No the stents, if deployed correctly, cannot dislodge. However, I am more worried about the extreme adrenergic surge that occurs whith these rollercoaster rides: this causes tachycardia, elevations of blood pressure and sometimes decrease in coronary luminal size. In most people this is well tolerated, but your father received 2 stents which probably means that he had other plaque which was not severe and not treated. This plaque can include some less stable lesions, which may rupture when subjected to the increased flow of a roller coaster ride.
If he was my patient, then I would ask him if he has any symptoms of coronary ischemia, such as chest pain or shortness of breath. If not, and he is active in an aerobic exercise program, then I would say that the rollercoaster ride is safe. If he has any symptoms, the I would advocate a stress test prior to this event.
I had gone through angioplasy in India on 31/11/2007, at Max Hospitl Delhi three stent to my artery, My self is working in DUBAI again I am getting chest pain as before,hardly two and half month pass.
