Few studies have been conducted on hypertension among youth in Mali?hence the interest of our study aimed to clarify certain aspects what are not taken account yet in previous studies.?Objective: Determine the clinical and para-clinical characteristics of hypertension among 18 to 35 years old young people.?Methods:?This cross-sectional and retrospective study of 24 months from January 1st, 2009 to December 31st, 2010?in the cardiology department of the Gabriel Touré UTH.?Results:?We identified 132 cases during the study period out of 2146 cases of hypertension with a prevalence of 6.1%. The female gender represented 81.8%, with a sex ratio of 45.59, 1% of patients had an unknown family history of hypertension. The age group of 31 to 35 years accounted for 43.9%. The circumstances of discovery were dominated by exertional dyspnea (37.9%). Body mass index was normal in 45.5% of patients. The higher BMI was more common in female patients with 39.39% (p?= 0.045). In the sample,53% of patients had a systolic blood pressure between 140?and 159 mmHg and 38.6% had diastolic blood pressure ≥ 110 mmHg with no significant difference (p?> 0.5). The high creatinine level was found in 18.18% of our patients. The ECG?found?84.6%?of left ventricular hypertrophy among cavitary hypertrophies. The echocardiography has found cavitary?dilatation in 40.04% of cases;it concerned the left ventricle in 25.71%. Also 18.57% of our patients had impaired left ventricular systolic function. Among the complications found in our patients, kidney failure led with 56%.?Conclusion:?Hypertension is not a rare event among young population even with a normal body mass index. It is often discovered during complications that can be dreadful.
