Must be vessel-inflammation or something similar in latin. Angiogenesis -> blood vessel formation (angio being blood vessel), -ina is a suffix for inflammation, therefore angina -> blood vessel inflammation
This is speculative from my working knowledge of some biological terms, I haven't looked up the etymology (yet)
edit after google:
-
there are many medical anginas https://en.wikipedia.org/wiki/Angina_(disambiguation)
-
I was right for the wrong reasons. The etymology is greek: ankhonē "a strangling". Originally it referred to the aforementioned throat infection in english, then evolved into chest pain. https://www.etymonline.com/word/angina
