Background

Psoriasis is associated with risk of cardiovascular (CV) disease (CVD) and a major adverse CV event (MACE). Whether psoriasis duration affects risk of vascular inflammation and MACEs has not been well characterized.

Objectives

We utilized two resources to understand the effect of psoriasis duration on vascular disease and CV events: (1) a human imaging study and (2) a population-based study of CVD events.

Methods

First, patients with psoriasis (N = 190) underwent fludeoxyglucose F 18 positron emission tomography/computed tomography (duration effect reported as a β-coefficient). Second, MACE risk was examined by using nationwide registries (adjusted hazard ratios in patients with psoriasis (n = 87,161) versus the general population (n = 4,234,793).

Results

In the human imaging study, patients were young, of low CV risk by traditional risk scores, and had a high prevalence of cardiometabolic diseases. Vascular inflammation by fludeoxyglucose F 18 positron emission tomography/computed tomography was significantly associated with disease duration (β = 0.171, P = .002). In the population-based study, psoriasis duration had strong relationship with MACE risk (1.0% per additional year of psoriasis duration [hazard ratio, 1.010; 95% confidence interval, 1.007-1.013]).

Limitations

These studies utilized observational data.

Conclusion

We found detrimental effects of psoriasis duration on vascular inflammation and MACE, suggesting that cumulative duration of exposure to low-grade chronic inflammation may accelerate vascular disease development and MACEs. Providers should consider inquiring about duration of disease to counsel for heightened CVD risk in psoriasis.

NIH cohort

The NIH cohort comprised 190 patients with mild-to-moderate psoriasis (Supplemental Table I; available at http://www.jaad.org), who were primarily middle-aged men (57% men), overweight, with mild insulin resistance (median insulin resistance of 2.77), but at low CV risk by Framingham risk score. Vascular inflammation assessed by TBR (mean ± SD = 1.70 ± 0.26) demonstrated increased vascular inflammation.10 Strong associations with vascular inflammation were seen for male sex, smoking, Framingham

Discussion

We utilized a human imaging study and a population-based study to investigate whether the duration of psoriasis increases the risk for CVD and MACEs, and we have presented novel and convincing evidence to suggest a detrimental effect of psoriasis duration on CVD beyond traditional CV risk factors, even in patients with low CV risk scores. Notably, every 1 SD increase in duration of psoriasis increases the TBR by 2.5%, which roughly translates into an absolute increase of 10% in future adverse
