My allergist recently had to have two stents implanted.   He is not overweight and very active.  He said there is some research that indicates "spinning" or any other activity that elevates heart activity may cause this.  Is that true? He said his doctor advised hin not to do any exercises that cause rapid heartbeats.
Hello welcome to Chat Doctor. Activities that increase the heart rate increase the blood and oxygen requirement of the heart. So if the heart arteries already have blockages, then the extra demand is not met, and you may experience chest pain or discomfort. Do if you have established critical blockages in your heart, then activities increasing the heart ray should be avoided. These activities themselves do not lead to blockages in the heart. It may aggravate the symptoms due to increased demand during exertion. Also, on a stenting is done, the blockages are tackled and hence demand is met, and the person can go back to his normal activities. I hope I have answered your query satisfactorily. Wishing you good healthRegards
