概括
肺栓塞 (PE) 后持续的肺 perfusion 缺陷表明患有慢性血栓栓塞性肺病 (CTEPD) 的风险. 早期心肺运动测试 (CPET) 和应激心声图 (ESE) 可以预测右心室 (RV) 功能障碍和运动诱导的肺高血压 (ExPH).
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:
- 慢性血栓栓塞性肺病 (CTEPD) 可以在急性肺栓塞 (PE) 后发展,导致持续的输液缺陷和肺血管功能障碍.
- 右心室 (RV) 损伤和运动诱导的肺高血压 (ExPH) 是显著的并发症,即使在抗凝药治疗.
研究的目的:
- 评估患者的临床,血液动力学和功能演变,选CTEPD与持续的肺 perfusion 缺陷.
- 在后PE患者中确定VR损伤和ExPH的非侵入性预测因子.
主要方法:
- 分析了55名患有PE病史的患者,通过肺 perfusion scintigraphy (Q-scan) 在4个月后进行分层.
- 在基线和随访时利用心声谱,心肺运动测试 (CPET) 和运动应激心声谱 (ESE).
- 临床评估和静止心电回声学重复至48个月.
主要成果:
- 患有持续的Q扫描缺陷 (Q阳性) 的患者在基线显示较高的NT-proBNP和PESI得分.
- 4个月后,Q阳性患者在CPET和ESE上有较高的ExPH流行率 (p < 0.001).
- 在48个月后,Q阳性患者表现出持续的RV-PA脱,由较高的PAP,较低的TAPSE/sPAP比率和改变的RV外流通道加速时间表明.
结论:
- 在PE后持续的Q扫描缺陷确定了长期VR功能障碍和ExPH的风险人口,独立于休息期肺高血压.
- 4个月CPET和ESE提供了有价值的预后信息,用于早期识别正在发展的肺血管疾病.
- 将CPET和ESE纳入后续策略可以帮助管理患有CTEPD并发症风险的患者.

Cardiac Catheterization II: Right Heart Catheterization
774
Right Heart Catheterization: An OverviewRight heart catheterization is an invasive diagnostic procedure that measures right-sided cardiac and pulmonary artery pressures, calculates cardiac output, and identifies intracardiac shunts. It provides detailed hemodynamic data essential for diagnosing and managing various cardiovascular conditions, such as pulmonary hypertension.Access SitesCommon access sites for right heart catheterization include the internal jugular vein in the neck region, the...

Pulmonary Hypertension: Classification and Pathogenesis
552
Pulmonary hypertension (PH) is a severe health condition in which the mean pulmonary arterial pressure increases to 25 mmHg or more, even when the body is at rest. This high pressure in the blood vessels that transport blood from the heart to the lungs can cause various symptoms, including shortness of breath, can lead to right heart failure, and significantly affect the overall quality of life.
There are various classifications for PH, each relating to different underlying causes and also...

Pulmonary Embolism II: Diagnostic Studies and Interprofessional Care

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...
