It has been previously documented that carotid intima-media thickness (cIMT) is a predictor of cardiovascular disease. The aim of this study was to identify clinical parameters associated with an increased cIMT treated hypertensive women. Female patients (n = 116) with essential hypertension, aged 40-65 years, were included in this study. Vascular ultrasound was performed and the patients were divided into two groups according to the values of cIMT (< or ≥0.9 mm). Patients with greater cIMT presented significantly higher systolic blood pressure and pulse pressure. Serum HDL-cholesterol was significantly lower and CRP was significantly higher in the same group. There was a significant correlation between cIMT and age (r = 0.25, P = 0.007), systolic blood pressure (r = 0.19, P = 0.009), pulse pressure (r = 0.30, P = 0.001), and LDL-cholesterol (r = 0.19, P = 0.043). cIMT was correlated to CRP (r = 0.31, P = 0.007) and negatively correlated to HDL-cholesterol (r = 0.33, P = 0.001). In logistic regression, only HDL-cholesterol, CRP, and pulse pressure were shown to be independent variables associated to increased cIMT. In conclusion, pulse pressure, HDL-cholesterol, and CRP are variables correlated with cIMT in treated hypertensive women.
此前已有文献记载,颈动脉内膜中层厚度(cIMT)是心血管疾病的一个预测指标。本研究的目的是确定与接受治疗的高血压女性cIMT增加相关的临床参数。本研究纳入了年龄在40 - 65岁之间的116例原发性高血压女性患者。进行了血管超声检查,并根据cIMT值(<或≥0.9毫米)将患者分为两组。cIMT较高的患者收缩压和脉压显著更高。同一组患者的血清高密度脂蛋白胆固醇显著更低,而C反应蛋白显著更高。cIMT与年龄(r = 0.25,P = 0.007)、收缩压(r = 0.19,P = 0.009)、脉压(r = 0.30,P = 0.001)和低密度脂蛋白胆固醇(r = 0.19,P = 0.043)之间存在显著相关性。cIMT与C反应蛋白相关(r = 0.31,P = 0.007),与高密度脂蛋白胆固醇呈负相关(r = 0.33,P = 0.001)。在逻辑回归分析中,只有高密度脂蛋白胆固醇、C反应蛋白和脉压被证明是与cIMT增加相关的独立变量。总之,脉压、高密度脂蛋白胆固醇和C反应蛋白是与接受治疗的高血压女性cIMT相关的变量。
