Abstract
Objective: Early onset of untreated arterial hypertension is associated with an increased risk for cardiovascular (CV) diseases. The evaluation of hypertension-mediated organ damage (HMOD) helps estimating CV risk. We investigated the incidence of HMOD in young first, diagnosed and nevertreated patients with systolic arterial hypertension (SH) to identify high CV-risk patients based on the presence of HMOD.
Methods: CV risk factors [smoking, obesity (body mass index, BMI)], hyperlipidemia and 5 HMODs [arterial stiffness (pulse wave velocity, PWV), left ventricular diastolic dysfunction [(DD (E/Ea)], cardiac hypertrophy (left ventricular mass index, LVMI), coronary artery microcirculation (CFR), and carotid intima-media thickness (cIMT)] were evaluated before treatment initiation in 220 patients, aged ≤50 years [median (interquartile range, IQR) age=43(38-47)], with SH diagnosed by ambulatory blood pressure monitoring (24-h ABPM).
Results: Smoking (40%) and obesity [median (IQR) BMI=30(26-32) kg/m2](40%) were found in young hypertensives. HMOD was found in 50% of hypertensives (10% had ≥2 HMOD). The most prevalent HMODs were increased by cIMT (32%) and PWV (19%), LVH (9%), impaired CFR (6%) and DD (1%). Only PWV (beta=0.27, p<0.001) and LVMI (beta=0.41, p<0.001) were associated with systolic BP burden. In a subgroup analysis, patients with ≥2 HMOD were older with increased office BP and 24- h ABPM, impaired lipid profile, and increased LVMI, PWV, CFR, and cIMT compared with the rest of the hypertensives.
Conclusion: The presence of ≥2 of the studied HMOD (PWV, LVMI, cIMT, E/Ea, CFR) in young hypertensives characterizes a “high-risk population”. Arterial stiffness represents the predominant HMOD and in the whole population and "high-risk population".
