背景
- 心血管疾患 (CVD) と認知症は,特に低・中所得国 (LMICs) で,世界の主要な健康問題です.
- 血管病理は認知機能低下の要因として 認識されています
- 限定的な研究は,標準化された人口レベルのデータを用いて,CVDと認知症の間のグローバルな関連性を体系的に調査しています.
研究 の 目的
- 心血管疾患 (CVD) の発生率と認知症の発生率の間の世界的な関連性を調査する.
- 経済的地位,開発レベル,地理的地域によってこの関係を層分けする.
主な方法
- CVDと認知症の年齢標準化発生率をGlobal Burden of Disease Study 2021から利用した.
- 年齢,経済的豊かさ,遺伝的傾向,都市化の調整により,二変性および部分的相関分析を行った.
- 線形および多変量段階的回帰モデルを使用して,CVDが認知症発生率に与える影響を評価した.
主要な成果
- CVDと認知症の発生率の間に有意な全体的な関連性が見つかりました (Pearson r=0. 777,Spearman ρ=0. 868,p<0. 001).
- CVDは,混乱要因を調整した後でも,認知症発生率の差の約43. 0%を説明しました.
- 関連性はLMICと発展途上地域で強く,外周動脈疾患,心筋症,心房細動が最も強い関連性を示した.

Dementia is a collective term for cognitive disorders primarily affecting memory, thinking, and reasoning. It is not a specific disease but a syndrome, with Alzheimer's disease being the most common cause, accounting for approximately 60-80% of cases. Other types include vascular dementia, Lewy body dementia, and frontotemporal dementia. Dementia affects millions worldwide, particularly older adults, though it is not a normal part of aging.
The progression of dementia is generally gradual....
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...
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...
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...
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...
Cardiac biomarkers are enzymes, proteins, and hormones released into the blood when cardiac cells are injured. They are powerful tools for triaging.
The essential diagnostic tools for detecting myocardial necrosis and monitoring individuals suspected of having acute coronary syndrome (ACS) include:
Troponins
Troponins, particularly cardiac troponins I and T, are the most precise and sensitive markers of myocardial injury. They are detectable within 4-6 hours of myocardial injury and remain...
