Endothelial Dysfunction as the Common Pathway Linking Obesity, Hypertension and Atherosclerosis

Area of Science:

• Cardiovascular Science
• Endothelial Biology
• Metabolic Syndrome Research

Background:

• Endothelial dysfunction is central to cardiovascular disease pathogenesis.
• It involves oxidative stress, metabolic imbalances, and adipokine dysregulation.
• Key factors include reduced nitric oxide bioavailability and vascular inflammation.

Purpose of the Study:

• To elucidate the complex mechanisms underlying endothelial dysfunction.
• To highlight the roles of oxidative stress, adipokines, dyslipidemia, hypertension, and obesity.
• To emphasize the need for targeted interventions for cardiometabolic risk reduction.

Main Methods:

• Review of current literature on endothelial dysfunction.
• Analysis of the interplay between oxidative stress, metabolic factors, and vascular health.
• Examination of the roles of specific hormones and lipids.

Main Results:

• Excessive reactive oxygen species impair nitric oxide synthase, reducing nitric oxide bioavailability.
• Adipokines (leptin, adiponectin, resistin) differentially affect vascular homeostasis.
• Dyslipidemia (oxidized LDL), hypertension, and obesity exacerbate endothelial injury and inflammation.

Conclusions:

• Interrelated mechanisms involving oxidative stress and metabolic dysregulation drive endothelial dysfunction.
• These processes contribute to atherosclerosis and diabetic vascular complications.
• Further research is needed to develop targeted therapies for endothelial health restoration.
