- 血管生物学 血管生物学
- 神经科学是一个神经科学.
背景情况:
- 全球约有10%的人口是左撇子 (LH).
- 以前的研究表明,左撇子与寿命缩短之间存在潜在联系,以及糖尿病,癌症和心血管疾病 (CVD) 等疾病的风险增加.
研究的目的:
- 为了调查心脏病风险的关键指标血管功能和心率变化 (HRV) 是否在左撇子 (LH) 个体下降,与右撇子 (RH) 个体相比.
- 测试LH个体血管健康和HRV较差的假设,这表明对心血管疾病的倾向较高.
主要方法:
- 这项研究招募了379名年龄在18-50岁之间的参与者.

Lateralization
337
Brain lateralization refers to the division of mental processes and functions between the two hemispheres of the brain, a phenomenon that optimizes neural efficiency and underpins complex abilities in humans. This specialization allows each hemisphere to perform tasks where it has a comparative advantage, facilitating more refined cognitive capabilities across different domains.

Psychoneuroimmunology: Cardiovascular Disease
31
Psychoneuroimmunology (PNI) is a multidisciplinary field that examines how psychological factors, particularly stress, interact with the immune system and impact physical health. Research in PNI has shown that chronic or traumatic stress can disrupt both the hypothalamic-pituitary-adrenal axis and the sympathetic nervous system. These disruptions contribute to serious health conditions, including cardiovascular diseases.
A key area of focus in PNI is the relationship between stress and coronary...

Assessment of the Cardiovascular System II: Inspection
259
Inspection is the initial step in assessing the cardiovascular system. It involves a detailed visual examination that provides crucial information about a patient's circulatory and cardiac health. This systematic process, conducted from head to toe, helps identify signs of cardiovascular conditions by observing physical appearance, skin and mucous membranes, jugular and carotid pulsations, chest symmetry, and the condition of the extremities.

Assessment of the Cardiovascular System I: Subjective Data
343
A thorough health history and physical assessment are essential for identifying cardiovascular disease (CVD) symptoms and distinguishing them from other health issues.
Initial Enquiry
Ask the patient about their primary concern and thoroughly explore all reported symptoms.
Medical History
Investigate past illnesses affecting the cardiovascular system, such as angina, anemia, rheumatic fever, congenital heart disease, stroke, thrombophlebitis, dysrhythmias, varicosities
