[Energy-dependent pathogenesis in chronic hypertension]

Area of Science:

• Cardiovascular Research
• Mitochondrial Biology
• Hypertension Pathophysiology

Context:

• Arterial hypertension is a complex condition with multifactorial origins.
• Mitochondrial dysfunction and cellular energy deficits are increasingly recognized as contributing factors.
• Existing research often focuses on systemic factors, with less emphasis on cellular energy metabolism.

Purpose:

• To present a novel perspective on arterial hypertension, linking it directly to cellular energy deficiency.
• To elucidate the role of mitochondrial dysfunction, specifically impaired ATP production, in the pathogenesis of hypertension.
• To explore the compensatory mechanisms and the progression of hypertension towards irreversibility.

Summary:

• Stable increase in systemic blood pressure (BP) is causally linked to cellular and tissue energy deficiency.
• Mitochondrial dysfunction, characterized by impaired energy conversion and decreased ATP production, underlies this energy deficit.
• In primary hypertension, mitochondrial calcium overload is implicated, while secondary hypertension may involve uncoupling agents triggering mitochondrial dysfunction.
• Hypertension initiation involves sympathetic nervous system activation, with elevated BP acting as a compensatory mechanism for ATP deficiency.
• Kidney involvement, vascular remodeling, and sclerotic changes contribute to BP stabilization and the development of irreversible hypertension.

Impact:

• This review offers a new paradigm for understanding hypertension, focusing on cellular bioenergetics.
• Highlights the critical role of mitochondria in hypertension, potentially opening new therapeutic targets.
• Provides insights into the transition of hypertension from a compensatory state to an irreversible condition.
