BACKGROUND: Blockade of the renin-angiotensin system (RAS) represents a main strategy in the therapy of heart failure with reduced ejection fraction (HFrEF), but the role of active renin concentration (ARC) for guiding therapy in the presence of an RAS blockade remains to be established. This study assessed angiotensin profiles of HFrEF patients with distinct RAS activations as reflected by ARC. METHODS: Two cohorts of stable chronic HFrEF patients on optimal medical treatment (OMT) were enrolled...

BACKGROUND: The American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) was used to establish predictors for 30-day postoperative complications following spine and cranial neurosurgery. MATERIALS AND METHODS: The ACS-NSQIP participant use files were queried for neurosurgical cases between 2005 and 2015. Prevalence of postoperative complications following neurosurgery was determined. Nested multivariable logistic regression analysis was used to identify demographic, comorbidity, and perioperative characteristics associated with any complication and mortality for spine and cranial surgery...

BACKGROUND: Mineralocorticoid receptor (MR) antagonists are the recommended medical therapy for primary aldosteronism. Whether this recommendation effectively reduces cardiometabolic risk is not well understood. We aimed to investigate the risk of incident cardiovascular events in patients with primary aldosteronism treated with MR antagonists compared with patients with essential hypertension. METHODS: We did a cohort study using patients from a research registry from Brigham and Women's Hospital, Massachusetts General Hospital, and their affiliated partner hospitals...

The effect of early use of tolvaptan (TLV) for acute decompensated heart failure (ADHF) is unclear. We investigated the relationship between early use of TLV and the length of hospital stay. 369 consecutive ADHF patients who received TLV during hospitalization between February 2011 and June 2016 were initially enrolled. Patients who died in hospital, transferred hospital or clinical scenario 4 or 5 were excluded. We analyzed 247 ADHF patients. We evaluated the relationship between the length of hospital stay and the following findings: blood pressures, heart rate, New York Heart Association classification, and blood tests on admission...

BACKGROUND: It is unknown if normal findings on noninvasive cardiac assessment are able to identify individuals who are low risk for developing heart failure (HF). METHODS: We examined if normal findings on the routine electrocardiogram (ECG) and cardiac magnetic resonance imaging (MRI) were able to identify individuals who are low risk for developing HF in 4986 (mean age=62±10years; 52% women; 39% White; 13% Chinese-American; 26% Black; 22% Hispanic) participants from the Multi-Ethnic Study of Atherosclerosis who were free of clinically apparent HF at baseline...

With the adoption of the new definition and classification of cardiorenal syndrome (CRS) and its relevant subtypes, much attention has been placed on elucidating the mechanisms of heart and kidney interactions. The pathophysiologic pathways are of great interest by which acute heart failure may result in acute kidney injury (AKI; type 1), chronic heart failure accelerates the progression of chronic kidney disease (CKD; type 2), AKI provokes cardiac events (type 3), and CKD increases the risk and severity of cardiovascular disease (type 4)...

OBJECTIVES: To provide reference intervals for 2-dimensional linear and area-based estimates of left atrial (LA) function in healthy dogs and to evaluate the ability of estimates of LA function to differentiate dogs with subclinical myxomatous mitral valve disease (MMVD) and similarly affected dogs with congestive heart failure (CHF). ANIMALS: Fifty-two healthy adult dogs, 88 dogs with MMVD of varying severity. METHODS: Linear and area measurements from 2-dimensional echocardiographs in both right parasternal long and short axis views optimized for the left atrium were used to derive estimates of LA active emptying fraction, passive emptying fraction, expansion index, and total fractional emptying...

The limited myocardial fibre thickening and shortening alone cannot explain the marked left ventricular (LV) volume reduction during LV ejection. This can only be achieved with LV helical (spiral) orientation of myocardial fibres, which is determined by the non-contractile LV myocardial components (intrasarcomeric and extrasarcomeric cytoskeleton, extracellular matrix). Preservation of LV ejection fraction (LVEF) in heart failure (HF) is due to the presence of normal ellipsoid LV configuration and spiral myocardial fibre orientation...

OBJECTIVE: Cardiac disease is the leading cause of indirect maternal mortality. The aim of this study was to analyse to what extent socioeconomic factors influence the outcome of pregnancy in women with heart disease. METHODS: The Registry of Pregnancy and Cardiac disease is a global prospective registry. For this analysis, countries that enrolled ≥10 patients were included. A combined cardiac endpoint included maternal cardiac death, arrhythmia requiring treatment, heart failure, thromboembolic event, aortic dissection, endocarditis, acute coronary syndrome, hospitalisation for cardiac reason or intervention...

Background -Patients with congenital heart disease (CHD) are assumed to be vulnerable to atrial fibrillation (AF) due to residual shunts, anomalous vessel anatomy, progressive valvulopathy, hypertension, and atrial scars from previous heart surgery. However, the risk of developing AF as well as the complications associated with AF in children and young adults with CHD have not been compared with those in controls. Methods -Data from the Swedish Patient and Cause of Death Registers were used to identify all patients with a diagnosis of CHD who were born from 1970 to 1993...

Objective: To explore the impact of weight management and related medication intervention based on body weight changes on cardiac function among patients with chronic congestive heart failure (CHF). Methods: Using prospective, randomized, controlled study methods, consecutive CHF patients, who hospitalized in our department from June 2014 to June 2016 (n=350), were randomly divided into intervention group (n=175) and control group (n=175). Patients in the intervention group received weight management guidance and the post discharge diuretic drugs regimen was adjusted based on body weight changes...

Glaucoma (GL) and atrial fibrillation (AF) are diseases of significant social importance. Cardiovascular disorders such as systemic hypertension, hypotension, increased blood viscosity, vasospasm, and diabetes are potential risk factors of GL, especially when intraocular pressure is not elevated. Only a few studies have reported a possible connection between cardiac arrhythmias and GL. The purpose of this study was to evaluate the risk of GL in patients with AF.A total of 117 patients were included in the study, 79 with AF (AF group) and 38 with sinus rhythm (Control group), matched for age and sex...

Continuous monitoring of heart failure (HF) patients is desirable in order to better manage their illness and reduce unnecessary hospitalization. A comprehensive cloud-based HF patient management system is proposed to collect patients' health status information and provide just-in-time intervention. To date, an HF patient edema monitoring system prototype, including the device and its algorithm, has been developed. The hardware features multiple sensors whose data are fused using an edema classification algorithm based on a standard linear solid (SLS) edematous tissue model...

The aim of this work is to present a computational approach for the estimation of the severity of heart failure (HF) in terms of New York Heart Association (NYHA) class and the characterization of the status of the HF patients, during hospitalization, as acute, progressive or stable. The proposed method employs feature selection and classification techniques. However, it is differentiated from the methods reported in the literature since it exploits information that biomarkers fetch. The method is evaluated on a dataset of 29 patients, through a 10-fold-cross-validation approach...

Atrial Fibrillation (AF) is the most common arrhythmia and it is estimated to affect 33.5 million people worldwide. AF is associated with an increased risk of mortality and morbidity, such as heart failure and stroke and affects mostly older persons and persons with other conditions (e.g. heart failure and coronary artery disease). In order to prevent such life threatening and life quality reducing conditions it is essential to provide better algorithms, capable of being integrated in low-cost personalized health systems...

Atrial fibrillation (AF) is one of the major causes of stroke, heart failure, sudden death, and cardiovascular morbidity and the most common type of arrhythmia. Its diagnosis and the initiation of treatment, however, currently requires electrocardiogram (ECG)-based heart rhythm monitoring. The photoplethysmogram (PPG) offers an alternative method, which is convenient in terms of its recording and allows for self-monitoring, thus relieving clinical staff and enabling early AF diagnosis. We introduce a PPG-based AF detection algorithm using smartphones that has a low computational cost and low memory requirements...

Pulmonary hypertension (PH) is a pathophysiological disorder that may involve multiple clinical conditions characterizing with by an abnormal increase in mean pulmonary arterial pressure. It is a rare, debilitating disease with a poor prognosis. Despite significant progress in diagnosis and management, including disease-targeted therapies as well as development of specialized centres, PH remains a chronic disease without a cure. If untreated, it leads to right heart failure and premature death, and a multifactorial pathomechanism impacts negatively on further prognosis...
