Myocardial Mechanical Function in Heart Failure: How Should We Think About It and Measure It?

  • M. I. Noble
Part of the Update in Intensive Care and Emergency Medicine book series (UICM, volume 6)


The purpose of this chapter is to present a conceptual framework of mechanical myocardial events taking place in heart failure. We need clear definitions of the various types of heart failure: and first the congestive syndrome. This is raised systemic venous pressure, edema, raised blood volume, extracellular fluid volume and exchangeable sodium. It is caused by sodium and water retention by the kidneys due to renal, liver, lung or heart disease and is reversed by diuretics. It is subacute or chronic because sodium and water retention by the kidneys takes time to produce a raised venous pressure [1].
