概括
腹部肥胖和低HDL胆固醇是心血管事件的强有力的预测因素,在准确度上超过BMI. 这些因素有助于识别目前心血管风险分层工具所忽略的剩余风险.
科学领域:
- 心脏病学 心脏病学
- 代谢综合征是代谢综合征的一种.
- 预防医学 预防医学
背景情况:
- 心血管风险分层 (CVR) 在识别残留风险方面面临挑战.
- 腹部肥胖反映了代谢活跃的内脏脂肪组织,与炎症和动脉产生有关.
- 这项研究评估了心脏代谢风险因素,重点是腰围 (WC),用于预测主要不良心血管事件 (MACE).
研究的目的:
- 评估基线心脏代谢风险因素的预测价值,特别是腹部肥胖 (WC),对于发生的MACEs.
- 将WC的预测效用与传统的CVR得分 (FRS,SCORE2/SCORE2-OP) 和BMI定义的肥胖症进行比较.
- 确定关键的生物标志物,揭开残留心血管风险.
主要方法:
- 预期对736名门诊患者的随访,这些患者最初没有MACE.
- 基线评估包括人体测量,生化标志物,以及FRS和SCORE2/SCORE2-OP的计算.
- 腹部肥胖症按国际糖尿病联合会的标准定义为WC (男性≥94厘米,女性≥80厘米).
主要成果:
- 132名参与者 (17.9%) 在中位数为84.9个月的随访期间经历了MACE.
- 基线腹部肥胖 (78.1%) 与MACE (OR=1.784) 显著相关,与BMI定义的肥胖不同.
- 在多变量分析中,低HDL胆固醇和腹部肥胖仍然是独立的预测因素 (p<0.001).
- "中等风险"SCORE2/SCORE2-OP类别的个体显示高的LDL-c,占MACE的最多.
结论:
- 腹部肥胖和低HDL胆固醇是心血管事件的强大,独立的预测因素.
- 这些标志物在识别有风险的个体方面优于BMI等传统指标.
- WC和HDL-c对于检测当前分层模型遗漏的残留心血管风险至关重要.

Coronary Artery Disease I: Introduction
55
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...

Atherosclerosis III: Management
35
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...

Coronary Artery Disease IV: Preventive Measures
32
Effective preventive measures for coronary artery disease (CAD) focus on controlling modifiable risk factors, including cholesterol abnormalities and lifestyle changes.Cholesterol ManagementFirst, the Mediterranean diet and the American Heart Association advocate for maintaining low-density lipoprotein (LDL) cholesterol levels below 100 mg/dL, with a more stringent recommendation of below 70 mg/dL for individuals at high risk. LDL cholesterol, often termed "bad cholesterol," can lead to the...

Cholesterol: Significance and Regulation
686
Although not a source of energy, cholesterol plays a significant role as a foundational structure for bile salts, steroid hormones, and vitamin D, as well as being a crucial component of plasma membranes. Approximately 15% of blood cholesterol is derived from our diet, with the remainder synthesized from acetyl CoA by the liver and intestines. Cholesterol is eliminated from the body through its conversion into bile salts, which are eventually discarded in the feces.

Imaging Studies for Cardiovascular System VI: Calcium -Scoring CT
119
Calcium-Scoring CT ScanA calcium-scoring CT scan, also known as coronary artery calcium (CAC) scan, detects calcium deposits in the coronary arteries. This test assesses the risk of coronary artery disease (CAD), which can lead to cardiovascular events such as angina, heart failure, and sudden cardiac arrest.A calcium-scoring CT scan is generally recommended for individuals at intermediate risk of CAD without symptoms. It includes:Men aged 40-75 and women aged 50-75: Especially those with a...

Assessment of the Cardiovascular System I: Subjective Data
467
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...
