概括
后急性COVID-19 (PASC) 患者经常由于氧气提取受损而经历运动不耐受. 侵袭性心肺运动测试显示,PASC中存在一种独特的心力衰竭,其中保留了射出分数表型,这表明外围限制了运动.
科学领域:
- 心脏病学 心脏病学
- 肺部病理学 肺部病理学
- 运动生理学 运动生理学
背景情况:
- COVID-19 (PASC) 后急性后续症状通常存在于运动不耐受性.
- 了解潜在的血液动力学异常对于有效的管理至关重要.
研究的目的:
- 在PASC相关的运动不耐受症中表征侵入性血液动力学异常.
- 为了研究心力衰竭与保留喷射分数 (HFpEF) 和肥胖在PASC运动限制中的作用.
主要方法:
- 对55名PASC患者进行了侵入性心肺运动测试 (iCPET) 和右心导管治疗.
- 与肥胖的非PASC对照组进行比较,以评估肥胖的贡献.
主要成果:
- 75%的PASC患者表现出受损的峰值氧气提取 (pEO2) 与超正常的心力输出.
- 大约25%的人患有中央心肺病理,包括HFpEF或肺高血压 (PH).
- 患有HFpEF的PASC患者表现出受损的pEO2和补偿的PH,肥胖是一个重要因素.
结论:
- 损伤的pEO2是PASC运动不耐受的一个关键因素,通常无法通过标准测试来解释.
- 在PASC中,一个独特的HFpEF表型与外周运动限制是普遍存在的.
- 在PASC患者中,监督康复并没有显著改变受损的pEO2.

Pathophysiology of Heart Failure
1.6K
Heart failure (HF) is a progressive syndrome involving ventricles that leads to inadequate cardiac output. It can be classified based on location and output or ejection fraction. Ejection fraction (EF) is an essential measurement in the diagnosis and surveillance of HF. Reduced EF corresponds to systolic heart failure (HFrEF). However, HF with preserved ejection fraction (HFpEF) is becoming increasingly prevalent. Also known as diastolic HF, this form of HF is related to aging. The...

Imbalances in Cardiac Output
1.4K
The heart's primary function is to pump blood throughout the body, maintaining a balance between blood sent out (cardiac output) and blood returning (venous return). If this balance is disrupted, it can result in congestive heart failure (CHF), a severe condition where the heart becomes an inefficient pump, leading to inadequate blood circulation.
CHF can occur due to the failure of either side of the heart. Left-side failure leads to pulmonary congestion—the right side continues to send...
