Nat MedPublished

  • Randomised controlled trial
  • open-label
  • pragmatic
  • 6 hospitals in Nigeria

Enrolment August 2022 to September 2023; follow-up through May 2024

Authors' conclusion

In pregnant and postpartum women, AI-guided screening using a digital stethoscope improved the diagnosis of pregnancy-related cardiomyopathy.
