Hi. I feel so foolish even complaining and I am so grateful for your forum. I will be 53 next month. I recently went to the cardiologist for a pre-op clearance and learned I have three leaky valves, aortic is mild to moderate, mild mitral valve and mild tricuspid. Ejection fraction is 65%. I know this is good, but I have been Sob for months, coupled with extreme lethargy. I've been vigilant about checking thyroid function, and after exhaustive tests, have been told I have the beginning of thyroid disease. I have two aunts with thyroid cancer, both sides of family and cousins on both sides with hypothyroidism. I was frustrated that my tests were always borderline, but I still didn't feel right. I was shocked when the doc told me about my heart. Since my early 30s, I've had what I now think we're heart palpitations, flushing, warmth and dizzy spells. Often, I get visual disturbances, grey-outs, with peripheral vision. This has happened since my 20s. I used to think it was hypoglycemia, but for the last 15 years it occurs with a proper diet. Have such a mish-mash of symptoms that I feel like I get bounced around from doc to doc. Last week, I had an extreme dizzy spell for no discernible reason. I feel like I have to wait until I have an MI before someone pays attention. I'm not a hypochondriac, nor am I histrionic, but this getting bounced around is getting frustrating. I don't have chest pain, but rather chest tightening. Btw, I have extensive heart disease, both sides of family and my paternal grandmother died at 53, mi followed by stroke. Thoughts?
