6. Retrospective TriNetX Network cohort study of adult PsA (N 123,031) pts, propensity- matched to non-PsA controls. PsA had signif higher CV morbidity: MACE (HR 1.74); mortality (HR 1.95); CHF (HR 1.96), MI (HR 1.71), & CVA (HR 1.49). bDMARDs reduced MACE (HR 0.95) & mortality (HR 0.92) vs csDMARDs   https://t.co/bHrq9KpwBM
