Biopsychosocial science and medicine
|January 22, 2026
概括
患有心力衰竭,排气率降低 (HFrEF) 和冠状动脉疾病 (CAD) 的人对心理压力表现出异常反应. 这些包括血压变化减弱,血管收缩增加,炎症和祖细胞调动,表明长期结果较差.
科学领域:
- 心脏病学 心脏病学
- 免疫学 免疫学 免疫学
- 生理学 生理学 生理学
背景情况:
- 稳定性冠状动脉疾病 (CAD) 影响着全世界数以百万计的人.
- 减少喷射分数 (HFrEF) 的心力衰竭是CAD的常见并发症.
- 了解患有HFrEF和没有HFrEF的CAD患者的压力反应对于风险分层至关重要.
研究的目的:
- 研究患有稳定CAD的个体对急性精神压力的生理和免疫反应.
- 为了比较患有心力衰竭和没有心力衰竭的患者之间的这些反应,减少排气分数 (HFrEF).
主要方法:
- 一组313名患有稳定的CAD的人 (45名患有HFrEF) 接受了基于实验室的心理压力测试.
- 血液动力学反应 (静脉压变化) 和血管收缩 (外周动脉度) 被评估.
- 通过测量干白素-6 (IL-6) 水平和循环原生细胞计数来评估免疫功能.
主要成果:
- 患有HFrEF的患者在压力期间表现出缩的缩性血压增加 (30.4 mmHg与41.9 mmHg相比) 和更大的血管收缩 (PAT比率0.69与0.83).
- 在HFrEF患者中,IL-6水平 (0.91比0.42ppg/ml) 和循环原生细胞 (0.68比0.22细胞/L) 的增加显著更高.
- 这些不适应应激反应在调整风险因素后仍然与HFrEF独立相关.
结论:
- 稳定的CAD患者中HFrEF的存在与精神压力期间明显的不良生理和免疫反应有关.
- 这些包括血压调节受损,血管收缩增加,炎症增加,以及增强的原始细胞调动.
- 在HFrEF患者中,这些由压力引起的变化与较差的长期健康结果有关.

Stress and Mental Health
846
Chronic stress profoundly affects mental health, significantly influencing mood, behavior, and overall quality of life. Research closely links chronic stress with mental health conditions such as depression, anxiety, and substance use disorders. Ongoing exposure to stress can lead to physiological and psychological changes, initiating a cycle of emotional distress and maladaptive coping mechanisms.

Responses to Salt Stress

Salt stress—which can be triggered by high salt concentrations in a plant’s environment—can significantly affect plant growth and crop production by influencing photosynthesis and the absorption of water and nutrients.

Responses to Heat and Cold Stress
14.7K
Every organism has an optimum temperature range within which healthy growth and physiological functioning can occur. At the ends of this range, there will be a minimum and maximum temperature that interrupt biological processes.

Exercise significantly impacts cardiovascular response, which is crucial for understanding patient health and designing effective treatment plans.
Light to moderate physical activity initiates a series of interconnected responses in the body. The heart rate modestly increases in anticipation of the workout, followed by widespread vasodilation as oxygen consumption by skeletal muscles increases. This results in decreased peripheral resistance, increased capillary blood flow, and accelerated...

Stress Response System
712
The stress response system, also known as the fight-or-flight response, is the body's automatic physiological reaction to perceived threats. Hans Selye introduced the concept of General Adaptation Syndrome (GAS) to describe the predictable pattern of changes that occur in response to stress. GAS consists of three sequential stages: alarm, resistance, and exhaustion. This model helps explain how chronic stress can contribute to health problems.

Anatomy of the Circulatory System
97.8K
The human circulatory system consists of blood, blood vessels that carry blood away from the heart, around the body, and back to the heart, and the heart itself, which acts as a central pump. The systemic circuit supplies blood to the whole body, the coronary circuit supplies blood to the heart, and the pulmonary circuit supplies blood flow between the heart and lungs.
