I was recently taken to the hospital because my lungs were filling with water and phlegm. At that time, they said it was Pneumonia. But I had to go back a second time, and this time, they said my lungs were filling with water and phlegm, and my heart was enlarged. Now, they said the water in my lungs has nothing to do with pneumonia but is caused by my heart being enlarged. According to my latest X-Ray results, I have Cardiomegaly, left ventricular form. According to my 2D Echo, I have Mitral Sclerosis with moderate mitral regurgitation. Are those caused by pneumonia? What's the best way to go about this? My doctor can't seem to make up his mind on what's causing them.
