| Sumario: | Introduction: Hypertension targets many organs. This study investigates left ventricular hypertrophy (LVH), which can lead to conduction disorders, arrhythmias, and heart failure. Endothelial dysfunction (ED) was assessed using serum asymmetric dimethyl-arginine (ADMA) levels. Methods: The study included a total of 90 voluntary participants: 30 patients with hypertension and left ventricular hypertrophy, 30 hypertensive patients without hypertrophy, and 30 normotensive healthy controls. Serum ADMA levels were used to detect endothelial dysfunction. Results: The results showed that serum ADMA levels were significantly higher in the patient group compared to the control group. However, there was no significant difference in serum ADMA levels between the two subgroups of patients, with or without left ventricular hypertrophy (LVH). A correlation analysis was performed, revealing no correlation between serum ADMA levels and the left ventricular mass index (LVMI). Discussion and Conclusion: There appears to be no direct relationship between LVH and endothelial dysfunction. Furthermore, inflammatory processes seem to contribute to the development of LVH rather than endothelial dysfunction. The duration of exposure to high blood pressure and the stage of hypertension are also believed to impact this process.
