概括
炎症标志物C-反应蛋白 (CRP) 的升高与高血压患者患主要心血管不良事件 (MACE) 的风险增加有关,即使控制了静缩血压 (SBP). 这表明炎症在残留心血管风险中起作用.
科学领域:
- 心血管医学 心血管医学
- 炎症研究 炎症研究
- 公共卫生 公共卫生
背景情况:
- 压缩性血压 (SBP) 控制对于预防高血压中主要不良心血管事件 (MACE) 至关重要.
- 然而,在许多高血压患者中,仍然存在残留MACE风险,SBP受控,其潜在机制尚不清楚.
- 由C反应蛋白 (CRP) 表示的全身炎症是这种残留风险的潜在贡献者.
研究的目的:
- 调查高CRP水平和MACE残留风险在高血压患者中与控制的SBP之间的关联.
- 确定CRP是否在这个人群中是MACE的独立预测因子.
- 探索CRP水平和SBP控制对MACE风险的相互作用.
主要方法:
- 利用了来自英国生物库研究的数据,包括200,243名社区居住的高血压患者,没有基线心血管疾病.
- 基线CRP被归类为正常 (<2 mg/L) 或升高 (≥2 mg/L),SBP为<120,120-129,130-139和≥140 mmHg.
- 评估了MACE (冠心病,心肌梗塞,中风,心血管死亡的综合性) 的初级结局,平均随访时间为12.4年.
主要成果:
- 40.4%的参与者患有CRP水平升高 (≥2 mg/L).
- 在高CRP组中观察到MACE的发病率较高 (12.01对9.27每1000人年).
- 升高的CRP与17%更高的MACE调整风险相关,特别重要的是SBP在120-139 mmHg之间,独立于抗高血压治疗.
结论:
- 升高的CRP与高血压患者的残留MACE风险有显著的关联,即使是控制的SBP.
- 系统性炎症可能是驱动心血管事件的关键因素.
- 作为一个潜在的治疗目标,CRP值得进一步研究,以减轻高血压中的残留心血管风险.

Blood Studies for Cardiovascular System II: CRP, Hcy, and Cardiac Natriuretic Peptide Markers
682
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...

Coronary Artery Disease I: Introduction
1.4K
Coronary Artery Disease (CAD): An Overview with Scientific InsightsCoronary Artery Disease (CAD), often referred to as C-A-D, is a prevalent blood vessel disorder classified under the broader category of atherosclerosis. Atherosclerosis is a pathological process characterized by the hardening and narrowing of arteries due to the accumulation of atherosclerotic plaques. These plaques are composed of cholesterol, fatty substances, inflammatory cells, calcium, and fibrin, reducing blood flow to...

Hypertension and Regulation of Blood Pressure
4.6K
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...

Atherosclerosis III: Management
541
Management of atherosclerosis involves an integrated strategy encompassing pharmacological treatment, surgical interventions, lifestyle changes, and nutrition therapy to address the multifactorial nature of the disease.Pharmacological TherapyA cornerstone of atherosclerosis management is the use of pharmacological agents. Statins, such as atorvastatin, are pivotal in inhibiting HMG-CoA reductase, an enzyme that catalyzes an initial step in cholesterol synthesis in the liver. This reduction in...

Hypertension II: Pathophysiology
1.3K
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,...

Psychoneuroimmunology: Cardiovascular Disease
644
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...
