Cardiac Remodeling in Structure and Function Six Months After Kidney Transplantation

Area of Science:

• Nephrology
• Cardiology
• Transplantation Medicine

Background:

• Cardiovascular disease is a major cause of mortality in chronic kidney disease (CKD) patients.
• Suboptimal dialysis in Mexico due to economic constraints exacerbates cardiac damage, impacting kidney transplant prognosis.
• Pre-transplant cardiac status is often poorer in Mexican CKD patients compared to international cohorts.

Purpose of the Study:

• To quantify the improvement in echocardiographic parameters six months after renal transplantation.
• To assess the impact of renal transplantation on cardiovascular function in CKD patients.
• To demonstrate the benefits of renal transplantation on cardiac health in a resource-limited setting.

Main Methods:

• An observational, analytic, prospective study.
• Involved 23 CKD patients who underwent renal transplantation in 2016.
• Assessed patients at 6 months post-transplant with a glomerular filtration rate ≥80 mL/min (CKD-EPI).

Main Results:

• Left ventricular ejection fraction increased from 57.17% to 64.09%.
• Right ventricular ejection fraction increased from 0.56 to 0.60.
• Pulmonary arterial systolic pressure decreased from 44.57 to 39.74 mm Hg.
• Significant reductions observed in mitral, tricuspid, pulmonary, and aortic insufficiency (P < .05).

Conclusions:

• Renal transplantation leads to significant cardiovascular improvements in CKD patients.
• Echocardiographic parameters show marked enhancement six months post-transplant.
• These findings highlight the cardiovascular benefits of renal transplantation, even in populations with pre-existing cardiac compromise.
