What Causes Sudden Shortness Of Breath That Has Lasted For 4 Years?
The shortness of breath came on one morning 4 yrs, ago. I have seen a cardiologist and had a stress test. He seems to think I am fine and shortness of breath caused by something else. I do have a mitral valve prolapse with regurgitation and high blood pressure, currently controlled with Toprol and Avapor. Thank you.
