Plasma Proteomics of Exercise Blood Pressure and Incident Hypertension

JAMA CardiolPublished

  • Proteomic association study with external cohort validation and mendelian randomization
  • multicohort
  • cis-protein quantitative loci mendelian randomization

Authors' conclusion

Plasma proteomic profiling of EBP identified a novel protein, TGFBR3, which may protect against elevated BP and long-term CVD outcomes.

Study context

Population
Healthy participants free of cardiovascular disease (CVD) (HERITAGE Family Study) who underwent 2 cardiopulmonary exercise tests; incident hypertension tested in Framingham Heart Study (FHS), Jackson Heart Study (JHS) and Multi-Ethnic Study of Atherosclerosis (MESA)from 763 assessed
Participants
681 participants
Outcome
Protein markers associated with exercise BP (EBP) and their association with incident hypertension
