Background: Fluid overload and interdialytic weight gain (IDWG) are discrete components of the dynamic fluid balance in haemodialysis patients. We aimed to disentangle their relationship, and the prognostic importance of two clinically distinct, bioimpedance spectroscopy (BIS)-derived measures, pre-dialysis and post-dialysis fluid overload (FOpre and FOpost) versus IDWG. Methods: We conducted a retrospective cohort study on 38 614 incident patients with one or more BIS measurement within 90 days of haemodialysis initiation (1 October 2010 through 28 February 2015)...

PURPOSE: The infrapatellar fat pad (IFP) is a common cause of knee pain and loss of knee flexion and extension. However, its anatomy and behavior are not consistently defined. METHODS: Thirty-six unpaired fresh frozen knees (median age 34 years, range 21-68) were dissected, and IFP attachments and volume measured. The rectus femoris was elevated, suprapatellar pouch opened and videos recorded looking inferiorly along the femoral shaft at the IFP as the knee was flexed...

Relative blood volume (RBV) monitoring during hemodialysis has been used to help guide fluid management for decades, although with little supporting evidence. The technique relies on the assumption that variation in RBV during fluid removal reflects the capacity for vascular refilling and that efficient refilling is related to fluid overload. This study investigated the relationship between RBV variation and bioimpedance-based fluid overload in 47 patients on stable hemodialysis. Mean treatment ultrafiltration volume (UFV) was 1...

We have previously demonstrated that adult transgenic C57BL/6J mice with CM-restricted overexpression of the dominant negative W v mutant protein (dn-c-kit-Tg) respond to pressure overload with robust cardiomyocyte (CM) cell cycle entry. Here, we tested if outcomes after myocardial infarction (MI) due to coronary artery ligation are improved in this transgenic model. Compared to non-transgenic littermates (NTLs), adult male dn-c-kit-Tg mice displayed CM hypertrophy and concentric left ventricular (LV) hypertrophy in the absence of an increase in workload...

AIM: PDE5A is a leading factor contributing to cGMP signaling and cardiac hypertrophy. However, microRNA-mediated posttranscriptional regulation of PDE5A has not been reported. The aim of this study is to screen the microRNAs that are able to regulate PDE5A and explore the function of the microRNAs in cardiac hypertrophy and remodeling. METHODS AND RESULTS: Although miR-19a/b-3p (microRNA-19a-3p and microRNA-19b-3p) have been reported to be differentially expressed during cardiac hypertrophy, the direct targets and the functions of this microRNA family for regulation of cardiac hypertrophy have not yet been investigated...

BACKGROUND: In severe aortic stenosis, different left ventricle (LV) remodeling patterns as a response to pressure overload have distinct hemodynamic profiles, cardiac function, and outcomes. The most common classification considers LV relative wall thickness and LV mass index to create 4 different groups. A new classification including also end-diastolic volume index has been recently proposed. AIM: To describe the prevalence of the newly identified remodeling patterns in patients with severe aortic stenosis and to evaluate their clinical relevance according to symptoms...

BACKGROUND: Cocaine use has a high prevalence in the United States and can be associated with significant cardiovascular disease, even in asymptomatic users. β-Adrenergic receptor hyperactivation is the underlying pathophysiologic pathway of cocaine cardiotoxicity. β-Blocker therapy is controversial in patients with active cocaine use. HYPOTHESIS: β-Blocker therapy is associated with clinical improvement in patients with heart failure despite active cocaine use...

Type 1 diabetes mellitus is a difficult disease to treat due to the relative paucity of therapeutic options other than injectable insulin. The latter, however, can induce hypoglycemia, which has been linked to enhanced cardiovascular risk. Sodium glucose cotransporter 2 (SGLT2) inhibitors are a new class of oral anti-hyperglycemic medications that do not increase the hypoglycemia risk and are US Food and Drug Administration (FDA) approved in type 2 diabetes mellitus. SGLT2 inhibitors may also be of benefit in type 1 diabetic patients, in addition to insulin, although they have not yet been approved for this indication...

Heart failure (HF), characterized by excessive exertional dyspnea, is a common complication within the broad clinical spectrum of hypertrophic cardiomyopathy (HCM). HF has become an increasingly prominent management issue with the reduction in sudden deaths due to use of implantable defibrillators in this disease. Exertional dyspnea ranges in severity from mild to severe (New York Heart Association functional classes II to IV) and not uncommonly becomes refractory to medical management, leading to progressive disability, but largely in the absence of pulmonary congestion and volume overload requiring hospitalization...

Volume overload is an important, may be the foremost, independent prognostic factor determining the outcome of hemodialysis patients. Therefore, it is crucial to measure fluid status of these patients and avoid volume overload. This review aims to evaluate volume overload, its effects on patients with renal diseases and current methodologies measuring volume status in the body. These techniques will be first classified as clinical evaluation and non-clinical and/or instrumental techniques, which includes biomarkers, ultrasonography, relative blood volume monitoring, bioimpedance, echocardiography, pulmonary artery catheterization, esophageal and/or suprasternal Doppler, and blood viscosity...

Tricuspid regurgitation (TR) is a common valvular lesion which may affect morbidity and mortality. It can be related to an intrinsic abnormality of the tricuspid valve leaflets (organic) or secondary to annular dilatation (functional). Often organic and functional TR coexist in the same patient. A long standing TR is associated with ascites, congestive hepatopathy, peripheral edema, renal failure, and abdominal fullness which significantly affect the outcome. In particular, the perioperative course may be complicated due to both the presence of comorbidities and the development of a severe postoperative right ventricle (RV) dysfunction...

Currently, there is no consensus about the optimum intraoperative fluid therapy strategy. There is growing body of evidence supports the beneficial effects of adopting "Goal-directed therapy" over either the "liberal" or "restrictive" fluid therapy strategies. In this narrative review, we have presented the evidence to support the optimum strategy for intraoperative therapy. In conclusion, whatever the intravenous fluid replacement strategy used, the anesthesiologist must be prepared to adjust the composition and rate of the fluids administered to provide sufficient intravascular fluid volume for adequate perfusion of vital organs without overwhelming the glycocalyx function with fluid overloads...

Acute heart failure is a common complication of chronic heart failure and is associated with a high risk for subsequent mortality and morbidity. In 90% of case acute heart failure is the resultant of congestion, a manifestation of fluid build-up due to increased filling pressures. As residual congestion at discharge following an acute heart failure episodes is one of the strongest predictors of poor outcome, the goal of therapy should be to resolve congestion completely. Important to comprehend is that increased cardiovascular filling pressures are not solely the resultant of intravascular volume excess but can also be induced by a decreased venous capacitance...

Mitral valve regurgitation (MR) is the most common valvular heart disease. Primary MR is a disease of the mitral valve apparatus, whereas secondary MR is a disease of the left ventricle. Diagnosing and managing MR is often challenging and requires a structured approach, integrating findings on history, physical examination, and imaging. Decisions regarding treatment depend on knowledge of the etiology, natural history, and outcome of interventions for these patients with mitral valve disease. The optimal timing of intervention requires a comprehensive 2-dimensional and Doppler echocardiogram in each patient to determine the cause of the mitral valve disease, the severity of the regurgitation, and the effect of the volume overload on the left ventricle, as well as determining if a durable valve repair can be performed...

BACKGROUND: Volume overload in patients on hemodialysis (HD) is an independent risk factor for cardiovascular mortality. B-lines detected on lung ultrasound (BLUS) assess extravascular lung water. This raises interest in its utility for assessing volume status and cardiovascular outcomes. METHODS: End-stage renal disease patients on HD at the Island Rehab Center being older than 18 years were screened. Patients achieving their dry weight (DW) had a lung ultrasound in a supine position...

Diffuse myocardial fibrosis is a key pathophysiologic feature in heart failure and can be quantified by cardiac magnetic resonance (CMR) T1 mapping. However, increases in myocardial free water also prolong native T1 times and may impact fibrosis quantification. Thus far, the impact of systemic patient volume status remains unclear. In this study, native T1 time by CMR was investigated in hemodialysis (HD) patients (n = 37) and compared with healthy controls (n = 35). Volume status was quantified by bioimpedance spectroscopy and correlated with CMR T1 time...

BACKGROUND: Children with chronic kidney disease (CKD) have increased cardiovascular mortality. Identifying high-risk children who may benefit from further therapeutic intervention is difficult as cardiovascular abnormalities are subtle. Although transthoracic echocardiography may be used to detect sub-clinical abnormalities, it has well-known problems with reproducibility that limit its ability to accurately detect these changes. Cardiovascular magnetic resonance (CMR) is the reference standard method for assessing blood flow, cardiac structure and function...

BACKGROUND: Evidence indicates favorable effects of dialysate (DNa+ ) to serum sodium concentration (SNa+ ) alignment, however, results from larger sample populations are needed. For this reason, we conducted a retrospective propensity score-matched cohort study from a quality improvement project to investigate the effects of alignment on population of maintenance hemodialysis patients. METHODS: At 4 participating hemodialysis (HD) clinics, patients with SNa+ lower than the standard DNa+ of 137 mEq/L who received HD with DNa+ aligned to the average of the last 4 SNa+ measurements were evaluated (clinicaltrials...
