Abstract Background Psoriatic disease (PsD) is closely associated with cardiovascular (CV) disease. The Life’s Essential 8 (LE8) score is a new metric to assess CV health (CVH), where a higher score indicates better CVH. However, the longitudinal association between LE8 score and the risk of PsD remains uncertain. Objectives To investigate, in a cohort study, the association between LE8 score, genetic susceptibility and the risk of PsD. Methods This cohort study included 261 642 participants in the UK Biobank without PsD at baseline. LE8 comprises eight indicators: diet, physical activity, nicotine exposure, sleep health, body mass index, blood lipids, blood glucose and blood pressure. Cox proportional hazard models were used to examine the association between participants’ LE8 scores, genetic risk of PsD and the risk of PsD. Hazard ratios (HRs) and 95% confidence intervals (CIs) were calculated. Results During an average follow-up of 12.3 years, 1501 participants developed PsD. Compared with participants with low LE8 scores, the HRs of developing PsD for those with moderate and high LE8 scores were 0.51 (95% CI 0.43–0.59) and 0.34 (95% CI 0.27–0.42) after adjustments, respectively. Dose–response analysis revealed a linear negative association between continuous LE8 score and the risk of developing PsD (P 0.001), with no evidence of nonlinear association detected. Genetic susceptibility to PsD did not modify this association (Pinteraction = 0.63). Subgroup analyses revealed that women had a more pronounced beneficial association between LE8 scores and PsD risk (Pinteraction = 0.02). Conclusions Our study suggests that a higher LE8 score, regardless of genetic risk, is associated with a lower risk of PsD, particularly in women. Consequently, maintaining good CVH status is recommended to prevent PsD and assess associated risks.
