概括

在心力衰竭患者中,低体重指数 (BMI) 伴随着缓冲症表明预后更差. 隐藏的生物标志物,而不仅仅是BMI,可能会解释心力衰竭死亡率中的肥胖悖论.

科学领域:

心脏病学心脏病学
代谢综合征是代谢综合征的一种.
临床营养学临床营养学

背景情况:

肥胖是一种已知的心力衰竭 (HF) 的风险因素.
然而,肥胖与现有HF患者的较低死亡率有悖论的关联.
这种"肥胖悖论"可能会受到非测量条件的影响,比如缓冲症.

研究的目的:

调查急性心力衰竭 (HF) 中身体质量指数 (BMI) 和缓解症的预后意义.
确定卡塞克斯生物标志物是否可以澄清HF死亡率中的肥胖悖论.

主要方法:

从一个多中心注册表对3314名急性心力衰竭患者的回顾性分析.
根据体重指数 (BMI) 分类的患者:低 (<20 kg/m2),正常 (20-25 kg/m2) 和高 (≥25 kg/m2).
由低BMI (<20 kg/m2) 加上生化异常 (白蛋白,血红蛋白,C反应蛋白) 定义的. 卡切克生物标志物识别了患有这些异常的患者.

主要成果:

较高的BMI与全因死亡率的降低有关 (调整后危险比率[HR],0.92).
低BMI与缓冲症显示出最糟糕的预后;低BMI没有缓冲症的预后与正常BMI相似.
在所有BMI类别中,Cachectic生物标志物预测了更高的2年全因死亡率,特别是在高BMI患者中 (调整HR,3.60).

结论:

体重指数 (BMI) 可能作为心力衰竭的替代标志物.
隐性生物标志物似乎更准确地反映了潜在的条件.
这些生物标志物可能是理解心力衰竭中肥胖悖论的关键.

Blood Studies for Cardiovascular System II: CRP, Hcy, and Cardiac Natriuretic Peptide Markers

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...

Blood Studies for Cardiovascular System I: Cardiac Biomarkers

Cardiac biomarkers are enzymes, proteins, and hormones released into the blood when cardiac cells are injured. They are powerful tools for triaging.
The essential diagnostic tools for detecting myocardial necrosis and monitoring individuals suspected of having acute coronary syndrome (ACS) include:
Troponins
Troponins, particularly cardiac troponins I and T, are the most precise and sensitive markers of myocardial injury. They are detectable within 4-6 hours of myocardial injury and remain...

Pathophysiology of Heart Failure

1.5K

Heart failure (HF) is a progressive syndrome involving ventricles that leads to inadequate cardiac output. It can be classified based on location and output or ejection fraction. Ejection fraction (EF) is an essential measurement in the diagnosis and surveillance of HF. Reduced EF corresponds to systolic heart failure (HFrEF). However, HF with preserved ejection fraction (HFpEF) is becoming increasingly prevalent. Also known as diastolic HF, this form of HF is related to aging. The...

Obesity

371

The Body Mass Index (BMI) is a numerical value derived from a person's weight and height, used to categorize individuals into weight ranges. It is calculated using the formula: weight in kilograms divided by height in meters squared. Obesity is a health condition characterized by excessive accumulation of adipose tissue that poses health risks, often diagnosed with a BMI ≥ 30. This excess fat storage occurs when surplus dietary calories are converted into triglycerides and stored in...

Imbalances in Cardiac Output

1.3K

The heart's primary function is to pump blood throughout the body, maintaining a balance between blood sent out (cardiac output) and blood returning (venous return). If this balance is disrupted, it can result in congestive heart failure (CHF), a severe condition where the heart becomes an inefficient pump, leading to inadequate blood circulation.
CHF can occur due to the failure of either side of the heart. Left-side failure leads to pulmonary congestion—the right side continues to send...
