美国成年人的心脏代谢指数和充血性心力衰竭之间的关联:一个横截面研究
1Department of Clinical Nutrition, Tongde Hospital of Zhejiang Province, Hangzhou, China.
肥胖会增加充血性心力衰竭 (CHF) 的风险. 心脏代谢指数 (CMI) 和CMI-age是一种新型指标,显示出与心脏不全症的显著相关性,CMI-age显示出早期检测的优越预测能力.
科学领域:
- 心脏病学和公共卫生
背景情况:
- 肥胖是已知的充血性心力衰竭 (CHF) 的风险因素.
- 关于内脏肥胖和心血管疾病风险之间的联系的数据有限.
- 心脏代谢指数 (CMI) 已被提议作为心脏代谢风险的标记.
研究的目的:
- 探索CHF和心脏代谢指数 (CMI) 之间的关系.
- 调查CMI和一种新的CMI-年龄指数与CHF风险的关联.
- 评估CHF的CMI和CMI-age的预测性能.
主要方法:
- 使用NHANES数据 (2011-2018) 的横截面研究,共9008名参与者.
- CMI计算为甘油三/HDL-C ×体重与身高的比率 (WHtR).
- CMI-年龄计算为CMI × 年龄.
- 后勤回归和ROC曲线分析用于评估相关性和预测能力.
主要成果:
- 慢性心血管衰竭的总体患病率为3.31%.
- 在原油和调整模型中,CMI和CMI-age都显示出与CHF风险的正相关性.
- 与CMI (0.610) 相比,CMI-age在预测CHF时显示了ROC曲线 (0.697) 下的区域显著更高.
结论:
- CMI和CMI年龄独立地与心血管疾病风险相关.
- CMI-age为CHF预防和管理提供了宝贵的见解.
- 在初级保健和资源有限的环境中,CMI-age可以成为识别CHF的有效工具.

Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...
