概括

通过CT扫描测量的腹周长 (AC) 和其与骨盆周长 (ACPC) 的比率更好地预测骨科患者的心脏代谢风险,而不是BMI. 这些成像指标提供了更好的风险分层,特别是在体重较高的人群中.

科学领域:

放射学和成像学放射学和成像学
代谢健康代谢健康
整形外科手术整形外科手术

背景情况:

体重指数 (BMI) 是标准的肥胖度量,但不反映脂肪分布.
中枢脂肪率与手术复杂性和代谢风险有关,使得BMI不足以进行手术前评估.
为了准确的患者风险分层,需要客观的身体成分指标.

研究的目的:

为了比较CT衍生的腹周长 (AC) 和腹周长 (ACPC) 比率与心脏代谢并发症的BMI的预测能力.
评估这些放射测量在接受手术的骨科患者中的有用性.

主要方法:

在134名骨科手术患者的回顾性队列研究中.
对手术前腹腔皮层CT扫描进行分析,以测量AC,骨盆周长和BMI.
使用后勤回归和ROC分析,测量身体成分与心脏代谢状况 (糖尿病,高血压) 和脂质谱的相关性.

主要成果:

腹部周长 (AC) 与糖尿病和高血压的关联最强.
与BMI相比,AC和ACPC比率显示出优异的预测性能,特别是在BMI>30 kg/m2的患者中.
与BMI不同的是,ACPC比率与高密度脂蛋白和甘油三水平有显著的相关性.

结论:

放射性AC和ACPC比率是中央脂肪和心脏代谢风险的有效指标.
这些基于成像的指标可能会在骨科手术中增强术前风险分层,特别是在超重患者中.
AC和ACPC比率为优化各种外科和医疗领域的患者护理提供了实用,客观的工具.

Imaging Studies for Cardiovascular System VI: Calcium -Scoring CT

Calcium-Scoring CT ScanA calcium-scoring CT scan, also known as coronary artery calcium (CAC) scan, detects calcium deposits in the coronary arteries. This test assesses the risk of coronary artery disease (CAD), which can lead to cardiovascular events such as angina, heart failure, and sudden cardiac arrest.A calcium-scoring CT scan is generally recommended for individuals at intermediate risk of CAD without symptoms. It includes:Men aged 40-75 and women aged 50-75: Especially those with a...

Drug Dosing: Obese Patients

Drug Dosing: Obese Patients

In the United States, obesity is a prominent concern. It is linked to heightened mortality rates due to increased occurrences of conditions such as hypertension, atherosclerosis, coronary artery disease, and diabetes compared to nonobese individuals. A patient is classified as obese if their actual body weight surpasses the ideal or desirable body weight by 20%, based on Metropolitan Life Insurance Company data. Ideal body weights consider average weights and heights for males and females...

Radiological Investigation I: X-ray and CT

Radiological investigations, including X-rays and computed tomography (CT) scans, are critical for diagnosing and evaluating various medical conditions. These imaging techniques provide valuable insights into the body's internal structures, aiding in the detection of abnormalities, assessment of disease progression, and development of treatment strategies. This article delves into two primary radiological investigations, chest X-rays and CT scans, outlining their purpose, procedures, and...
