We analyzed in NYHA I hypertensives the interactions between Carotid Intima-Media Thickness (IMT), Hypertension and Cardiovascular (CV) risk factors and relationships between IMT, CV risk factors and left ventricular (LV) geometric remodelling. 198 asymptomatic, never treated, essential hypertensives (age: 58.2 +/- 13) and 67 (age-gender matched) healthy subjects, were studied. Complete clinical examination, 2D Doppler echocardiography and vascular echography were performed in all study subjects. Major values of IMT are present in concentric LVH. Distribution of IMT among risk factors groups shows an higher IMT respect to increasing number of risk factors (P < 0.001). Significant correlation are present between pulse pressure and IMT (P < 0.006; r = 0.19) and IMT and LVM (P < 0.0001; r = 0.35). Altered patterns of LV geometry and carotid structural changes occur in many patients with essential hypertension. LVH or carotid remodeling are greater in elderly, in patients with higher systolic BP and with associated CV risk factors.
我们分析了纽约心脏协会(NYHA)I 级高血压患者颈动脉内膜中层厚度(IMT)、高血压与心血管(CV)危险因素之间的相互作用,以及 IMT、CV 危险因素与左心室(LV)几何重构之间的关系。研究纳入了 198 例无症状、未经治疗的原发性高血压患者(年龄:58.2±13 岁)和 67 例(年龄和性别匹配)健康对照者。所有研究对象均接受了完整的临床检查、二维多普勒超声心动图和血管超声检查。LVH 患者的 IMT 主要值更高。颈动脉 IMT 在危险因素组中的分布显示,随着危险因素数量的增加,IMT 也随之增加(P<0.001)。脉压与 IMT 之间存在显著相关性(P<0.006;r=0.19),IMT 与 LVM 之间也存在显著相关性(P<0.0001;r=0.35)。许多原发性高血压患者会出现 LV 几何结构改变和颈动脉结构变化。颈动脉重塑和 LVH 在老年患者、收缩压较高的患者以及伴有 CV 危险因素的患者中更为严重。
