Description
Introduction:
A well-established link exists between cardiovascular disease (CVD) and chronic kidney disease (CKD). Reduced kidney function triggers a cascade of hemodynamic changes, including systemic hypertension and inflammatory responses, leading to left ventricular hypertrophy (LVH). In advanced stages of CKD, uremic cardiomyopathy (UC) is implicated in the progression of CKD and LVH. While the progression of CKD to LVH has been investigated, there remains a gap in the literature regarding the mechanisms underlying the preservation of left ventricular architecture and function in the pathogenesis of CKD. This study presents a post-mortem histological analysis of an 82-year-old African American male cadaver to examine the preservation of the structural integrity of the left ventricle in advanced CKD.
Methods:
Histological analysis was performed on an 82-year-old male cadaver with advanced CKD and a documented cause of death of cardiopulmonary arrest and senile brain degeneration. Gross examination of the kidneys was performed before tissue sampling. Samples were obtained from five sites: the left ventricle, superior renal cyst, inferior kidney, kidney lobule, and kidney cyst fluid. Samples were stained with hematoxylin and eosin (H&E), and histological evaluation was performed at 10x and 20x magnification by a pathologist.
Results:
Gross examination of the kidneys revealed irregular surfaces with cystic changes and loss of the normal corticomedullary boundary, consistent with CKD. The superior renal cyst showed a cystic space within the renal parenchyma, surrounded by tubular atrophy and interstitial inflammatory infiltrates. The inferior kidney showed glomerular atrophy characterized by a shrunken glomerular tuft with widened Bowman’s space and surrounding renal tubular atrophy. The kidney lobule showed glomerular atrophy with widened Bowman’s space and surrounding interstitial edema and inflammatory infiltrates, indicating both chronic and active injury, and the analysis of cyst fluid showed bloody exudate. In contrast, the left ventricle specimen showed muscle bundles separated by a delicate connective tissue stroma containing capillaries and small blood vessels, with no evidence of hypertrophy, degeneration, or an inflammatory infiltrate, indicating a normal left ventricle.
Discussion:
The significance of the histological analysis lies in the marked absence of LVH and myocardial fibrosis despite clear histological evidence of CKD. CKD is commonly associated with cardiac remodeling, including LVH and myocardial fibrosis, which were not observed in this case. This preservation of myocardial structure may suggest the presence of protective factors that mitigated cardiac remodeling, such as pharmacological intervention. Due to the absence of a documented medical history, it is not possible to determine if the individual was receiving antihypertensive therapy. The cause of death, cardiopulmonary arrest, represents a nonspecific terminal event rather than a definitive etiology. Therefore, the absence of structural cardiac abnormalities suggests that the underlying cause of death cannot be determined from cardiac histology alone. Given the patient’s age and race, which are associated with higher rates of LVH and cardiac remodeling in CKD, the preservation of normal myocardial architecture is notable. This case highlights the variability in cardiac involvement among patients with CKD, suggesting that additional factors may influence whether cardiac remodeling develops despite advanced renal disease.
