Blood levels of renin are linked to organ damage and death
In 48,739 UK Biobank participants followed for a median of 15.3 years, lower renin was linked to higher blood pressure and higher renin to increased mortality.
Limit: Results from UK Biobank participants may not apply to other populations

In an observational study of 48,739 participants from the UK Biobank cohort, researchers evaluated blood concentrations of renin, an enzyme that helps regulate blood pressure. Over a median follow-up of 15.3 years, 6,714 all-cause and 1,470 cardiovascular deaths occurred.
In fully adjusted models of 30,648 participants, predicted systolic blood pressure differed by about 15 mmHg between the 5th and 95th renin percentiles. Lower renin concentrations were associated with higher blood pressure, higher pulse wave velocity, a measure of arterial stiffness, and greater left ventricular wall thickness in the heart. In contrast, higher renin concentrations were strongly associated with increased all-cause and cardiovascular mortality. Standard markers of organ damage did not account for most of the link between renin and death; only kidney function and heart rate showed measurable mediation.
Why it matters
Cardiovascular disease and high blood pressure are leading causes of illness and death as people age. Understanding how renin relates to mortality through pathways beyond blood pressure may help clarify how cardiovascular health deteriorates over time.
Caveats
Because the study design was observational, the findings show associations rather than cause and effect. In addition, the results come from a conference abstract of UK Biobank participants, which may limit how well they apply to other populations.
