Hello and thank you for using Heathcare magic. After reading your question, I must say that your concern is very just. My understandig is that you have suffered a heart attack (myocardial infarction) and have got a PCI (percutaneous coronary intervention) done with a stent placed in the coronary vessels that caused the infarction. In this stage you are considered cured. Amusement parks and roller-coasters during their rides produce joy and excitement by raising adrenaline and othes stress hormone levels. This means tht the heart has to respond to these stressed condition with faster heartbeats which means more work for the heart and also there is the possibility of stress induced coronary artery spasms which may lead to chest pain and myocardial infarction. My opinion is that you should undergo one of the functional stress test exercise ecg, stress echocardiography or nuclear stress test. After the test you will know how your heart responds on a sressed conditions and if the test resoults are good than I would say that you can enjoy amusement parks in moderation. I hope you got the answer you were seeking. If you are satisfied please rate my answer. If you have further questions feel free to contact me Best regards, Dr Astrit Ceka
