I also had small sticking sensations in and around my chest after 2 stents in January 2012, but the fast heart rate and nervousness were because of meds like statins, and plavix. Now I am off statins and taking blood thinner Effient. The little poking sensations come and go only now and then. You need to discuss with doctor. Then I had a stress test that showed the good functionality of my 72 year old heart thanks to regular exercise and strict diet. It's an ongoing process. Sometimes I feel strange sensations in my chest area, may be trachea or esophagus, or costal-condroital. Can't get stressed about it. Dr. gave me xanax if I feel fast heart rate coming on.View Thread
