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.
