Subclinical Primary Aldosteronism and Major Adverse Cardiovascular Events: A Longitudinal Population-Based Cohort Study
- Prospective population-based cohort study
- randomly sampled
- administrative database linkage
Authors' conclusion
Independent of blood pressure, the subclinical PA biochemical phenotype is associated with an increased risk of MACE.
Study context
- Population
- Canadian adults 40 to 69 years of age from the CARTaGENE cohort (Québec, Canada), aldosterone and renin measured at enrollment (2009–2010)
- Participants
- 2,017 adults
- Exposure
- Aldosterone, renin and aldosterone-to-renin ratio vs MACE risk
- Outcome
- MACE:
- MI
- Stroke
- Hospitalization for HF
- CV death
- Follow-up
- Median 10.8 years
