In Singapore, we also do advice our cardiac cath patients to complete rest in bed for 6 hrs,not to bend,strain or lift heavy objects during this time & not to sit upright.Now some of the senior cardiologists or the more experience ones are doing cardiac cath thru the artery or a vein of the arm so the patients does not need to be complete rest in bed and can ambulate to the toilet.But here majority cases,we still do it at the groin area.So we still have to advice patients like above.
