まとめ
閉経は主として60歳未満の女性において,動脈硬化性心血管疾患 (ASCVD) のリスクを増加させる. これは中年期における 標的型予防戦略の必要性を 強調しています
科学分野:
- 心血管疾患の疫学
- 生殖内分泌学
- 公衆衛生
背景:
- 閉経はホルモンと代謝の変化を引き起こし,動脈硬化性心血管疾患 (ASCVD) のリスクを高めます.
- 年齢に関係なく,ASCVDのリスクに対する 更年期の特定の貢献は,現在進行中の調査の対象です.
- この研究は,人口をベースにした大規模なコホートの中で更年期とASCVDリスクとの関連を明らかにすることを目的とした.
研究 の 目的:
- 閉経と動脈硬化性心血管疾患 (ASCVD) のリスクとの独立した関連性を調査する.
- 更年期状態に起因するASCVDのリスクの増加を定量化するために.
- ASCVDのリスクが最も大きく影響される 更年期内の特定の年齢層を特定する.
主な方法:
- イギリスのバイオバンクで 222,007人の女性から得られたデータを分析し,心血管疾患を患っている女性を除いた.
- 高リスクは10年リスク≥7. 5%と定義され,ASCVDリスクは集団コホート式を用いて計算された.
- 年齢,社会経済,ライフスタイル,代謝,および臨床要因に調整された多変量回帰モデルが採用されました.
主要な成果:
- 閉経後の女性は,閉経前女性 (0. 81%) に比べて,ASCVDの推定リスクが著しく高かった (3. 75%).
- 高度のASCVDリスクの発生率は,閉経後の女性 (9. 65%) と閉経前の女性 (0. 41%) で大幅に高かった.
- 更年期はASCVDのリスクの0. 56%増加と,特に60歳未満の女性の高いASCVDのリスクの18%の増加と独立して関連していました.
結論:
- 閉経は,特に60歳未満の女性において,動脈硬化性心血管疾患 (ASCVD) のリスクの増加のための独立した危険因子です.
- 発見は,中年女性の心血管リスク評価に 更年期状態を組み込むことの決定的な重要性を強調しています.
- 閉経中の女性では,標的型の心血管予防策を考慮する必要があります.

Menopause
248
Menopause, a natural biological process marking the end of a woman's fertility, typically occurs between the fifth and sixth decade of life. This phase is characterized by the exhaustion of the ovarian follicle pool, leading to less responsive ovaries despite the high levels of Follicle Stimulating Hormone (FSH) and Luteinizing Hormone (LH). The consequential decrease in estrogen production results in symptoms like hot flashes, heavy sweating, headaches, hair loss, muscle pains, vaginal...

Atherosclerosis I: Introduction
76
Atherosclerosis is a progressive disorder characterized by the buildup of plaques on the arterial inner wall, causing them to narrow and harden over time. These plaques comprise lipids, calcium, blood components, carbohydrates, and fibrous tissue. The process primarily affects the intima of large and medium-sized arteries, reducing blood flow in any artery.Etiology and risk factorsThe cause of atherosclerosis is multifactorial, involving a complex interplay among endothelial injury, lipid...

Hormonal Regulation of the Menstrual Cycle
688
The ovarian cycle regulates endometrial changes throughout a single menstrual cycle via the coordinated action of gonadotrophin-releasing hormone (GnRH) and gonadotrophins.
At puberty, GnRH begins a pulsatile release pattern, which triggers the anterior pituitary gland to secrete follicle-stimulating hormone (FSH) and luteinizing hormone (LH). The frequency and amplitude of GnRH pulses vary across the menstrual cycle, with faster pulses favoring LH release and slower pulses favoring FSH...

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...

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...

Psychoneuroimmunology: Cardiovascular Disease
77
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...
