Orthostatic hypotension and cardiovascular risk

Area of Science:

• Cardiology
• Neurology
• Geriatrics

Background:

• Orthostatic hypotension (OH) signifies cardiovascular autonomic dysfunction due to impaired autonomic nervous system control of hemodynamic homeostasis.
• OH prevalence increases with age and chronic conditions like neurodegenerative diseases, hypertension, heart failure, and diabetes.
• Over 20% of individuals aged 70+ are affected by OH, highlighting its public health significance.

Purpose of the Study:

• To underscore the critical link between orthostatic hypotension and the cardiovascular disease continuum.
• To emphasize OH as an independent predictor of adverse cardiovascular events and mortality.
• To advocate for increased clinical attention and research into effective treatments and preventive strategies for OH.

Main Methods:

• Observational analysis of existing data linking orthostatic hypotension to cardiovascular outcomes.
• Review of studies detailing the association between OH and subclinical cardiovascular changes.
• Synthesis of evidence demonstrating OH as a predictor of major adverse cardiovascular events.

Main Results:

• Orthostatic hypotension is associated with cardiac remodeling, inflammation, atherosclerosis, and thrombosis.
• OH independently predicts coronary events, stroke, atrial fibrillation, heart failure, and cardiovascular mortality.
• OH is linked to syncope, falls, and fractures, complicating cardiovascular risk management.

Conclusions:

• Orthostatic hypotension indicates disrupted circulatory homeostasis and overt autonomic dysfunction.
• OH is an underrecognized independent risk factor for mortality and cardiovascular disease.
• Further research is crucial for developing effective treatments and preventive measures for OH.
