NR 507 Week 3 Discussion Question: Congestive Heart Failure WITH CORRECT RESEARCH ANSWERS AND GUARANTEED GRADE A+ SCORE In heart failure, the heart is unable to produce enough cardiac output to pe... rfuse and supply the body with its needs. To fix this, the body works to compensate by activating a defense mechanism in order to fulfil the demands. Gordin and Fonarow (2016) explained that it does so by activating reactions in the body’s neural and hormonal systems, including the Renin Angiotensin Aldosterone system (RAA). The authors detailed that lack of perfusion to the kidneys causes the body’s renin levels to increase; After renin converts Angiotensinogen to Angiotensin I and further to Angiotensin II, the body goes through the process of vasoconstriction, causing the release of Antidiuretic Hormone (ADH) and Aldosterone, which further releases catecholamines. The authors further explained that as this process continues for longer periods of time, the ventricles begin to remodel and become fibrotic, cardiac output is released and fluid builds up causing volume overload.
