概括
超短心率变化 (HRV) 可能有助于非瘤性肺栓塞 (PE) 患者的风险分层,但在瘤性PE病例中没有预后价值. 较低的HRV指数与非瘤性PE患者的生存率较差相关.
科学领域:
- 心脏病学 心脏病学
- 自主神经系统研究 自主神经系统研究
- 肺部医学 肺部医学
背景情况:
- 肺栓塞 (PE) 是心血管死亡的主要原因,需要准确的风险分层.
- 心率变化 (HRV) 是自主功能的指标,在心血管疾病中具有潜在的预后价值,但在PE中未得到充分研究.
- 在急诊室 (ED) 评估HRV可以为PE患者提供快速的预后见解.
研究的目的:
- 调查超短期HRV指数在预测急性PE患者死亡率方面的预后效用.
- 在瘤和非瘤PE患者亚组之间区分HRV的预后值.
- 探索HRV与PE中短期 (30天) 和中期 (90天) 死亡率之间的关联.
主要方法:
- 追溯队列研究包括233名在ED诊断急性PE的患者.
- 从10秒的心电图记录中计算超短HRV指数 (SDNN,RMSSD).
- 多变量逻辑回归和Cox生存分析,以评估HRV对死亡率的独立预测值,并对瘤患者进行亚组分析.
主要成果:
- 超短HRV指数与整体PE队列中的短期死亡率没有显著相关.
- 在非瘤性PE患者中,较高的SDNN独立地与90天死亡率的增加有关 (AOR 1.018,p=0.044).
- 癌症PE患者的HRV没有预测死亡率的价值;然而,较低的HRV与整体和非癌症组的生存率差相关,这一发现可能由适应性生理反应解释.
结论:
- 超短HRV显示了非瘤性PE患者短期风险分层的潜力.
- 在瘤PE患者中,HRV似乎没有短期预后相关性.
- 需要进一步的研究来理解矛盾的发现和适应性HRV在PE预后中的作用.

Diagnosing Pulmonary EmbolismDiagnosing pulmonary embolism (PE) involves clinical assessment and advanced imaging tests. The preferred diagnostic tool is the spiral (helical) CT scan or CT angiography (CTA), which uses intravenous contrast media to visualize the pulmonary vasculature and identify emboli.A ventilation-perfusion (V/Q) scan is an alternative for patients unable to receive contrast media. This scan includes both perfusion and ventilation scanning. Perfusion scanning involves...

01:29Pulmonary Embolism I: Introduction
1.0K
Pulmonary embolism (PE) occurs when a thrombus, fat or air embolus, amniotic fluid, or tumor tissue blocks one or more pulmonary arteries. These blockages originate in the venous system or the right side of the heart.EtiologyPE primarily arises from deep vein thrombosis (DVT) and other hypercoagulable states, such as inherited thrombophilias. Additional etiological factors include venous stasis, commonly seen in obesity, and endothelial injury from surgery and trauma. Less common causes include...

Diagnosing acute coronary syndrome or ACS begins with a thorough patient history. Notable symptoms include central, crushing chest pain radiating to the left arm, neck, jaw, or back, along with shortness of breath, sweating (diaphoresis), nausea, vomiting, dizziness, and palpitations.It is crucial to note any history of cardiac illnesses and assess risk factors, including age, gender, smoking, hypertension, diabetes, hyperlipidemia, and a sedentary lifestyle.During physical examination, vital...

A pulmonary embolism occurs when a thrombus, amniotic fluid, tumor tissue, fat, or air embolus blocks one or more pulmonary arteries. Effective nursing management and patient education are crucial for improving outcomes and preventing recurrence.Nursing management starts with obtaining a comprehensive patient history, particularly noting any history of deep vein thrombosis (DVT). Assess for clinical manifestations, including dyspnea, chest pain, crackles, heart murmurs, and signs of right-sided...

01:30Pulse rhythm
1.5K
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...
