Dialysis-Induced Cardiovascular and Multiorgan Morbidity

Area of Science:

• Nephrology
• Cardiology
• Internal Medicine

Background:

• Hemodialysis, while life-saving, is associated with significant mortality and morbidity.
• Patient-hemodialysis interactions can induce systemic circulatory stress, exacerbating comorbidities and causing end-organ damage.

Purpose of the Study:

• To review the adverse systemic effects of intermittent hemodialysis.
• To summarize pathophysiologic consequences and evidence for cardioprotective interventions.
• To explore novel approaches for reducing hemodialysis-related systemic burden.

Main Methods:

• Review of intradialytic imaging (echocardiography, MRI) and cardiac biomarker kinetics (Troponin I).
• Identification of factors contributing to systemic circulatory stress during hemodialysis.
• Analysis of existing and emerging interventions for hemodialysis optimization.

Main Results:

• Hemodialysis-induced factors like hypovolemia, hypotension, hypoxemia, and electrolyte shifts contribute to systemic stress.
• This stress negatively impacts cognitive function, symptom burden, and quality of life.
• Intradialytic imaging and biomarkers confirm end-organ damage.

Conclusions:

• Current intermittent hemodialysis poses risks beyond patient comorbidities.
• Cardioprotective strategies and technological advancements are crucial for mitigating adverse effects.
• Personalized medicine approaches hold promise for improving hemodialysis outcomes.
