Sodium, blood pressure and heart disease
Blood pressure links sodium to cardiovascular disease. A rural Chinese salt-substitution trial reduced cardiovascular events, but changed potassium as well as sodium.
Educational only. Associations do not establish individual risk or diagnosis. Read the original sources and limitations.
Illustrative pathway
High-sodium diet → Raised blood pressure → Heart disease → Kidney disease
Relationship
Probable link: Consistent evidence with plausible mechanism; some gaps remain.
Evidence and uncertainty
Systematic reviews & meta-analyses; moderate uncertainty.
Summary
Blood pressure links sodium to cardiovascular disease. A rural Chinese salt-substitution trial reduced cardiovascular events, but changed potassium as well as sodium.
Limitations
Salt-substitute effects cannot isolate sodium alone or establish every downstream complication drawn here. Potassium-containing substitutes need individual safety assessment.
Data status
Synthetic illustration only. Map widths are not patient counts, prevalence, study effect sizes or personal risks. A paper does not validate every arrow.
