Abstract:

Background

The triglyceride-glucose-BMI (TyG-BMI) index is a novel indicator reflecting insulin resistance and has been proven to be associated with hypertension. However, there is a lack of research on the relationship between the TyG-BMI index and nocturnal ambulatory blood pressure parameters as well as nocturnal hypertension.

Objective

To explore the relationship between the TyG-BMI index and nocturnal ambulatory blood pressure parameters as well as nocturnal hypertension.

Methods

A total of 396 patients with essential hypertension who underwent ambulatory blood pressure monitoring (ABPM) at the Affiliated Hospital of North China University of Science and Technology from June 2022 to October 2023 were selected as the study subjects. Patients were divided into four groups based on the quartiles of the TyG-BMI index: Q1 (n=99), Q2 (n=99), Q3 (n=99), and Q4 (n=99). Baseline data, laboratory test results, and 24-hour ABPM results were collected. The TyG-BMI index, triglyceride-glucose (TyG) index, and triglyceride/high-density lipoprotein cholesterol (TG/HDL-C) ratio were calculated. A generalized linear model was used to analyze the association between different TyG-BMI index groups and nocturnal ABPM parameters. Spearman correlation analysis was employed to assess the correlations of the TyG-BMI index, TyG index, and TG/HDL-C with nocturnal blood pressure indicators. Receiver operating characteristic (ROC) curves were plotted to analyze the predictive efficacy of the TyG-BMI index for nocturnal hypertension, and the area under the ROC curve (AUC) was calculated.

Results

There were statistically significant differences in age, BMI, TG, total cholesterol (TC), high density lipoprotein cholesterol (HDL-C), low density lipoprotein cholesterol (LDL-C), fasting blood glucose (FBG), use of renin-angiotensin-aldosterone system (RAAS) inhibitors, and proportions of stroke, diabetes, and hyperlipidemia among the Q1 to Q4 groups (P<0.05). Significant differences were also observed in 24-hour average systolic blood pressure, 24-hour average diastolic blood pressure, daytime average systolic blood pressure, daytime average diastolic blood pressure, nocturnal average systolic blood pressure, nocturnal average diastolic blood pressure, nocturnal systolic blood pressure dip, nocturnal systolic blood pressure standard deviation, and nocturnal diastolic blood pressure standard deviation among these groups (P<0.05). The results of the generalized linear model indicated that the TyG-BMI index group was a significant influencer of nocturnal average systolic blood pressure (β=6.623, P=0.002) and nocturnal average diastolic blood pressure (β=4.553, P=0.001). When stratified by the presence of hyperlipidemia or diabetes, the Q4 group was found to be a significant influencer of nocturnal average diastolic blood pressure (β=8.462, P<0.001) in subjects without hyperlipidemia or diabetes, but no correlation was observed between the TyG-BMI index group and nocturnal average systolic blood pressure (β=4.604, P=0.097) or nocturnal average diastolic blood pressure (β=1.988, P=0.285) in subjects with hyperlipidemia or diabetes. Spearman correlation analysis revealed a positive correlation between the TyG-BMI index and nocturnal average systolic blood pressure (rs=0.155, P=0.002) in hypertensive patients, and positive correlations between TG/HDL-C (rs=0.193, P<0.001), TyG index (rs=0.145, P=0.004), TyG-BMI index (rs=0.250, P<0.001) and nocturnal average diastolic blood pressure. ROC curves were plotted for TG/HDL-C, TyG index, and TyG-BMI index to predict nocturnal hypertension, with AUCs of 0.570 (95%CI=0.513-0.627, P=0.017), 0.559 (95%CI=0.502-0.616, P=0.046), and 0.618 (95%CI=0.563-0.673, P<0.001), respectively. In subjects with hyperlipidemia or diabetes, the AUCs for TG/HDL-C and TyG-BMI index predicting nocturnal hypertension were 0.578 (95%CI=0.504-0.651, P=0.043) and 0.627 (95%CI=0.557-0.698, P=0.001), respectively.

Conclusion

In patients with essential hypertension, the TyG-BMI index is positively correlated with nocturnal average diastolic blood pressure. The TyG-BMI index has a high predictive value for nocturnal hypertension.

摘要:

背景

三酰甘油葡萄糖体质量指数(TyG-BMI指数)是反映胰岛素抵抗的一种新型指标,已被证实与高血压存在关联,但目前缺乏TyG-BMI指数与夜间动态血压参数及夜间高血压的研究。

目的

探讨TyG-BMI指数与夜间动态血压参数及夜间高血压的关系。

方法

选择2022年6月—2023年10月于华北理工大学附属医院行动态血压监测(ABPM)的原发性高血压患者396例为研究对象,将患者按TyG-BMI指数四分位数分为Q1组(n=99)、Q2组(n=99)、Q3组(n=99)、Q4组(n=99)。收集患者基线资料、实验室检查结果及24 h ABPM结果。计算TyG-BMI指数、三酰甘油葡萄糖(TyG)指数、三酰甘油/高密度脂蛋白胆固醇(TG/HDL-C)。应用广义线性模型分析不同TyG-BMI指数分组与夜间ABPM参数的关联。采用Spearman相关性分析TyG-BMI指数、TyG指数、TG/HDL-C与夜间血压指标相关性。绘制受试者工作特征曲线(ROC曲线)分析TyG-BMI指数对夜间高血压的预测效能并计算ROC曲线下面积(AUC)。

结果

Q1~Q4组年龄、BMI、TG、空腹血糖(FBG)、总胆固醇(TC)、高密度脂蛋白胆固醇(HDL-C)、低密度脂蛋白胆固醇(LDL-C)、肾素-血管紧张素-醛固酮系统(RAAS)抑制剂、降脂药、脑卒中、糖尿病、高脂血症比例比较,差异有统计学意义(P<0.05)。Q1~Q4组全天平均收缩压、全天平均舒张压、日间平均收缩压、日间平均舒张压、夜间平均收缩压、夜间平均舒张压、夜间收缩压下降率、夜间收缩压标准差、夜间舒张压标准差比较,差异有统计学意义(P<0.05)。广义线性模型结果显示,TyG-BMI指数分组是夜间平均收缩压(β=6.623,P=0.002)、夜间平均舒张压(β=4.553,P=0.001)的影响因素;将研究对象按照是否患有高脂血症或糖尿病进行分层,在未患有高脂血症或糖尿病的研究对象中TyG-BMI指数Q4组是夜间平均舒张压(β=8.462,P<0.001)的影响因素;在患有高脂血症或糖尿病的研究对象中TyG-BMI指数分组与夜间平均收缩压(β=4.604,P=0.097)、夜间平均舒张压(β=1.988,P=0.285)无相关性。Spearman相关性分析结果显示,TyG-BMI指数与高血压患者的夜间平均收缩压(rs=0.155,P=0.002)呈正相关,TG/HDL-C(rs=0.193,P<0.001)、TyG指数(rs=0.145,P=0.004)、TyG-BMI指数(rs=0.250,P<0.001)与夜间平均舒张压呈正相关。绘制TG/HDL-C、TyG指数、TyG-BMI指数预测夜间高血压的ROC曲线,TG/HDL-C、TyG指数、TyG-BMI指数预测夜间高血压的AUC分别为0.570(95%CI=0.513~0.627,P=0.017)、0.559(95%CI=0.502~0.616,P=0.046)、0.618(95%CI=0.563~0.673,P<0.001);患有高脂血症或糖尿病研究对象中TG/HDL-C、TyG-BMI指数预测夜间高血压的AUC分别为0.578(95%CI=0.504~0.651,P=0.043)、0.627(95%CI=0.557~0.698,P=0.001)。

结论

原发性高血压患者中,TyG-BMI指数与夜间平均舒张压水平呈正相关。TyG-BMI指数对夜间高血压具有较高的预测价值。
