Steroids help joint pain flares, but injections in clinic would be the more likely use, especially for someone with other issues. You avoid longterm oral steroids if possible.
Gold salts are a little old school but quite effective in about 1/3 to 1/2 of people with arthritis, particularly rheumatoid arthritis. They can be hard on the kidneys or bone marrow (rarely), but there are not cardiac-specific side effects. At least, not heart-damaging--it can slow the heart rate or cause flushing, but that's uncommon, and it isn't damaging to the heart itself. Also, the oral version has fewer side effects than ingested.
There are other oral meds like penicillamine, but those are for even more severe forms of arthritis. If you want something that points to joints, has no cardiac counterindications, and is taken by mouth, I think gold is a reasonable option. This would be most likely used in someone with significant pain who was in the relatively early stages of arthritis.
