Eur J Heart FailPublished

  • Population-based retrospective cohort study
  • cause-specific hazards regression
  • multiple covariate adjustment
  • stratified by age

Authors' conclusion

Patients with newly-diagnosed heart failure residing in the most deprived neighbourhoods had worse outcomes and reduced access to care than those less deprived.

Study context

Population
Incident HF patients in a universal healthcare system, 2007–2019
Participants
395,763 patients
Exposure
Most vs least deprived neighbourhoods
Outcome
All-cause mortality, cause-specific hospitalization and processes of care
Follow-up
1 year (mortality); 90 days (processes of care)

Main finding

As reported in the abstract

All-cause death and CV hospitalization, by age stratum · 1 year
Most deprived vs Least deprivedHazard ratio (95% CI)
age ≤65 years; all-cause death
1.19(1.10–1.29)
age ≤65 years; CV hospitalization
1.29(1.19–1.39)
age ≥66 years; death
1.11(1.08–1.14)
age ≥66 years; CV hospitalization
1.13(1.09–1.18)

Observational data: associations, not effects.

Further findings

Processes of care: cardiology visits and advanced cardiac imaging · 90 days

Lower hazard in more deprived individuals, both age groups
all p < 0.001

ICD/CRT-pacemaker implantation (age ≤65 years) · 90 days

Most deprived less likely to undergo implantation vs least deprived
P = 0.023
