Introduction:

High blood pressure is the main risk factor for the development of cardiovascular diseases. Its detection in young adults makes necessary to look for a secondary and potentially correctable cause. Objective: To determine the clinical characteristics of arterial hypertension in adults under 30 years of age who attended the Hospital Nacional of Itauguá, Paraguay, in the period 2019-2021.

Subjects and methods:

Retrospective observational cross-sectional descriptive study which included 50 patients between 18 and 30 years of age with arterial hypertension. The research was approved by the Ethics Committee of the National University of Itapúa, Paraguay. Results: The mean age was 23±4 years, most patients were from urban areas, 58% was male and had a low educational level. The mean body mass index was 23.5±5 k/m2 and 58% had no family history of arterial hypertension. The mean blood pressure values were 150 mmHg for systolic and 100 mmHg for diastolic. Secondary arterial hypertension was detected in 86% of the sample. The most frequent etiology was parenchymal kidney disease (86%), of which 89% had chronic kidney disease and lupus nephritis. The frequency of target organ damage was 86%, the eye fundus was abnormal in 8%, 46% had left ventricular hypertrophy by electrocardiogram and 58% by echocardiogram, 78% had abnormal renal architecture by ultrasound, 57% had elevated creatininemia, 76% trace protein in randomly collected urine, and 80% elevated 24-hour proteinuria. Conclusion: The prevalent form of arterial hypertension in the young adults studied was secondary, with a slight predominance of males, with normal weight and without family history. The main cause was renal parenchymal disease. More than half of the cases presented left ventricular hypertrophy and high proteinuria.
