Epidemiological, Clinical and Echocardiographic Aspects of Non-Obstructive Hypertrophic Cardiomyopathy in the Nephrology and Haemodialysis Department of the Point G University Hospital

Abstract

Introduction: LVH is the earliest cardiovascular abnormality in CKD. It is a significant risk factor for mortality and cardiovascular morbidity in patients with chronic kidney disease. The objective of this study was to investigate non-obstructive hypertrophic cardiomyopathy in CKD patients hospitalised in the nephrology and haemodialysis department of the Point G University Hospital. Methods: This is a prospective study carried out from January 1, 2021 to December 31, 2021 and concerned chronic renal failure patients with non-obstructive hypertrophic cardiomyopathy. Results: During our study, we recorded 89 cases of non-obstructive hypertrophic cardiomyopathy, a prevalence of 42.8%. The sex ratio was 1.2 in favour of men. The average age of the patients was 45 ± 14.4 years with extremes of 16 and 78 years. The risk factors frequently found were anaemia (100%) and hypertension (92.1%). The clinical picture was dominated by the left heart failure syndrome (66.3% of cases). The different types of echocardiographic hypertrophy found were concentric (72%), eccentric (18%) and septal hypertrophy (10%). Conclusion: Non-obstructive hypertrophic cardiomyopathy is the early cardiovascular abnormality encountered in CKD. It is associated with cardiovascular risk factors such as hypertension, anaemia and phosphocalcic disorders.
