非酒精性脂肪肝引起心血管疾病機轉探討

摘要


非酒精性脂肪肝(nonalcoholic fatty liver disease, NAFLD)在全球的盛行率逐年升高至每4人就有一位患有非酒精性脂肪肝。非酒精性脂肪肝病人同時有較高風險死於心臟血管疾病之事實漸被重視。非酒精性脂肪肝與心臟血管疾病共同危險因子包含血脂異常、慢性發炎、以及血栓形成(thrombosis),研究指出與非酒精性脂肪肝致病機轉有關的基因:PNPLA3、TM6SF2、GCKR,此3者基因突變可引起血脂異常進而導致非酒精性脂肪肝,然而PNPLA3、TM6SF2基因卻在一些研究中被發現可能是心血管疾病之保護因子,GCKR基因則是被發現與心血管疾病有正相關。本文概述非酒精性脂肪肝與心血管疾病之關聯機轉和假說。
