概括
早期查免疫检查点抑制剂 (ICI) 诱导的心肌炎 (irMyocarditis) 使用高灵敏性心脏托罗-T (hs-TnT) 可以识别有风险的患者. 用皮质类固醇及时干预可以减少主要心血管不良事件和死亡率.
科学领域:
- 心脏病学 心脏病学
- 在瘤学瘤学.
- 免疫学 免疫学 免疫学
背景情况:
- 免疫检查点抑制剂 (ICI) 诱导的心肌炎 (irMyocarditis) 是一种罕见但严重的不良事件,与40-50%的死亡率相关.
- 肌心炎的诊断往往是在临床症状出现后的晚期发生的,这限制了治疗的有效性.
- 早期检测对于管理这种可能致命的疾病至关重要.
研究的目的:
- 用高灵敏性心脏托罗邦尼-T (hs-TnT) 来对接受ICI治疗的癌症患者进行前性查.
- 评估hs-TnT水平对于早期识别和irMyocarditis风险分层的有用性.
- 评估早期检测和干预对患者结果的影响.
主要方法:
- 280名癌症患者的队列被纳入了前性查研究.
- 在基线和每次ICI输液之前,测量了高灵敏性心脏托罗邦尼-T (hs-TnT) 水平.
- 患有hs-TnT升高的患者接受了进一步的心血管评估和诊断工作.
主要成果:
- 在ICI治疗期间,在27.6%的正常基线hs-TnT患者和66.7%的基线hs-TnT患者中观察到hs-TnT水平升高.
- 心血管评估和心肌炎诊断分别在11.2%和27.4%的患者中进行.
- 在接受皮质类固醇治疗的16名被诊断为irMyocarditis患者中,没有死亡事件发生;确定了检测的最佳hs-TnT值.
结论:
- 使用hs-TnT的前性查有效地识别了在治疗过程的早期患有irMyocarditis的患者.
- 早期检测可以及时中止ICI治疗和启动皮质类固醇,显著减少主要心血管不良事件和死亡率.
- 在接受ICI治疗的患者中,hs-TnT作为监测和管理irrMyocarditis的宝贵生物标志物.

Blood Studies for Cardiovascular System I: Cardiac Biomarkers
100
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...

Pulse rhythm
759
Pulse rhythm refers to the pattern of pulsations within specific intervals, offering valuable insights into the regularity or irregularity of the heart's beats as observed through the pattern of pulsation within specific intervals. A regular pulse exhibits a consistent heart rate with uniform waveforms and pulsation force, variations of which can be classified as normal, weak, or bounding.
Conversely, an irregular pulse pattern is termed dysrhythmia, stemming from disruptions in cardiac...
