six months ago I had two stents placed in my lad coronary due to severe chest pain (occasional) had no heart attack..since then I am experiencing occasional chest and throat discomfort ..I am taking isosorbide, amlodopine plavix baby asprin and lipitor..I am going crazy with this issue...my doc. says I have coronary spasms and they should have gone away by now...why have they not? I am a 70 year old woman in otherwise good health..non smoker, not heavy and play golf or walk three miles a day for the past 30 years..not high blood p. or high colestoral...after ready the harvard news letter I asked my doc. to test my Lipoprotein level it should be below 20 mine is 247 has anyone else heard of this...my recent understand is that..this should have been looked a long time ago..as it is very dangerous, perhaps more so than hdl or ldl levels????help>>>p.s. the doc's have looked into my coronaries and additional 3 times (post stent) and find all things in good order
