Cardiovascular Outcomes in Kidney Transplantation
Summary
Cardiovascular disease remains the leading cause of mortality in recipients of kidney transplants, reflecting the complex interplay between uraemic cardiomyopathy, hypertension, and metabolic disturbances. End-stage renal disease induces structural and functional alterations in the myocardium, notably left ventricular hypertrophy, impaired diastolic relaxation and subclinical systolic dysfunction. Successful transplantation alleviates uraemia, often leading to regression of left ventricular mass and improvement in strain metrics, yet residual diastolic dysfunction and persistent arterial stiffness may endure. Graft function exerts a direct influence on cardiovascular status: suboptimal renal output correlates with sustained cardiac remodelling and higher pulmonary pressures. Contemporary practice therefore emphasises longitudinal cardiac monitoring, rigorous blood pressure and anaemia control, and early detection of graft dysfunction to mitigate long-term cardiovascular risk. Emerging imaging techniques have refined detection of subtle myocardial changes, while systematic appraisals of left atrial and ventricular deformation underscore the heterogeneity of recovery. Understanding these dynamics is critical to individualise post-transplant care and to develop targeted interventions that preserve both graft and cardiac health.

Cardiovascular Outcomes in Kidney Transplantation publication trend
The graph below shows the total number of articles in cardiovascular outcomes in kidney transplantation across all publications each year (not limited to Nature Index journals).
Technical terms
Left ventricular hypertrophy: Thickening of the ventricular wall typically resulting from chronic pressure overload and uraemic toxin exposure.
Global longitudinal strain: A measure of myocardial deformation reflecting subclinical systolic function, assessed by speckle tracking.
Diastolic dysfunction: Impairment of ventricular relaxation or filling, often manifesting as elevated filling pressures.
Speckle tracking echocardiography: An imaging technique that quantifies myocardial strain based on tracking natural acoustic markers.
Graft function: The ability of the transplanted kidney to achieve adequate filtration, often estimated by glomerular filtration rate.
