Hello, Heart function is weak and one can live good life with this amount of function.  You should have a healthy lifestyle like avoiding fatty, oily and high calorie diet. Have low salt diet and monitor blood pressure regularly. Regular exercises like brisk walking, jogging according your capacity at least 30 min a day and 5 days a week. Lots of green leafy vegetables, fruits, fish once or twice a week, avoid meat. Avoid smoking and alcohol if any.  Make sure you are receiving antiplatelet like Aspirin clopidogrel, statins like Atorvastatin, beta blockers, ace inhibitor like April and spironolactone, which will prevent further decline of heart function. Hope this helps you and get back if you have any doubts.
