72yr old Female[my mom], had stent 1 1/2yrs ago, 60% occluded other side, is on plavix, lipitor [LDL-130, HDL-55], atenolol, is in cardiac rehab, lost 18lbs, but remains obese. She is asymptomatic. She wants to go off plavix to have torn meniscus repair and gyn sugery for stress incontinence. Docs been saying "no" for last six months. My dad pressed them to due repeat stress test to see if she is" OK" , because he wants her to get knee done.{She's in pain}. Stress test was good. Wouldn't a CRP/hs-CRP give us a look at where she really stands? If in the 3mg/l-- 10mg/l range or higher, she is at greater risk for the stent to thrombose or the plague to rupture---putting her at risk for acute cardiovascular events? If high, get more aggressive in getting her LDL and CRP down and give her meds to help pain in knee.[ She is walking and going to cardiac rehab, so she is not immbolized.] Thanks for your help, R.N., who wishes she lived in same state as parents :}
