what causes renin-angiotensin system to be activated during compensation for heart failure?
Heart failure means that your heart muscle doesn't pump as much blood as your body needs. Because your heart cannot pump well, your heart and your body try to make up for it. This is called compensation. Your body has a remarkable ability to compensate for heart failure. The body may do such a good job that many people don't feel symptoms in the earlier stages of heart failure.
