Hypertrophic Cardiomyopathy and Chronic Kidney Disease: An Updated Review

The links between chronic kidney disease (CKD) and cardiac conditions such as coronary heart disease or valvular disease are well established in the literature. However, the relationship between hypertrophic cardiomyopathy (HCM) and CKD is not as frequently described or researched. HCM is the most common form of inherited cardiac disease. It is mainly transmitted in an autosomal dominant fashion and caused by mutations in genes encoding sarcomere proteins. HCM is estimated to affect 0.2% of the general population and has an annual mortality rate of between approximately 0.5 and 1%. Our review article aims to summarize the genetics of HCM; discuss the potential clinical mimics that occur concurrently with HCM and CKD, potential interlinks that associate between these two conditions, the role of renal dysfunction as a poor prognostic indicator in HCM; and based on currently available evidence, recommend a management approach that may be suitable when clinicians are faced with this clinical scenario.
