Recent advances in the pathophysiology of hypertension

Area of Science:

• Cardiovascular Science
• Molecular Medicine
• Pathophysiology

Background:

• Hypertension is a leading global cause of morbidity and mortality.
• It is a major modifiable risk factor for heart disease, stroke, and kidney disease.
• While 5% of cases are secondary hypertension, 95% are primary hypertension with unknown etiology.

Purpose of the Study:

• To highlight novel concepts in the molecular mechanisms of hypertension.
• To explore new pathophysiological processes underlying hypertension.

Main Methods:

• Review of current scientific literature on hypertension.
• Focus on molecular-level insights including oxidative stress, mitochondrial dysfunction, inflammation, epigenetics, and non-coding RNAs.
• Inclusion of newly discovered components of the renin-angiotensin system, such as alamandine.

Main Results:

• Growing evidence points to oxidative stress, mitochondrial dysfunction, inflammation, epigenetics, and non-coding RNAs in hypertension.
• New components of the renin-angiotensin system, like alamandine, are implicated in hypertension development.
• Multiple factors including genetics, environment, hemodynamics, and physiological systems contribute to hypertension.

Conclusions:

• Hypertension is a multifactorial disorder with complex molecular underpinnings.
• Emerging molecular mechanisms offer new avenues for understanding and potentially treating hypertension.
• Further research into these novel pathways is crucial for advancing cardiovascular health.
