The Claim
In patients with established cardiovascular disease, an estimated 24-hour urinary sodium excretion between 4.59 and 4.97 grams per day is associated with the lowest risk of major adverse cardiovascular events and all-cause mortality, whereas both lower and higher levels of sodium excretion are associated with increased risk, indicating a J-shaped relationship.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
For people who already have heart disease, eating just the right amount of salt — not too little and not too much — seems to be linked to the lowest chance of heart problems or dying from any cause. Too little or too much salt might actually be riskier.

In patients with established cardiovascular disease, estimated 24-hour urinary sodium excretion between 4.59 and 4.97 grams per day is associated with the lowest risk of major adverse cardiovascular events and all-cause mortality, while both lower and higher sodium excretion levels are associated with increased risk, suggesting a J-shaped relationship.
What the research says
1 studyThis study found that heart disease patients who excrete about 4.6 to 5.0 grams of sodium per day have the lowest risk of heart problems or dying, and those who eat much less or much more sodium have higher risks — just like the claim says.
