Reversible cardiomyopathies--a review

Area of Science:

• Cardiology
• Nephrology
• Hepatology
• Metabolic Surgery

Background:

• End-stage renal disease, cirrhosis, obesity, tachycardia, and extreme stress can impair left ventricular function.
• These conditions are associated with specific cardiomyopathies.
• Emerging evidence suggests these cardiomyopathies may be reversible.

Purpose of the Study:

• To review current data on the reversibility of cardiomyopathies linked to specific underlying conditions.
• To highlight the impact of interventions on cardiac function in these patient groups.

Main Methods:

• Literature review of studies investigating cardiomyopathy reversal.
• Analysis of outcomes following renal transplantation, liver transplantation, bariatric surgery, and treatments for tachycardia and stress-induced conditions.

Main Results:

• Renal transplantation can reverse uremic cardiomyopathy.
• Liver transplantation is associated with reversal of cirrhotic cardiomyopathy.
• Bariatric surgery can resolve obesity cardiomyopathy.
• Tachycardia-induced cardiomyopathy is reversible with rate/rhythm control.
• Stress-induced cardiomyopathy can improve with supportive care.

Conclusions:

• Cardiomyopathies associated with end-stage renal disease, cirrhosis, obesity, tachycardia, and stress are often reversible.
• Addressing the underlying condition is key to restoring left ventricular function.
