Unfortunately the link you chose is crappy. It is a qualitative study debunking the claim "some researchers have propagated a myth that lower sodium might increase the risk of CVD, This article analyzes the eight articles as a case study" (paraphrased). Too little salt is not the issue, why would that paper be useful?
The clear advice is to lower salt intake, but from what I can tell statistical data doesn't show that doing that actually lengthens life. Admittedly, cause and effect is difficult science, even in well funded large population studies. Correlations and case studies are much easier science.
Personally I don't have a horse in the race because I have a relatively low salt intake: I don't like the taste of over-salting and I also try to avoid high-salt foods because they are often crappy industrial foods (correlation).
I did google for papers before making my original comment, but I struggled to find any papers I liked. I remember that one paper in particular was a meta-study: I really really hate those.
Edit: I asked Gemini, and it referenced this paper: https://www.jacc.org/doi/10.1016/j.jacc.2016.07.745 which seems fairly balanced: the first sentence is a soft "The relationship between lower sodium intake and total mortality remains controversial". I did a couple more follow-on prompts and Gemini referenced results from Britain lowering salt in processed foods "A 36\% decrease in mortality rates from stroke and ischemic heart disease (heart attacks) during the period of the salt reduction program.". https://g.co/gemini/share/42637d5a2dfb I feel embarrassed rereading my prompts since they show my ignorance and other problems, but the eventual AI results are interesting. Asking the right questions is hard...
