These include the Frank-Starling mechanism, changes in myocyte regeneration, myocardial hypertrophy, and myocardial hypercontractility.
WebSummary. The Frank–Starling law (also known as Starling’s law of the heart) states that the strength of ventricular contraction is dependent on the length of the resting fibres. In other words, when all other factors are kept constant, an increase in left ventricular preload causes stroke volume (SV) to increase, without the need for ... WebIn chronic heart failure, various regulatory systems including the Frank-Starling mechanism, the neuro-hormonal response, cardiac growth and peripheral oxygen delivery may be operative. Recently, the inter-relationship of the renin-angiotensin-aldosterone system (RAAS) and cardiac growth has drawn clinical interest.
