Application of NASTRAN for stress analysis of left ventricle of the heart [PDF]

, 1975
Knowing the stress and strain distributions in the left ventricular wall of the heart is a prerequisite for the determination of the muscle elasticity and contractility in the process of assessing the functional status of the heart.

Ca2+/calmodulin‐dependent protein kinase II and protein kinase G independently contribute to acutely enhance myocardial compliance with stretch

Physiological Reports
The heart constantly adapts to acute hemodynamic load by increasing contractility and stretch‐induced compliance (SIC). The latter involves titin phosphorylation, notably by cGMP‐dependent protein kinase (PKG).

Insuficiência cardíaca com fração de ejeção normal Insuficiencia cardíaca con fracción de eyección normal Heart failure with normal ejection fraction

Arquivos Brasileiros de Cardiologia, 2010
A insuficiência cardíaca com fração de ejeção normal (ICFEN) é uma síndrome complexa que vem sendo largamente estudada, desde a última década. É causada por disfunção ventricular diastólica evidenciada por métodos complementares, como estudo hemodinâmico
