概括
右心室功能障碍可能发生在肺栓塞 (PE) 和癌症治疗后. 这一案例表明,抗环素心脏毒性即使在PE恢复后也会导致RV衰竭,强调全面的心脏监测.
科学领域:
- 心脏病学 心脏病学
- 在瘤学瘤学.
- 心脏瘤学是一门专业.
背景情况:
- 右心室 (RV) 功能障碍与肺栓塞 (PE) 和癌症治疗心脏毒性有关.
- 人环素可以影响左心室和右心室,但它们对PE恢复后的RV的影响尚不清楚.
- 本案例检查了在PE诱导的应变和恢复后,RV对人环素心脏毒性的敏感性.
研究的目的:
- 介绍PE康复后由于人环素心脏毒性导致的RV衰竭的病例.
- 为了强调RV在PE后对心脏毒剂的脆弱性.
- 强调需要在心脏毒性评估中进行全面的VR监测.
主要方法:
- 一个41岁妇女的病例研究,患有复发性PE和肺动脉肉瘤.
- 使用跨胸腔心声扫描 (TTE),右心导管,心血管MRI (CMR) 进行心脏评估.
- 监测RV和左心室 (LV) 功能在治疗前和治疗期间.
主要成果:
- 最初的PE导致了VR功能障碍,手术后得到解决.
- 在接受了 antracycline 化疗后,患者出现了渐进的 RV 扩张和功能障碍,随后出现了双心室衰竭.
- 尽管最初保留了 LV 喷射分数 (LVEF),但 RV 失效之前出现了明显的 LV 损害,导致双心脏失效.
结论:
- 人环素治疗可以诱导显著的RV功能障碍和失败,即使在患者之前的RV恢复.
- 目前专注于LV指标的心脏毒性指南是不够的;RV评估至关重要.
- 综合性心脏监测,包括彻底的RV评估,对于接受以环素为基础的疗法的患者至关重要.

Cardiomyopathy II: Dilated Cardiomyopathy
455
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,...

Pulmonary Embolism II: Diagnostic Studies and Interprofessional Care
298
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...

Pulmonary Embolism I: Introduction
492
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...

Pulmonary Embolism III: Nursing Management
347
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...

Cardiac Catheterization II: Right Heart Catheterization
786
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...

Cardiomyopathy IV: Restrictive Cardiomyopathy
439
Restrictive cardiomyopathy (RCM) is a rare heart muscle disease characterized by impaired ventricular filling due to stiffened ventricular walls, leading to significant diastolic dysfunction.EtiologyRestrictive cardiomyopathy can arise from both inherited and acquired diseases, many of which are systemic. It is categorized into four main types: infiltrative, storage, non-infiltrative, and endomyocardial diseases.Infiltrative diseases, such as amyloidosis, lead to RCM by depositing amyloid...
