Yes, but it's not a short-term boost like with Covid.
I mean it in that Covid will look worse and heart disease better on a short scale, but in the grand scheme of things Covid will die down and heart disease come back, since you don't have immunity or vaccines against heart disease. That means that comparing (for the same year) covid vs heart disease is somewhat useless (since covid is an exceptional and short-lived event).
Fixing both problems will probably move deaths to another category (since that is the purpose of having categories), but the argument was that addressing covid has less benefits than addressing heart disease (mostly because covid addresses itself over time, whatever lockdown/mask wearing we do, but heart diseases do not).
