- ウイルス学
- 生物化学
背景:
- 深刻な急性呼吸器症候群の新型コロナウイルス2型 (SARS-CoV-2型) は,心血管の健康に影響を与えるCOVID-19を引き起こす.
- 心血管疾患 (CVD) と関連した内皮機能不全 (ED) は,COVID-19の病原性において重要な役割を果たします.
- COVID-19に関連したEDは,低高密度脂質 (HDL) が疾患の重症性に相関する脂質代謝の調節不良から生じる可能性があります.
研究 の 目的:
- 炎症性脱脂症を標的とした治療がCOVID-19患者にとって有益であると仮定する.
- 脂質代謝,内皮機能不全,およびCOVID-19の合併症との関係を調べる.

主要な成果:
- 内皮のACE2発現は,COVID-19における心血管症状を説明する可能性がある.
- HDLの抗酸化能力の低下は,酸化LDL (oxLDL) とMox-LDLの生成につながる可能性があります.
- Mox- LDLは抗繊維分解活性を示し,拡散性血管内凝固および不全性脳卒中のリスクを増加させる可能性があります.
結論:
- 炎症性脱脂症は,COVID-19の病原性における重要な要因である.
- 炎症性脱脂症を標的とした治療は,COVID-19の有望な治療戦略です.

Coronary Artery Disease I: Introduction

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...

Coronary Artery Disease II: Pathophysiology
34
Coronary Artery Disease (CAD) originates from a series of events that impair the function of coronary arteries, the blood vessels responsible for delivering oxygen-rich blood to the heart muscle. The pathophysiology of CAD is closely linked to atherosclerosis, a chronic inflammatory and lipid-driven condition affecting the vascular endothelium.1. Endothelial DamageThe process begins with damage to the vascular endothelium, which serves as a protective barrier between the blood and the vessel...

Psychoneuroimmunology: Cardiovascular Disease
78
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 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...

Atherosclerosis I: Introduction
77
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...

Atherosclerosis III: Management
33
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...
