  • Secondary analysis of the ESPRIT randomised trial
  • multicentre
  • 116 sites in China
  • subgroup at 17 sites

Authors' conclusion

Among hypertensive patients with high cardiovascular risk, lowering systolic blood pressure with a target of <120 mm Hg compared with <140 mm Hg has a favorable impact on retinal microvasculature

Study context

Population
Adults aged ≥50 years with high CV risk, China
Participants
555 vs 526
Comparison
Intensive vs standard SBP lowering
  • Intensiven = 555
  • Standardn = 526reference
Primary endpoint
Arteriole-venule ratio (retinal arteriolar caliber)
Follow-up
3-year follow-up
