Insuficiência cardíaca com fração de ejeção normal: novos critérios diagnósticos e avanços fisiopatológicos Insuficiencia cardiaca con fracción de eyección normal: nuevos criterios diagnósticos y avances fisiopatológicos Heart failure with normal ejection fraction: new diagnostic criteria and pathophysiological advances

Arquivos Brasileiros de Cardiologia, 2009
A insuficiência cardíaca (IC) é uma complexa síndrome cardiovascular com elevada prevalência, sendo que seu quadro clínico frequentemente é associado à dilatação do ventrículo, à diminuição da contratilidade e à reduzida fração de ejeção do ventrículo ...

Changes in left ventricular electromechanical relations during targeted hypothermia

Intensive Care Medicine Experimental, 2020
Background Targeted hypothermia, as used after cardiac arrest, increases electrical and mechanical systolic duration. Differences in duration of electrical and mechanical systole are correlated to ventricular arrhythmias.

Cyclic Mechanical Loading of Cardiomyocytes via Pressure‐Driven Non‐Planar Membrane Deformation in a Bioreactor System

Advanced Science, EarlyView.
In this research article, Mansoor and coworkers present a novel device that applies controlled mechanical stimuli to cardiomyocytes using pressure‐driven membrane deformation. By exposing cells to physiologically and pathologically relevant loading conditions, the platform reproduces distinct structural, functional and molecular responses associated ...

Celastrol‐Loaded Conductive Hydrogel Mitigates Myocardial Ischemia‐Reperfusion Injury and Restores Electrophysiological Function

Advanced Science, EarlyView.
Schematic illustration of the Pluronic F127 diacrylate/gelatin methacryloyl/poly(3,4‐ethylenedioxythiophene):poly(styrenesulfonate)/celastrol hydrogel (FGPC) for localized myocardial ischemia–reperfusion injury treatment. FGPC combines sustained celastrol delivery with PEDOT:PSS‐mediated conductive support to attenuate acute oxidative/inflammatory ...
