Beyond the sphygmomanometric numbers: hypertension as a syndrome

Area of Science:

• Cardiovascular Medicine
• Hypertension Research
• Endothelial Function Studies

Background:

• Hypertension is a complex syndrome linked to multiple risk factors including hypercholesterolemia, left ventricular hypertrophy, insulin resistance, and vascular dysfunction.
• These risk factors often precede the development of elevated blood pressure (BP), even in normotensive individuals with a family history of hypertension.
• Endothelial dysfunction, characterized by an imbalance between angiotensin II and nitric oxide, is a common underlying factor in these interrelated conditions.

Purpose of the Study:

• To highlight the unifying role of endothelial dysfunction in the complex syndrome of hypertension.
• To emphasize the clinical implications of recognizing endothelial dysfunction for early disease detection and management.
• To advocate for the incorporation of specific therapeutic strategies targeting endothelial function in clinical practice.

Main Methods:

• Review of existing scientific literature on hypertension and its associated risk factors.
• Analysis of the common pathways linking various risk factors to the development of hypertension.
• Focus on the role of endothelial cell signaling, specifically the angiotensin II and nitric oxide balance.

Main Results:

• Endothelial dysfunction is identified as a central mechanism connecting diverse hypertension-associated risk factors.
• The imbalance in endothelial cell function can manifest before overt hypertension is diagnosed.
• This understanding supports the concept of a broader 'hypertension syndrome' beyond just elevated BP.

Conclusions:

• Early identification of patients exhibiting signs of the hypertension syndrome is crucial.
• Intervention strategies should aim to prevent disease onset or progression by addressing underlying endothelial dysfunction.
• Angiotensin converting enzyme (ACE) inhibitors are proposed as a therapeutic option to restore endothelial balance and manage the hypertension syndrome.
