Hi everyone: Would appreciate your thoughts on what are left ventricular dysfunction and mitral regurgitation. Both conditions diagnosed at once on an echocardiogram. I was not aware that I had both (since 2001) until I went through my medical record from a local hospital. I immediately sent a copy to my GP and was referred once more to a cardiologist. Further tests will be made to ensure that this has not developed further. Is left ventricular dysfunction and mild regurgitation acually the same as heart failure? Or can it lead to heart failure if not monitored? Can these lead to valve damage? I should have been given antibiotics when having tooth abcesses over a period of two months earlier this year! Am just very worried that this could have led to further deterioration...... Also, I recently became breathless, chest pain and nail bed of the left thumb turned blue. I went to A & E and the oxygen saturation went down to 93% walking a few steps. The duty doctor mentioned that I should see a respiratory specialist???? According to him, it could be blood clots from my varicose veins in both legs attacked to the lungs and causing some sort problems with the pulmonary artery! I saw a cardiologist last week. An ECG came back normal, a chest x-ray I do not know the result yet. A cardiac MRI is in the pipeline and the cardiologist suggested a stress treadmill test. I am not sure that I will be able to do this though. I do become breathless on minimal exertion. The cardiologist mentioned that the episode when my nail bed turned blue in the left thumb, this could be angina! Many thanks for explaining what the two main symptoms are? It is quite important to be informed and therefore, self monitor and find out how best to maintain a fair baseline ... Regards. Kooky.
