概括
在急性肺栓塞 (PE) 中,右心室功能障碍 (RVD) 的心声学参数预测死亡. 在心声学上结合至少两个RVD参数,可以确定PE患者的死亡风险较高.
科学领域:
- 心脏病学 心脏病学
- 肺部病理学 肺部病理学
- 医疗成像医学成像
背景情况:
- 心声学对于评估急性肺栓塞 (PE) 中的右心室功能障碍 (RVD) 至关重要,以指导风险分层和治疗.
- 个人RVD心声学参数及其在急性PE中的组合的预后意义仍然不清楚.
研究的目的:
- 确定个人RVD心声学参数与短期所有原因和PE相关死亡率之间的关联.
- 评估RVD参数的组合是否增加急性PE患者的风险分层.
主要方法:
- 进行了个体患者数据元分析 (IPDMA),汇集了研究中的数据,研究了急性PE患者的心声学发现和30天死亡率.
- 包括的结果是短期所有原因和PE相关的死亡.
主要成果:
- 在9,233名患者中,7%的人经历了短期死亡. 单变分析显示TAPSE<16mm,PAP>30mmHg,RV-to-LV比率>1,RV低运动,悖论性隔膜运动和RV扩张与死亡率有关.
- 虽然一个异常的RVD参数与死亡无关,但两个 (OR 1.52) 或三个或更多 (OR 2.33) 显著增加了死亡风险.
- RV-to-LV比率>1和TAPSE<16mm的组合显示出死亡率增加的趋势 (OR 2.49).
结论:
- 通过心声学评估的个别RVD参数与急性PE的死亡率有关.
- 至少有两个异常RVD参数的存在有效地识别了急性PE患者的死亡风险增加.

464
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 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...

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...

Dilated cardiomyopathy, or DCM, is a progressive myocardial disorder characterized by ventricular chamber dilation and contractile dysfunction.EtiologyVarious factors can cause DCM, including hypertension and heavy alcohol intake, which contribute to the weakening and enlargement of the heart muscle. Viral infections, such as Coxsackievirus B, adenoviruses, and influenza, can lead to DCM by causing inflammation and damage to heart tissue. Certain chemotherapeutic agents, including daunorubicin,...
