Hello, hope everyone with theses problems are getting better. My sister had heart bypass surgery on April 4th 2008, since then she has been back to the hospital 3 times...she had 6 bypasses, suffered mild stroke, and has had tubes in her lungs for 1 month and a few days, she went back to the hospital yesterday, with trouble breathing, and she had a cat scan, and they have found a blood clot on her lungs, dont know yet if it only one or more...she has really been though the mill, with this surgery, I dont understand why some people have so much trouble, and then others recovery is so great, I am worried..it seems like everything that can go wrong, is doing just that, she is so stressed and tired. I have been staying with her most days, and i keep trying to tell her to fight it...and then mess like this happens, has anyone been though all this from having heart surgery. she is also a diabetic, and blood pressure problems, someone stated that if the tubes were in the lungs for more than 7 days there will be a infection, could she have a infection which caused this blood clot in her lungs..Help if you can...thanks
