Insights
Chronic fluid overload significantly impacts hemodialysis patients, leading to severe congestive cardiomyopathy. Aggressive ultrafiltration effectively reversed cardiac abnormalities, highlighting the importance of fluid management in dialysis.
Area of Science:
- Nephrology
- Cardiology
Background:
- Hemodialysis patients can develop severe cardiac complications.
- Chronic fluid overload is a known but often neglected issue in dialysis.
Observation:
- A patient on hemodialysis presented with severe congestive cardiomyopathy, including chamber dilation, reduced ejection fraction, and valve regurgitation.
- Ascites and hypotension were also present.
Findings:
- Complete resolution of all cardiac abnormalities and related symptoms occurred within 5 months.
- This reversal was achieved through persistent ultrafiltration during or between dialysis sessions.
Implications:
- Chronic fluid overload is a primary contributor to cardiac disease in hemodialysis patients.
- Prioritizing prevention and management of hidden fluid overload is crucial for improving outcomes in this population.
Abstract:
A patient is presented who after 2 years of hemodialysis showed all of the features of congestive cardiomyopathy to a very severe degree: dilation of all cardiac compartments, increased left ventricular mass, low ejection fraction, diastolic disturbances, third- to fourth-degree mitral and tricuspid regurgitation, ascites, and low blood pressure. All of these abnormalities gradually but completely disappeared during 5 months of persistent ultrafiltration during or between dialysis sessions. It was concluded that chronic fluid overload was a major factor in the cardiac disease of this patient. Unrecognized hidden fluid overload has long been known (but also neglected), and its prevention deserves top priority in chronic dialysis patients.

Acute kidney injury develops suddenly and can be caused by pre-renal causes (e.g., hypovolemia, shock), intrinsic renal causes (e.g., acute tubular necrosis), or post-renal causes (e.g., urinary obstruction). In contrast, chronic renal failure progresses gradually over time and is often...
