was the death preventable.

He was suffering from unstable angina. Heart failure. Received all medications as advised by cardiologists and Physicians. The next thing  possible was angioplasty which was too risky in this age. I am mentally shattered. All people are saying this thing is to continue for two months atleast. My father died at the age of 89, in active state, nothing can be better than this. Everybody is destined to die. I am totaly shocked but I must get over it. This is part of life. I am a doctor, so I believe that I could have saved him. Good joke!
