概括
持续的心率变化 (HRV) 监测没有预测肺动脉高血压 (PAH) 或治疗反应的恶化. 然而,休息和睡眠心率升高确实预测了PAH患者的临床恶化.
科学领域:
- 心脏病学 心脏病学
- 肺部医学 肺部医学
- 生物医学工程 生物医学工程
背景情况:
- 休息心率用于肺动脉高血压 (PAH) 的风险评估.
- 在家进行心率变化 (HRV) 监测,可以提供有关PAH生理变化的早期见解.
- 该研究探讨了HRV作为治疗响应指标和PAH中结果预测器的潜力.
研究的目的:
- 调查是否为期7天的连续家庭HRV监测是PAH的治疗反应指标.
- 为了确定HRV监测是否与PAH患者的临床结果有关.
- 为了比较稳定的PAH患者和接受治疗强化的人之间的HRV和心率变化.
主要方法:
- 罗切斯特大学的一项前性观察性研究,涉及罗切斯特大学24名PAH患者.
- 患者在基线和随访时接受了为期7天的连续心电图监测 (MC10生物标记).
- 数据包括休息和睡眠心率和HRV,活动期间不包括在分析中.
主要成果:
- 在基线或随访时,稳定和治疗强化PAH组之间没有发现心率或HRV的显著差异.
- 从基线到随访期间心率的变化在两组之间没有显著差异.
- 休息和睡眠心率升高,但不是HRV,预测了2年的临床恶化 (住院治疗,腹腔治疗或死亡).
结论:
- 与功能测试相比,在家中持续7天的HRV监测似乎没有提高PAH评估.
- 休息和睡眠时心率升高预示着PAH的临床恶化.
- 功能测试可能是评估PAH治疗反应和临床风险的更有效方法.

Pulmonary Hypertension: Classification and Pathogenesis
147
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...

Treatment for Pulmonary Arterial Hypertension: Oxygen Therapy for Respiratory Failure
166
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,...

Pulse
418
When the heart pumps blood out, arterial elastic fibers play a crucial role in sustaining a high-pressure gradient. They expand to accommodate the received blood and then recoil - a process known as the pulse that can be either manually palpated or electronically quantified. Despite a reduction in its effect with increased distance from the heart, elements of the pulse's systolic and diastolic components persist, observable even at the arteriole level.

Factors Influencing Heart Rate
2.3K
The heart rate, or pulse rate, is a vital indicator of cardiovascular health. It reflects the number of times the heart beats per minute. Various physiological and environmental factors influence heart rate, increasing or decreasing cardiac output. Understanding these factors is crucial for assessing heart function and identifying potential health issues.
Let us explore the significant factors affecting heart rate, including age, body temperature, posture, acute pain, chemical influences,...

Measurement of Blood Pressure
822
Assessing blood pressure is a standard procedure executed in virtually all medical environments. The method utilized today was established over a hundred years ago by an innovative Russian doctor, Dr. Nikolai Korotkoff. The soft ticking noise, known as Korotkoff sounds, heard while taking blood pressure readings results from turbulent blood flow within the vessels. The apparatus required for this procedure includes a sphygmomanometer, a blood pressure cuff attached to a gauge, and a...

Regulation of Pulse
1.2K
Pulse regulation involves physiological mechanisms that ensure adequate blood flow throughout the body. The heartbeat, regulated by the autonomic nervous system, is influenced by hormonal balance, physical activity, and emotional state.
