概括
在患有孕前症 (PE) 的女性中,血中胡卜素水平较低,这是怀孕期间的一种高血压疾病. 这表明氧化压力可能会耗尽这些抗氧化剂,使PE与其他妊娠高血压疾病区别开来.
科学领域:
- 产科和妇科 产科和妇科
- 营养科学 营养科学
- 心血管健康 心血管健康
背景情况:
- 妊娠高血压障碍 (HDP) 在全球范围内很常见,病因不明,但已知与氧化应激有联系.
- 胡卜素是必不可少的抗氧化营养素,可能在调节HDP中的氧化应激中发挥作用.
- 以前的研究将胡卜素状况与高血压联系起来,但与HDP全谱的关联不清楚.
研究的目的:
- 量化和比较不同妊娠高血压障碍 (HDP) 的胡卜素摄入量和血水平.
- 调查胡卜素状况和特定的HDP条件之间的关系,如妊娠高血压 (GH),慢性高血压 (CH) 和孕前 (PE).
主要方法:
- 一项前性队列研究,涉及488名在分娩时的孕妇.
- 数据收集包括哈佛食品频率问卷和血样本.
- 用高性能液态染色学质谱法 (HPLC-MS) 分析了等离子体中的胡卜素.
主要成果:
- 总, cis 和 trans-β 胡卜素的血水平在孕前 (PE) 中明显较低,相比于正常血压 (NT),慢性高血压 (CH) 和妊娠高血压 (GH) 组.
- 与NT相比,氨酸+天氨酸和β-氨酸在PE中减少,而β-氨酸在PE中也比GH更低.
- 与CH和GH相比,PE中的α-胡卜素水平较低.
结论:
- 血胡卜素水平在妊娠高血压疾病 (HDP) 中显著不同.
- 孕前 (PE) 与其他HDP相比,与循环中的胡卜素水平较低有关.
- 结果表明,PE中的氧化应激可能会耗尽循环中的胡卜素,使其与其他HDP区别开来.

Hypertension III: Clinical Manifestations and Diagnostic Studies
465
Hypertension is asymptomatic and also referred to as the "silent killer" until it progresses to a severe stage or causes target organ disease. Patients may experience symptoms stemming from the strain on blood vessels and tissues in various organs or the heart's increased workload.Physical exams might show no abnormalities other than high blood pressure. Signs of vascular damage, when present, correspond to the organs supplied by the affected vessels, leading to target organ damage. For...

Hormonal Regulation
35.7K
The renin-aldosterone system is an endocrine system which guides the renal absorption of water and electrolytes, thus managing blood pressure and osmoregulation. Activation of the system begins in the kidneys with a small cluster of cells adjacent to the afferent and efferent blood vessels of the renal corpuscle. As the nephrons are filtering blood, juxtaglomerular cells monitor blood pressure. If they detect a decrease in pressure, they release the hormone renin into the bloodstream.

Blood Studies for Cardiovascular System II: CRP, Hcy, and Cardiac Natriuretic Peptide Markers
535
Cardiac biomarkers are critical in diagnosing, prognosing, and managing cardiovascular diseases. Routine measurement of specific biomarkers such as B-type natriuretic peptide (BNP), C-reactive protein (CRP), and homocysteine (Hcy) is common practice in clinical settings to evaluate heart function and predict cardiovascular events.
These markers indicate stress or strain on the heart muscle:
Natriuretic Peptides (BNP)
Cardiac myocytes produce these hormones in response to ventricular stretching...

Hypertension and Regulation of Blood Pressure
3.7K
Hypertension, the most common cardiovascular disease, is diagnosed through repeated measurements of elevated blood pressure. Its risks, including damage to the kidney, heart, and brain, are directly proportional to blood pressure levels. Starting from 115/75 mm Hg, the risk of cardiovascular disease doubles with each increment of 20/10 mm Hg. The diagnosis relies on blood pressure measurements, not on patient symptoms, as hypertension is often asymptomatic until end-organ damage is imminent or...

Hypertension II: Pathophysiology
781
Hypertension is a chronic condition in which the blood's force against artery walls is excessively high, posing risks such as heart disease. The condition's underlying mechanisms involve complex interactions among the cardiovascular, kidney, and autonomic nervous systems.Renin-Angiotensin-Aldosterone System (RAAS): This system significantly influences blood pressure regulation. When blood pressure decreases, the kidneys secrete renin. This enzyme transforms angiotensinogen, a plasma protein,...

Hypertension V: Nursing Management
355
The nursing management of hypertension involves accurately assessing symptoms, making a comprehensive nursing diagnosis, collaborating with patients to set goals, and implementing targeted interventions to mitigate the condition's impact and improve patient well-being.Comprehensive AssessmentThe initial step in nursing care for hypertension involves a thorough patient assessment. It includes evaluating symptoms such as headaches, dizziness, blurred vision, and previous hypertension episodes.
