It can also be a result of having abnormal heart valves, a heart muscle disease like cardiomyopathy, presence of a congenital heart disease, severe lung disease, diabetes, and obesity (CITE). It is characterized by the stimulation of multiple compensatory mechanisms that’s main purpose is to increase cardiac output. The heart is unable to maintain sufficient oxygenation and has to compensate in order to rectify this inadequacy. The body can’t function in this compensatory state for long, and eventually they fail causing long term negative effects. The two mechanisms that are activated include the sympathetic nervous system and the renin angiotensin aldosterone system. Our current medical regime for treatment is intended to reduce the activity of both of these
