- EF = 27%
- from July 2007, i have stoped smoke + alcohol intake
- i was put on coversyl ( to lower my BP ) + Burnex ( to get rid of excess fluid ) + Vastarel MR + Marivan ( anti thrombi )
- Till a month ago my EF showed no change
- I visited another doctor who put me on :
   * Lanoxin ( digoxin )
   * Capoten
