在2017ESC年会上,浙江省人民医院钱琳艳教授带来了一项Rapid Fire Abstract口头报告,探讨了非高血压人群的血压水平与非酒精性脂肪肝NAFLD)的相关性。这项研究结果如何,对临床实践有哪些意义?我们就上述问题对钱教授进行了采访。



医脉通:请您介绍一下这项研究及其临床意义?


钱琳艳教授:众所周知,脂肪肝与高血压的关系是很密切的。现在很多人有脂肪肝而没有高血压病史。我们想分析这部分无高血压人群的脂肪肝发病风险,以便实现早期预防。


最后的统计结果显示,血压在正常范围的患者,其血压值与脂肪肝发生有一定的相关性。血压处于正常高值的患者发生脂肪肝的风险高于血压较低的患者。研究也发现,非高血压人群如果有脂肪肝,那他以后发生高血压的风险也会升高。这部分人群需要提前干预,改善代谢性疾病状态、改善脂肪肝的严重程度,延后或避免其发生高血压。


医脉通:当脂肪肝患者发生高血压后,其血压应该控制在什么水平?


钱琳艳教授:对于这个问题,我认为需要更长期的数据来解答。可能是5年或10年随访之后,我们才能知道干预或顺其自然的患者会怎样,这项研究对我们的临床工作还是有帮助的。


对于血压处于正常高值的脂肪肝患者,其血压再低一些会不会更好?这是个很复杂、很困难的问题。目前的降压指南对不同年龄、不同疾病状态的推荐有很多,但没有明确指出脂肪肝合并高血压患者必须怎样做。所以,对于这个问题,的确需要通过大样本数据才能得出结论。


研究摘要:Association of blood pressure level with nonalcoholic fatty liver disease in non-hypertensive population: normal is not the new normal


Background and aim: Some literatures have reported the relationship between NAFLD and hypertension, but there is no article describes the characteristic of NAFLD in non-hypertensive individuals. This study aimed to determine the strength of the association between NAFLD with normal BP in non-hypertensive individuals.

Method: A cross-sectional study was conducted among patients who came to the sixth Affiliated Hospital Medical University from October 2007 to December 2011.

Results: Of the 24200 enrolled subjects, 5305 filled the diagnostic criteria for NAFLD (21.9%; 4803 males and 502 females). Non-hypertension was identified in 17403 (71.9%; 8179 males and 9224 females). The PR% of NAFLD for the SBP in quartile 1, quartile 2, quartile 3, and quartile 4 was 10.83, 12.55, 20.38, and 19.97. SBP, DBP, sex, age, ALB, GPT, GOT, FPG, UA, TG, HDL-C and LDL-C are closely associated with the risk for NAFLD. SBP (OR: 1.092, 95% CI: 1.030–1.158; P<0.05) and DBP (OR: 1.157, 95% CI: 1.094–1.223; P<0.05) were found to be independent risk factors for NAFLD.

Conclusions: BP is significantly associated with NAFLD in non-hypertensive individuals; SBP and DBP are found to be independent risk factors for NAFLD.
