary syndromes (ACS) is undeniable, but precise relationships between platelet activity and treatment outcomes are matter of continuant investigation. Among platelet indices, mean platelet volume (MPV) has proven to be valuable predicting factor in cardiac patients. However platelet distribution width (PDW) is reported to be more specific marker of platelet reactivity. Thus, application of PDW in risk stratification of ACS treatment is up-to-date subject of research...

We describe a new type of cardiomyopathy caused by a mutation in the glycogenin-1 gene (GYG1). Three unrelated male patients aged 34 to 52 years with cardiomyopathy and abnormal glycogen storage on endomyocardial biopsy were homozygous for the missense mutation p.Asp102His in GYG1. The mutated glycogenin-1 protein was expressed in cardiac tissue but had lost its ability to autoglucosylate as demonstrated by an in vitro assay and western blot analysis. It was therefore unable to form the primer for normal glycogen synthesis...
