概括
白血细胞 (WBC) 计数与心脏骤停 (CA) 幸存者的一年死亡率有关. 非常高和非常低的白细胞计数都表明死亡风险增加,最低的风险接近正常范围的上限.
科学领域:
- 心脏病学 心脏病学
- 关键护理医学 关键护理医学
- 免疫学 免疫学 免疫学
背景情况:
- 系统性炎症是对缺血-再输液损伤的反应,可以使心脏骤停 (CA) 患者的复苏后护理复杂化.
- 早期对白细胞 (WBC) 计数的评估可以提供对患者结果的见解.
研究的目的:
- 在一大群心脏骤停患者中调查早期白细胞计数和一年死亡率之间的关联.
- 为了确定与心脏骤停后死亡风险最低相关的最佳白血细胞范围.
主要方法:
- 来自芬兰国家ICU注册表的ICU治疗CA患者的多中心队列的回顾性分析.
- 利用局部估计的散射图平滑 (LOESS) 来建模24小时内最异常的白细胞计数与一年死亡率之间的关联.
- 采用多变量逻辑回归和线性回归用于独立关联和嵌套队列分析,包括自发循环回归 (ROSC) 延迟的影响.
主要成果:
- 在白细胞计数和死亡率之间观察到一个U形的关联,预测的死亡率最低为7.5 x 10 ^ 9 / L.
- 高 (≥7.5 x 10^9/L) 和低 (<7.5 x 10^9/L) 的WBC组都显示了一年死亡率增加.
- 较高的WBC独立地与高WBC组的死亡率增加有关 (OR1.03每10^9/L),而较低的WBC与低WBC组的死亡率增加有关 (OR0.88每10^9/L).
- 较长时间延迟ROSC与患有可震动节律的患者中较高的WBC相关.
结论:
- 早期的白细胞计数与心脏骤停幸存者的一年死亡率独立相关.
- 在WBC数量接近正常参考范围的上限的患者中,死亡风险最低.
- 虽然不是个人确定的预后工具,但白细胞计数支持人们理解过度炎症对心脏骤停后综合征有害.

Blood Studies for Cardiovascular System I: Cardiac Biomarkers
103
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...

Actuarial Approach
63
The actuarial approach, a statistical method originally developed for life insurance risk assessment, is widely used to calculate survival rates in clinical and population studies. This method accounts for participants lost to follow-up or those who die from causes unrelated to the study, ensuring a more accurate representation of survival probabilities.
Consider the example of a high-risk surgical procedure with significant early-stage mortality. A two-year clinical study is conducted,...

Structure and Function of Leukocytes
1.9K
An adult in good health typically has between 4,500 and 11,000 leukocytes, or white blood cells, per microliter of blood, which constitutes about 1% of the total blood volume. Unlike red blood cells, white blood cells contain a nucleus and other cellular organelles but do not have hemoglobin. Most white blood cells reside in connective tissues, particularly in lymphatic organs such as the lymph nodes, with only a small fraction present in circulating blood.
