概括
腹腔透析 (PD) 患者的肺动脉高血压 (PAH) 与白细胞计数有关. 心肺运动测试 (CPET) 参数,特别是峰值代谢等价值 (METspeak),可以预测PD患者的PAH风险.
科学领域:
- 腎臟病學 (nephrology) 是一種醫學.
- 心脏病学 心脏病学
- 肺部病理学 肺部病理学
背景情况:
- 肺动脉高血压 (PAH) 在腹腔透析 (PD) 患者中显著增加死亡率.
- 心肺运动测试 (CPET) 测量心肺健康 (CRF) 并与死亡率相关.
- 在PD患者中,CPET对PAH的预测价值仍然未被探索.
研究的目的:
- 在PD患者中识别PAH的风险因素.
- 评估CPET参数对PAH发展的预测能力.
- 为PD中PAH的临床预防和管理策略提供指导.
主要方法:
- 对121名接受CPET的PD患者进行了回顾性分析.
- 患者分为PAH (n=39) 和非PAH (n=82) 组.
- 临床,实验室,超声波和CPET数据的比较;物流回归和ROC曲线分析.
主要成果:
- 升高的白细胞计数 (WBC) 是PAH的独立风险因素.
- 较高的氧气吸收峰值 (VO2峰值),厌氧值氧气吸收 (VO2AT),最高代谢等价量 (METspeak) 和最高功率负载 (WRpeak) 都具有保护作用.
- 在ROC分析中,METspeak显示了PAH的最高预测值 (AUC=0.719).
结论:
- 在PD患者中,PAH与WBC和CPET衍生的心肺呼吸能力参数有关.
- CPET参数,特别是METspeak,对PD患者的PAH具有显著的预测价值.
- 这些发现为PD中PAH的临床风险分层和管理提供了基础.

Oxygen therapy has emerged as a significant tool in enhancing the quality of life for patients suffering from pulmonary arterial hypertension (PAH). While this therapy has principally been studied on patients with significant hypoxemia, this therapeutic approach helps prevent potential organ damage and can be administered in the comfort of one's home.
Oxygen therapy is vital in increasing and maintaining blood oxygen levels in PAH patients. As a result, it aids in reducing fatigue,...

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...
