概括
老年人患有高动脉样硬化心血管疾病 (ASCVD) 风险 (≥7.5%),但没有传统的风险因素仍然面临着显著增加的ASCVD事件发生率. 这凸显了需要仔细评估风险,而不仅仅是已确定的因素.
科学领域:
- 心血管医学 心血管医学
- 流行病学 流行病学
- 预防性心脏病学 预防性心脏病学
背景情况:
- 年龄是10年预测动脉样硬化心血管疾病 (ASCVD) 风险的主要决定因素.
- 一些老年人预计ASCVD风险≥7.5%,尽管缺乏确定的风险因素.
研究的目的:
- 为了比较ASCVD事件发生率在预测10年ASCVD风险≥7.5%的成年人中 (既有且没有确定的风险因素).
- 将ASCVD发病率与预测风险<7.5%的成年人进行比较.
主要方法:
- 从研究中风的地理和种族差异原因 (REGARDS) 的数据分析.
- 纳入标准:45-79岁,以前没有ASCVD或糖尿病,不服用他类药物,LDL胆固醇70-189 mg/dL.
- 分类为三组:预测风险<7.5%,具有已确定的风险因素的风险≥7.5%,没有已确定的风险因素的风险≥7.5%.
主要成果:
- 在11.1年的时间里,911事件ASCVD事件发生在11,115名参与者中.
- 每1000人年中ASCVD发病率为3.6 (风险<7.5%),12.8 (具有风险因素的≥7.5%) 和9.8 (没有风险因素的≥7.5%).
- 与<7.5%风险组相比,发生ASCVD的危险比率为3.58 (具有风险因素的≥7.5%) 和2.72 (没有风险因素的≥7.5%).
结论:
- 预测10年ASCVD风险≥7.5%但没有确定的风险因素的成年人表现出高发症ASCVD.
- 这一发现强调了考虑预测风险较高的个体的重要性,即使没有传统的风险因素.

Ischemic Heart Disease: Overview
1.3K
Ischemic heart disease occurs when the heart's blood supply dwindles, causing an ominous lack of oxygen and nutrients. This deficiency, stemming from reduced or obstructed blood flow, spells danger, leading to heart muscle damage and dysfunction.
Atherosclerosis, the primary malefactor, orchestrates this dangerous condition. It manifests as the accumulation of fatty deposits, akin to insidious plaques, within arterial walls. As time elapses, these plaques metamorphose, hardening and...

Cardiovascular Drugs: Classification based on Therapeutic Indications
2.9K
Cardiovascular diseases, encompassing a range of conditions, can significantly affect the heart's operations and the overall circulatory system. These conditions impair the heart's ability to pump blood, leading to a deficit in oxygen supply to crucial organs. Anomalies in the heart's electrical system, known as arrhythmias, can cause heartbeats to accelerate or slow down. Usually, heart rates increase during physical activity and decrease while resting or sleeping. However,...

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
Inquire about symptoms...

Exercise and Cardiovascular Response
820
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...

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...

Blood Studies for Cardiovascular System II: CRP, Hcy, and Cardiac Natriuretic Peptide Markers
94
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...
