For many years psoriasis was considered an inflammatory condition restricted to the skin. However, nowadays it is considered an immune-mediated, systemic inflammatory condition associated with numerous medical comorbidities, particularly cardiometabolic diseases, and overall cardiovascular mortality. Several studies have suggested that psoriasis may be an independent risk factor for atherosclerosis, indicating that psoriasis itself poses an intrinsic risk for cardiovascular disease, probably due to the disease's inflammatory burden. However, other causes beyond systemic inflammation and traditional cardiovascular risk factors may be implicated in cardiovascular disease in psoriasis. Recently, epicardial adipose tissue, an emerging cardiovascular risk factor, has been shown to be increased in psoriasis patients and to be associated with subclinical atherosclerosis, providing another possible link between psoriasis and atherosclerosis. The reason for the increase in epicardial adipose tissue in patients with psoriasis is unknown, but it is probably multifactorial, with genetic, immune-mediated and behavioral factors having a role. Thus, along with the increased prevalence of cardiometabolic risk factors and systemic inflammation in psoriasis, epicardial adipose tissue is probably another important contributor to the higher cardiovascular risk observed in psoriasis.
多年来,银屑病一直被认为是一种局限于皮肤的炎症性疾病。然而,如今它被视为一种免疫介导的全身性炎症性疾病,与多种内科合并症相关,尤其是心脏代谢疾病和总体心血管死亡率。多项研究表明,银屑病可能是动脉粥样硬化的独立危险因素,这表明银屑病本身就构成了心血管疾病的内在风险,可能是由于该疾病的炎症负担所致。然而,除了全身性炎症和传统心血管危险因素之外,其他原因也可能与银屑病患者的心血管疾病有关。最近,心外膜脂肪组织作为一种新出现的心血管危险因素,已被证明在银屑病患者中增多,并与亚临床动脉粥样硬化相关,这为银屑病和动脉粥样硬化之间提供了另一个可能的联系。银屑病患者心外膜脂肪组织增多的原因尚不清楚,但可能是多因素的,遗传、免疫介导和行为因素都起到了一定作用。因此,除了银屑病中心脏代谢危险因素和全身性炎症的患病率增加之外,心外膜脂肪组织可能是银屑病中观察到的较高心血管风险的另一个重要促成因素。
