Without going into too much detail, here is my situation. 66-yo male, treated for hypertension for 25 years (well controlled). Weight is good (6'0; 180), as are most of the standard test numbers (cholesterol (LDL is 88 HDL is 39 (!), triglycerides 77, etc). Several years ago after experimenting with a variety of hypertension drugs my pcp suggested I visit a cardiologist. He put me through the ringer - stress, echo, cardiac cath.
