If somebody is acquitted of GBH on the grounds of self-defence, but the victim later dies, does the accused have to be retried?

I mean, the death, within the year, is related to the injury sustained in the GBH incident. Would a new charge of murder/manslaughter be brought forward, or would their successful defence for the original charge preclude anything like that (case closed)? (This isn't a situation I'm personally in, just a hypothetical I'm wondering about. Search engines aren't bringing up any useful answers so I thought I'd pick Reddit's brains!)
