Myocardial remodelling and diastolic function in young men with arterial hypertension
Aim. To investigate the variants of left ventricular (LV) remodelling in men aged 18-25 years, with and without arterial hypertension (AH). Material and methods. In total, the study included 211 men aged 18-25 years (mean age 21,1 +/- 0,14 years), with random blood pressure (BP) elevation at previous clinical examinations. All participants underwent repeat BP measurements, 24-hour BP monitoring (BPM), echocardiography with calculation of LV myocardial mass index (LVMMI) and relative wall thickness (RWT), and evaluation of LV diastolic function (DF). Results. According to the results of clinical BP measurements and 24-hour BPM, normal BP levels were observed in 36 participants (17 %), stable AH - in 124 (58,7 %), and unstable AH - in 51(24,3 %). In patients with stable AH, LVMMI was significantly higher than in individuals with normal BP. Among participants with stable AH, 43 (34,7 %) had normal LV geometry, 75 (60,5 %) had concentric LV remodelling, and 6 (4,8 %) - concentric LV hypertrophy. Among participants with unstable All, 14 (27,5 %) had concentric LV remodelling. Comparing to normotensive individuals, patients with stable and unstable AH had lower transmitral flow ratio E/A, and significantly higher peak A velocity. Conclusion. In young 18-25-year-old men with stable AH, the typical LV remodelling variant was concentric remodelling, with a tendency towards LV diastolic dysfunction development.
