概括
肺血栓内切除术 (PTE) 后,TAPSE和S'等心声测量可能不可靠. 手术后的RV大小,体积,RVEF和TR严重程度更好地表明CTEPH的PTE后的RV恢复.
科学领域:
- 心脏病学 心脏病学
- 心声回声图 (Echocardiography) 是一种心声回声图.
- 肺高血压是什么意思 肺高血压
背景情况:
- 传统的对右心室 (RV) 功能的回声心脏学测量,如三环状平面心缩外流 (TAPSE) 和心缩速度峰值 (S'),在心脏手术后可能不可靠.
- 手术后的负载条件和心肌力学变化可能会影响这些标准RV功能评估的准确性.
研究的目的:
- 在慢性血栓栓塞性肺高血压 (CTEPH) 肺血栓内膜切除术 (PTE) 后评估右心室 (RV) 功能.
- 为了确定更准确地反映术后RV恢复的替代回声心脏学指数.
主要方法:
- 对接受PTE的CTEPH患者进行了回顾性单中心研究.
- 在手术前和手术后3个月内进行心声评估.
- 评估RV的大小,功能,体积,肺压力和三腹吐 (TR) 的严重程度.
主要成果:
- 在术后,TAPSE和RV S'显著下降 (p < 0.001).
- RV大小,终端透缩体积 (RVEDV) 和终端抽缩体积 (RVESV) 均下降 (p < 0.05).
- 2D RV喷射分数 (RVEF) 显著增加 (+7%,p = 0.003),TR严重程度有所改善 (p = 0.003).
结论:
- 在PTE后,RV大小,体积,RVEF和TR严重程度是RV恢复的更可靠指标,而不是TAPSE或S'.
- 研究结果表明,由于降低后载荷,可以逆向RV改造.
- 传统的纵向RV功能指标在术后环境中存在局限性.

Pulmonary Hypertension: Classification and Pathogenesis
670
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...

Chronic Obstructive Pulmonary Disease
2.6K
COPD is defined as a heterogeneous lung condition marked by persistent respiratory symptoms such as dyspnea, cough, and sputum production, caused by abnormalities in the airways that cause airflow obstruction.
Smoking is a primary risk factor for COPD, with over 80% of patients having a history of it. Patients typically experience progressive dyspnea or labored breathing, frequent coughing, and recurrent pulmonary infections. Many eventually succumb to respiratory failure, characterized by...

Pulmonary Function Tests (PFTs)
Pulmonary Function Tests are crucial diagnostic tools for assessing respiratory function, particularly in patients with chronic respiratory disorders. They comprehensively evaluate lung volumes, ventilatory function, breathing mechanics, diffusion, and gas exchange. These tests help diagnose pulmonary diseases and play a significant role in monitoring disease progression, evaluating disability, and assessing response to therapy.
PFTs involve using a spirometer, a...

Chronic Obstructive Pulmonary Disease-I: Introduction
3.9K
Chronic Obstructive Pulmonary Disease (COPD) is a long-lasting respiratory condition requiring continuous attention and care. It is a progressive lung disease that leads to breathing challenges due to airflow obstruction. It manifests as persistent respiratory symptoms and restricted airflow resulting from abnormalities in the airways and alveoli, usually due to long-term exposure to harmful particles or gases. COPD mainly consists of two primary conditions: emphysema and chronic bronchitis.

Managing Chronic Obstructive Pulmonary Disease (COPD) involves a multifaceted approach to reduce symptoms, prevent exacerbations, improve overall health status, and slow disease progression. Key strategies include lifestyle modifications, pharmacotherapy, supportive therapies, and, in some cases, surgery. Here is an overview of the primary COPD management strategies:
