Severe psoriasis linked to a higher risk for heart disease, study confirms


 

FROM THE JOURNAL OF INVESTIGATIVE DERMATOLOGY

TOPLINE:

In a large cross-sectional study, nearly one-third of patients with severe psoriasis met criteria for coronary microvascular dysfunction (CMD).

METHODOLOGY:

  • Prior studies with small sample sizes have shown that CMD predicts poor cardiovascular outcomes in patients with severe psoriasis.
  • In a prospective multicenter study, researchers enrolled 448 patients with moderate to severe psoriasis with no documented clinical cardiovascular disease who underwent transthoracic Doppler echocardiography to evaluate coronary microcirculation.
  • The outcome variable of interest was CMD, defined as a coronary flow rate of 2.5 mL or less.
  • The researchers used multivariable linear regression to model the associations of the characteristics of patients with psoriasis with CMD.

TAKEAWAY:

  • Of the 448 patients, 141 (31.5%) showed CMD.
  • Multivariable regression revealed four variables independently associated with CMD: higher Psoriasis Area Severity Index (PASI) score (per unit, odds ratio, 1.058; P < .001), duration of psoriasis (per year; OR, 1.046; P < .001), the presence of psoriatic arthritis (OR, 1.938; P = .015), and hypertension (OR, 2.169; P = .010).
  • An increase of 1 point in the PASI score and 1 year of psoriasis duration were associated with a 5.8% and a 4.6% increased risk for CMD, respectively.

IN PRACTICE:

“We should diagnose and actively search for microvascular dysfunction in patients with psoriasis, as this population is at particularly high risk,” the researchers wrote.

SOURCE:

Stefano Piaserico, MD, PhD, of the University of Padova (Italy), led the research. The study was published in the Journal of Investigative Dermatology.

LIMITATIONS:

A small proportion of patients in the study were being treated for psoriasis, and other tools for assessing CMD were not used, such as PET-CT and cardiovascular MRI.

DISCLOSURES:

The authors reported having no relevant financial disclosures.
