Authors' conclusion

TCAD was not associated with reduced survival in patients alive and well enough to undergo post-HT angiography within the first 3 months; however, s-TCAD patients showed increased risk of cardiovascular death and MACE.

Study context

Population
Consecutive adults undergoing heart transplantation in 11 Spanish centres, 2008–2018, with coronary angiography within 3 months after heart transplantation (HT)cohort of 1,918
Participants
937 adults
Exposure
Donor-transmitted CAD vs no TCAD
  • Significant TCAD (s-TCAD)n = 65
  • Nonsignificant TCAD (ns-TCAD)n = 107
Outcome
Prevalence of TCAD and its prognostic relevance (clinical outcomes)
Follow-up
Median 6.3 years after c-angio

Main finding

As reported in the abstract

TCAD prevalence
Any TCAD: 172 patients
