Insights
Severe psoriasis significantly increases mortality risk after percutaneous coronary revascularization (PCI). Patients with severe psoriasis face higher risks of death and major adverse cardiovascular events post-PCI compared to those without psoriasis.
Area of Science:
- Cardiology
- Dermatology
- Public Health
Background:
- Psoriasis is linked to higher coronary artery disease risk.
- The effect of psoriasis on outcomes after percutaneous coronary revascularization (PCI) remains unclear.
Purpose of the Study:
- To investigate the prognosis of patients with psoriasis undergoing first-time PCI.
- To assess the association between psoriasis severity and adverse cardiovascular outcomes post-PCI.
Main Methods:
- A nationwide cohort study of all Danish patients undergoing first-time PCI (2002-2009).
- Cox regression models were used to analyze risks of all-cause mortality and a composite endpoint (death, myocardial infarction, stroke).
- Analyses controlled for demographic, socioeconomic, and clinical factors.
Main Results:
- Severe psoriasis was associated with a significantly increased risk of all-cause mortality (HR 1.67) and the composite endpoint.
- Mild psoriasis did not show a statistically significant increased risk for either endpoint.
- Patients with severe psoriasis were less likely to receive guideline-recommended secondary prevention pharmacotherapy.
Conclusions:
- Severe psoriasis is an independent risk factor for poor prognosis after PCI.
- This highlights a novel association between severe psoriasis and adverse cardiovascular outcomes.
- Further research is warranted to understand and mitigate these risks.
Background:
Psoriasis is an inflammatory disease associated with increased risk of coronary artery disease. However, the potential impact of psoriasis on the prognosis following percutaneous coronary revascularization (PCI) is unknown.
Methods:
The study comprised the entire Danish population undergoing first-time PCI in the period 2002-09. Cox regression models, controlling for age, gender, socioeconomic status, pharmacological treatment, and comorbidity were used to assess the risk of 1) all-cause mortality and 2) a composite endpoint of death, myocardial infarction, and stroke.
Results:
A total of 53,141 patients with first-time PCI in the study period were identified. Of these, 1074 had mild psoriasis and 315 had severe psoriasis. Patients with severe psoriasis, but not those with mild disease had increased risk of both endpoints compared to patients without psoriasis. The incidence rates for all-cause mortality were 30.5 (CI 29.7-31.3), 29.9 (CI 24.7-36.1), and 47.2 (CI 35.0-63.6) per 1000 patient years for patients without psoriasis, with mild psoriasis, and with severe psoriasis, respectively. Hazard ratios were 1.10 (CI 0.91-1.33) and 1.67 (CI 1.24-2.26) for mild and severe psoriasis, respectively. Patients with severe psoriasis were less likely to receive secondary prevention pharmacotherapy with betablockers, statins and platelet inhibitors.
Conclusion:
This first study of the prognosis following PCI in patients with psoriasis demonstrated an increased risk of all-cause mortality and of a composite of death, myocardial infarction and stroke, respectively, in patients with severe psoriasis compared to patients without psoriasis. Further studies of this novel association are needed.
