That study is focused on how much to restrict sodium intake in patients who have already experienced heart failure to avoid further clinical events (more heart attacks). The evidence for excess sodium intake causing cardiovascular problems (by way of either high blood pressure or tissue damage from sodium spikes) remains pretty robust. See for example https://pmc.ncbi.nlm.nih.gov/articles/PMC8470268/ https://pmc.ncbi.nlm.nih.gov/articles/PMC8470268/. I think the closest thing to what you're saying that has been found is that very low sodium levels in the diet also lead to problems (the body is starved of electrolytes).
