Parâmetros clínicos e ecocardiográficos associados a baixo índice cronotrópico em pacientes não idosos Clinical and echocardiographic parameters associated with low chronotropic index in non-elderly patients

open access: yesArquivos Brasileiros de Cardiologia, 2012
FUNDAMENTO: Apesar das inúmeras evidências de aumento da morbimortalidade, a incompetência cronotrópica (IC) ainda não é um diagnóstico rotineiro e bem definido nos protocolos de avaliação cardiológica e sua importância clínica ainda é subestimada ...

Initial experience using contrast enhanced real-time three-dimensional exercise stress echocardiography in a low-risk population

open access: yesHeart International, 2010
Although emerging data support the utility of real-time three-dimensional echocardiography (RT3DE) during dobutamine stress testing, the feasibility of performing contrast enhanced RT3DE during exercise treadmill stress has not been explored.

ABCDEG Stress Echocardiography in Aortic Stenosis

open access: yesDiagnostics, 2023
Rest and stress echocardiography (SE) plays a pivotal role in the evaluation of valvular heart disease. The use of SE is recommended in valvular heart disease when there is a mismatch between resting transthoracic echocardiography findings and symptoms ...

Nebulette knockout mice have normal cardiac function, but show Z-line widening and up-regulation of cardiac stress markers [PDF]

open access: yes, 2015
Aims: Nebulette is a 109 kDa modular protein localized in the sarcomeric Z-line of the heart. In vitro studies have suggested a role of nebulette in stabilizing the thin filament, and missense mutations in the nebulette gene were recently shown to be ...

A Soft Robotic Model for Simulating Heart Valve Disease and Cardiac Interventions

open access: yesAdvanced Science, EarlyView.
This paper introduces a fully synthetic fabrication methodology for a soft robotic, in‐vitro model of the left‐heart, complete with a functioning mitral valve apparatus. With a view towards patient‐specific modeling, we demonstrate physiological flow and pressure waveforms, tunable mitral valve function with clinical imaging compatibility, and its use ...

Silencing of the Na+/H+ exchanger 1(NHE-1) prevents cardiac structural and functional remodeling induced by angiotensin II [PDF]

open access: yes, 2019
Chronic activation of the renin angiotensin system (RAS) favors several cardiac diseases, among which myocardial hypertrophy occupies an outstanding place. In this context, the hyperactivity of the cardiac Na+/H+ (NHE-1) exchanger plays a key role.

Oral Bioinspired Peroxisome‐Engineered Probiotics for Modulating Gut Microbiota Homeostasis and Alleviating Cardiac Chemotherapy Toxicity

open access: yesAdvanced Science, EarlyView.
This study developed an oral bioinspired peroxisome‐engineered probiotic (BPEP) by anchoring lipid‐encapsulated ruthenium nanozymes onto Escherichia coli Nissle 1917, utilizing probiotics to deliver nanozymes to the intestinal barrier for reactive oxygen species/reactive nitrogen species elimination, tight junction restoration, and gut microbiota ...

Factors associated with cardiovascular events after simultaneous liver–kidney transplant from the US Multicenter Simultaneous Liver–Kidney Transplant Consortium

open access: yesHepatology Communications, EarlyView., 2022
Abstract Cardiovascular disease is a leading complication after both liver and kidney transplantation. Factors associated with and rates of cardiovascular events (CVEs) after simultaneous liver–kidney transplant (SLKT) are unknown. This was a retrospective cohort study of adult SLKT recipients between 2002 and 2017 at six centers in six United Network ...

Cardiac magnetic resonance findings predict increased resource utilization in elective coronary artery bypass grafting [PDF]

open access: yes, 2008
Morbidity following CABG (coronary artery bypass grafting) is difficult to predict and leads to increased healthcare costs. We hypothesized that pre-operative CMR (cardiac magnetic resonance) findings would predict resource utilization in elective CABG ...
