概括
心脏代谢指数 (CMI) 是一种新的工具,与非酒精性脂肪性肝病 (NAFLD) 和肝纤维化有正相关. 这项研究表明,CMI是这些肝脏疾病的简单而有效预测指标.
科学领域:
- 心脏病学 心脏病学
- 肝病学 肝病学是一种肝病学.
- 代谢综合征是代谢综合征的一种.
背景情况:
- 心脏代谢指数 (CMI) 是从肥胖和脂质参数中得出的,是糖尿病和心血管疾病的诊断工具.
- 它与非酒精性脂肪性肝病 (NAFLD) 和美国人口中的肝纤维化相关性尚未得到充分证实.
研究的目的:
- 调查CMI与NAFLD和肝纤维化患病率之间的关系.
- 评估CMI在检测NAFLD和肝纤维化方面的诊断性能.
主要方法:
- 对2996名美国成年人的横截面分析 (2017-2020年NHANES数据).
- 通过FibroScan®,使用受控衰减参数 (CAP ≥274 dB/m) 确定NAFLD.
- 通过肝硬度测量评估的肝纤维化 (LSM ≥ 8.2 kPa).
- 多因素后勤回归和ROC曲线分析用于评估CMI的关联和预测价值.
主要成果:
- 在对混因素进行调整后,CMI显示与NAFLD (aOR=1.44) 和肝纤维化 (aOR=1.84) 有显著的积极关联.
- 预测NAFLD的CMI曲线下的面积 (AUC) 为0.762,肝纤维化为0.664.

77
Cardiac biomarkers are critical in diagnosing, prognosing, and managing cardiovascular diseases. Routine measurement of specific biomarkers such as B-type natriuretic peptide (BNP), C-reactive protein (CRP), and homocysteine (Hcy) is common practice in clinical settings to evaluate heart function and predict cardiovascular events.
These markers indicate stress or strain on the heart muscle:
Natriuretic Peptides (BNP)
Cardiac myocytes produce these hormones in response to ventricular stretching...
