I have an identical twin sister, in excellent. keeps her weight down, exercises 30 minutes a day, eats a healthy diet, no red meats, maybe once a month, doesn't smoke, her bloodwork is excellent, especially her cholesterol. LDL 99, HDL 82, Trigyserides 45, and everything esle is great. Se has been going to her doctor for the past 10 years, until he retired. She started to see another doctor, 2 weeks ago. He found a slight murmur, she had an EKG, which was good, doppler, good, and and echocardiogram which the finings were a mild leak in the mitral valve. She is a basket case right now and so am I, because we are very close. Her doctor said not to worry, but of course she is upset. why did her previous doctor never found it, and her new doctor found it. He said not to worry, and she'll take an echo every year, but she is freaking out, because she feels so good. No shortness of breath, never fatigue, no palpitations and she is very active. By the way we both get the white coat syndrome.
