Sorry to hear that TV.
If you can go, I would. He may say he is fine but there is always the risk of another one (don't want to sound pessimistic).
My Dad had a small stroke after heart surgery about this time of year in 1994. As a teacher I was busy with reports, formals, assemblies etc and work was not forthcoming on leave outside school holidays so did not manage to get down to Melbourne until school finished. He had been going well but the night before I went down he had a massive bleed and was in Intensive Care. The first day I saw him he could speak a little and recognised me, the second day he was worse. He hovered like that for another week or so and passed away on Boxing Day. I always regret that I didn't push work and go down before I did.
When MrL_t_L had a small stroke when he was based in Adelaide, I was much more assertive and simply rang work and told them I was on the way to Adelaide and I would send lesson plans when I could!
