My father is 65 and has high blood pressure. Last October he had a severe blockage and had a stent put in. He is on lots of blood pressure medicine and over the last 4 weeks his blood pressure has been really high. We are very concerned that the stent has become glogged again which is some thing that can occur frequently from what I'm starting to learn. I'm am extremely worried about my father and we are not confident in his current cardio doctor and are looking for another doc. He is schedule to go in March 14th for a nuclear test which will check the status of his stent and for any additional blockages in his heart. This test is still 2 weeks away. I would like to research stents in general for Cardio, can any one tell me of some great sites for information about stents?
