title: Ask the doctor.  I had a stent put in several years ago, at age 59.  Thanks to a better diet, more exercise, a statin, and niacin, my LDL, HDL, and triglycerides are excellent.  My latest nuclear stress test showed some ischemia, even though I am not having any symptoms, and the follow up angiogram showed several new blockages requiring two additional stents.  I think my cardiologist should order tests like apolipoprotein A, LDL particle size and number, etc., to dig more deeply into why my coronary arteries keep getting clogged despite my best efforts.  Is that a good idea or a waste of time and money?
