It's actually a bump around 1981 or so, and then a sharp decline, followed by a resurgence in 1985.
It seems to occur in the "Heart and Circulatory Disease" category.
I'm not sure what this translates to specifically, but if they are classifying AIDS deaths as a "circulatory disease" and not pneumonia, it could be that.
There was also a severe famine in Africa in the 80's. Do you die of a heart attack if you are starving? Not sure.
It could also just be the pattern of heart disease/healthy living/research was playing out... notice that afterwards, the category accounts for decreasing amounts of death.
