Please guide Congestive heart failure.

Heart failure, sometimes known as congestive heart failure, occurs when your heart muscle doesn't pump blood as well as it should. Certain conditions, such as narrowed arteries in your heart (coronary artery disease) or high blood pressure, gradually leave your heart too weak or stiff to fill and pump efficiently.
 
Treatment
  1. Vasodilators expand blood vessels, ease blood flow, and reduce blood pressure.
  2. Diuretics correct fluid retention.
  3. Aldosterone inhibitors help with fluid retention and improve chances of living longer.
  4. ACE inhibitors or ARB drugs improve heart function and life expectancy.
 
The current in-hospital treatment for CHF involves removal of excess fluid with diuretic medication and/or ultrafiltration in which a machine bypasses the kidneys and filters water and salt from the body. However, these treatments can have unwanted side effects such as low blood pressure and worsening kidney function.
 
In more than half of all people with heart disease, death follows within an hour of an attack, as the heart stops pumping blood, and hence oxygen, to the brain. But chronic congestive heart failure brings a slower, more painful death.
