Introduction: Arterial hypertension is a frequent pathology in cardiology consultations in Chad. We report these observations with the aim of determining the prevalence of arterial hypertension in cardiological consultation at the National Reference University Hospital in N’Djamena. Methodology: We conducted an 8-month retrospective study from September 12, 2019 to April 16th, 2020, in the Cardiology Department of the National Reference Teaching Hospital. The variables studied were socio-demographic and clinical. Results: out of 352 patients seen, 121 met the selection criteria, ie a hospital prevalence of 34.34% with a female predominance. The average age was 64.5 years old with extremes ranging from 17 to 94 years old. Household were the most represented with 47.93% of cases. The most common antecedents were multiparity, arterial hypertension during pregnancy, hyperuricemia with respectively 21, 48% then 4.95% for each of the last two. The most common associated cardiovascular risk factors (FDRCV) were obesity and diabetes with 13.22% and 6.61%. Grade III systolic hypertension was the most represented with 33.05% as well as grade III diastolic hypertension with 32.23% of cases. Conclusion: Hypertension is a public health problem in Chad. Hospital prevalence has almost tripled in 26 years in the same department.
