My dad, age 69 was operated for Angioplasty in 1999. He was doing well with proper medicines & regular check ups until recently, when he complained of some cough & stomach pain (moreover tightness). After being admitted doctors have confirmed problem with liver & low heart functioning (they say 15%)...
How is this 15% measured? Can we improve upon this? How many years can a patient live with 10-15% heart function? How to handle such patients in terms of exrercise, medication, daily routine, etc.
