Hypertension: where have we gone wrong and how can we fix it?

Area of Science:

• Cardiology
• Genetics
• Internal Medicine

Background:

• Hypertension is traditionally defined by elevated blood pressure, with treatment goals focused on normalization.
• Despite effective blood pressure control, expected reductions in coronary artery disease (CAD) incidence have not been achieved.
• This discrepancy necessitates a re-evaluation of hypertension's role in CAD development.

Purpose of the Study:

• To investigate if hypertension encompasses more than elevated blood pressure.
• To explore the concept of hypertension as a complex inherited syndrome of cardiovascular risk factors.
• To understand the implications for diagnosing and managing hypertension.

Main Methods:

• Review of existing research and clinical findings on hypertension and coronary artery disease.
• Analysis of the components of the 'hypertension syndrome'.
• Comparison of 'number-based' versus 'syndrome-based' management approaches.

Main Results:

• Hypertension is increasingly recognized as a syndrome, not just high blood pressure.
• Associated risk factors include lipid abnormalities, insulin resistance, renal and endocrine changes, obesity, coagulation disorders, left ventricular hypertrophy, and vascular dysfunction.
• Elevated blood pressure may be a late manifestation of this underlying syndrome.

Conclusions:

• Effective hypertension management requires viewing it as a complex syndrome with multiple contributing factors.
• Early diagnosis and treatment targeting the entire syndrome, not just blood pressure numbers, are essential.
• This paradigm shift may improve outcomes in patients with hypertension and reduce coronary artery disease incidence.
