Excess cardiovascular morbidity in psoriatic arthritis and cardioprotective effects of biologic dmards: a propensity-matched analysis.

TL;DR

PsA confers substantial excess cardiovascular risk comparable to other inflammatory arthropathies, and biologic DMARDs modestly reduce cardiovascular events, supporting their role in comprehensive PsA management.

Key Findings

Patients with psoriatic arthritis had significantly higher rates of major adverse cardiovascular events (MACE) compared to propensity-matched controls.

  • HR for MACE was 1.74 in PsA patients versus controls
  • Incidence rates were 62.9 vs. 36.4 per 1,000 person-years for MACE
  • Study used 1:1 propensity-score matching of 123,031 PsA patients to 123,031 controls without PsA
  • Cox proportional hazards models were used to estimate hazard ratios
  • Data were drawn from the TriNetX Global Health Research Network covering 2002–2025

All-cause mortality was substantially higher in PsA patients than in matched controls.

  • HR for all-cause mortality was 1.95
  • Incidence rates were 60.2 vs. 31.0 per 1,000 person-years
  • This nearly two-fold excess mortality was observed after propensity-score matching on demographics, comorbidities, and medications

PsA patients experienced significantly higher rates of heart failure, myocardial infarction, and stroke compared to controls.

  • HR for heart failure was 1.96
  • HR for myocardial infarction was 1.71
  • HR for stroke was 1.49
  • All comparisons were made in propensity-matched cohorts of 123,031 pairs

The excess cardiovascular risk observed in PsA was robust to the potential influence of unmeasured confounding.

  • E-values ranged from 2.5 to 3.9 across the various cardiovascular outcomes
  • E-values indicate the minimum strength of association an unmeasured confounder would need to have with both treatment and outcome to explain away the observed results
  • Higher E-values indicate greater robustness to unmeasured confounding

Biologic DMARD (bDMARD) treatment was associated with a modest reduction in MACE and all-cause mortality compared to conventional synthetic DMARD treatment within the PsA cohort.

  • HR for MACE with bDMARDs vs. conventional synthetic DMARDs was 0.95
  • HR for all-cause mortality with bDMARDs vs. conventional synthetic DMARDs was 0.92
  • Comparison was made in 1:1 propensity-score matched groups of 44,870 bDMARD-treated versus 44,870 conventional synthetic DMARD-treated PsA patients
  • Matching was performed on demographics, comorbidities, and medications within the PsA cohort
