Abstract
Background: No previous study has investigated the incidence or risk of acute myocardial infarction
(AMI) developing after the diagnosis of psoriasis in Asian populations.
Objective: We sought to evaluate the association between psoriasis and subsequent AMI during a 5-year
follow-up period, using a nationwide Taiwanese population-based claims database, and taking clinical and
demographic characteristics into consideration.
Methods: Our study cohort consisted of all patients with a first recorded diagnosis of psoriasis (N = 4752)
between 1999 and 2001 and of patients without a diagnosis of psoriasis (N = 23,760) who were matched by
age and sex (1:5) to the patients with psoriasis. Each patient was tracked using hospitalization data from
2001 until the end of 2006. Stratified Cox proportional hazard regressions (stratified by age and sex) were
performed as a means of computing the 5-year AMI-free survivals after adjusting for possible confounding
factors.
Results: Of the total sample, 70 patients (0.2%) had AMIs during the 5-year follow-up period: 22 (0.5% of
the patients with psoriasis) from the study cohort and 48 (0.2%) from the comparison cohort. After adjusting
for other factors, the hazard of AMI during the 5-year follow-up period was 2.10 times greater (95%
confidence interval 1.27-3.43, P = .004) for patients with psoriasis than for comparison patients.
Limitations: We could not take into account some known risk factors for AMI, such as smoking and body
mass index.
Conclusions: Psoriasis may confer an independent risk of AMI in Asian populations.We suggest that patients
with psoriasis be made aware of the increased risk of AMI. ( J Am Acad Dermatol 2011;64:495-501.)
