与北斗星HT相比,非北斗星高血压(HT)具有更大的风险。生长分化因子15(GDF-15)最近成为心血管疾病的一个新的和独立的标志物。在诊断和预后方面。我们的目的是评估新诊断的无左心室肥厚的HT患者的昼夜节律血压(BP)模式与血清GDF-15水平的关系。
根据24小时动态血压监测(ABPM)选择新诊断的非北斗型(n=66)和北斗型(n=60)HT患者。对照包括健康的血压正常的受试者(n=31)。数据是通过体检收集的,实验室分析,ABPM,还有超声心动图.使用ELISA测量GDF-15。
与对照组和对照组相比,非浸渍者中的GDF-15水平更高(557.53±91.7、513.79±62.86和494.44±79.30ng/L,分别,p<0.001)。在双变量线性相关分析中,GDF-15与肾小球滤过率呈正相关(r=0.180,p=0.030),总胆固醇(r=0.170,p=0.038),间隔E/E比(r=0.344,p=0.001),侧向E/E比(r=0.366,p<0.001),夜间收缩压(r=0.166,p=0.046),和夜间舒张压血压(r=0.188,p=0.024);然而,它与间隔和横向E'速度呈负相关(分别为r=0.268,p=0.005和r=0.236,p=0.013)。此外,GDF-15水平和夜间舒张压仍与非北斗星HT独立相关。在ROC分析中,GDF-15的最佳临界值为524.6ng/L,敏感性为56.7%,特异性为72.4%(AUC:0.676,95%CI:0.580-0.772,p<0.05)。
我们的结果显示GDF-15在非北斗型HT组中上调。GDF-15和夜间舒张压血压与非浸渍模式独立相关。这项研究可能表明GDF-15可能用于预测非铲斗HT。
Non-dipper hypertension (HT) confers greater risk compared with dipper HT. Growth differentiation factor 15 (GDF-15) recently emerged as a novel and independent marker of cardiovascular disease, both in diagnostic and prognostic scopes. Our aim was to evaluate the relationship of circadian blood pressure (BP) pattern with serum GDF-15 level in newly diagnosed HT patients without left ventricular hypertrophy.
Newly diagnosed non-dipper (n = 66) and dipper (n = 60) HT patients were selected according to 24-h ambulatory BP monitoring (ABPM). The controls comprised healthy normotensive subjects (n = 31). Data was collected through physical examination, laboratory analysis, ABPM, and echocardiography. GDF-15 was measured using ELISA.
Greater GDF-15 level was found in the non-dippers compared with the dippers and the controls (557.53 ± 91.7, 513.79 ± 62.86, and 494.44 ± 79.30 ng/L, respectively, p < 0.001). In bivariate linear correlation analysis, GDF-15 correlated positively with glomerular filtration rate (r = 0.180, p =0.030), total cholesterol (r = 0.170, p = 0.038), septal E/E\' ratio (r = 0.344, p = 0.001), lateral E/E\' ratio (r = 0.366, p < 0.001), nighttime systolic BP (r = 0.166, p = 0.046), and nighttime diastolic BP (r = 0.188, p = 0.024); however, it correlated negatively with septal and lateral E\' velocities (r = 0.268, p = 0.005 and r = 0.236, p = 0.013, respectively). Furthermore, GDF-15 level and nighttime diastolic BP remained independently associated with non-dipper HT. In ROC analysis, optimal cutoff value for GDF-15 was 524.6 ng/L with 56.7% sensitivity and 72.4% specificity (AUC: 0.676, 95% CI: 0.580-0.772, p < 0.05).
Our results showed GDF-15 upregulation in the non-dipper HT group. GDF-15 and nighttime diastolic BP were independently associated with the non-dipping pattern. This study may suggest possible utilization of GDF-15 in the prediction of non-dipper HT.
