Objectives:
Psoriasis is a chronic inflammatory disease that is associated with a prothrombotic state and cardiovascular disease, including atrial fibrillation and thromboembolism. We therefore evaluated the impact of psoriasis in patients with atrial fibrillation and the performance of the CHA2DS2VASc score in these patients.

Design, setting, and participants:
The study comprised all Danish patients hospitalized with non-valvular atrial fibrillation in the period 1997-2011 (n=99,357). Follow-up started 7 days from discharge and excluded subjects treated with anticoagulation. Poisson regression adjusted for CHA2DS2VASc score were used to estimate the incidence rate ratios and 95% confidence intervals.

Main outcome measure:
Hospitalization or death from thromboembolism.

Results:
Mean follow-up was 3.5, 3.1, and 2.8 years for patients with no psoriasis, mild psoriasis, and severe psoriasis, respectively. Patients with psoriasis were younger compared to patients without psoriasis, but CHA2DS2VASc score did not differ between the 3 groups. Thromboembolism rates per 100 patient years (95% confidence intervals) were 4.8 (4.7-4.9), 4.8 (4.2-5.4), and 6.1 (5.0-7.5) for patients with no psoriasis, mild psoriasis, and severe psoriasis, respectively. Importantly, the observed thromboembolism rates in patients with severe psoriasis were markedly higher (2.6–3.4 fold) than predicted by the CHA2DS2VASc score. Relative to no psoriasis, incidence rate ratios were 0.99 (0.87-1.11) and 1.27 (1.02-1.57) for mild and severe psoriasis, respectively. Correspondingly, incidence rate ratios for fatal stroke were 0.97 (0.80-1.12) and 1.51 (1.12-2.05).

Conclusions:
In patients with non-valvular atrial fibrillation not treated with oral anticoagulation severe psoriasis was associated with increased risk of thromboembolism. In these patients CHA2DS2VASc underestimated the risk of thromboembolism.

I've discussed this on another forum.
Conclusion over there by a guy that really made a study of it, because of genetic history in his family, is that systemic medication that reduces the inflammation is in the case of psoriasis a very positive approach.
Related to this specific point much better than ointments and so.
