Does the heart deteriorate very vast in acromegalic patient , or take long time till the heart manifest some problem ? in my case , i have normal echocardiography expect mild aortic regurgitation and mild tricuspid regurgitation, thx in advance?

The doctor who can likely answer this question in your case would be your endocrinologist. The treatment you are receiving will likely impact the speed at which any heart damage would occur. You should be under the care of an endocrinologist and that doctor should be treating your condition. The treatment will affect progression so the endocrinologist treating you can give you the expectations.
