Hi Dear !! Thanks for your query to HCM. I reviewed facts of your query in context to your health issues. My Opinion- In My opinion, in the given situation you seen to be cautious to avoid risks from roller coaster rides,as it could increase chance of complications of rupture of CIA(Common iliac Aneurysm)/ and thromboembolic events from CIA. Any act which would increase your blood pressure is risk increasing factor and needs to be avoided as far as possible. Do s Suggested- You can go on vacation but avoid roller coster or such events. Consults with Physician-who would check for high bp and would start needful medicines-like antihypertensives etc to reduce on complications of CIA,depending on status of CIA in your case. Any act which would increase your blood pressure is risk increasing factor and needs to be avoided as far as possible. About the treatment options-stent or coils or surgery would be decided as per your case study,after knowing its details. So better leave it to attending Consultant,than confusing and worrying on the issue. Next appointment- After 2 weeks to review treatment for existing stomach problem .
