In the classical process, it was proven that ABPM data were the most significant attributes both by physician and ranking algorithms for dipper/non-dipper pattern classification as mentioned in our previous papers. To explore if any algorithm exists that would let the physician skip this diagnosis step is the main motivation of the study.
The main goal of the study is to build up a classification model that could reach a high-performance metrics by excluding ABPM data in hypertensive and non-diabetic patients.
The data used in this research have been drawn from 29 hypertensive patients without diabetes in endocrinology clinic of Marmara University in 2011. Five of 29 patient data were later removed from the dataset because of null data.
The findings showed that dipper/non-dipper pattern can be classified by artificial neural network algorithms, the highest achieved performance metrics are accuracy 87.5%, sensitivity 71%, and specificity 94%.
This novel method uses just two attributes: Ewing-score and HRREP. It offers a fast and low-cost solution when compared with the current diagnosis procedure. This attribute reduction method could be beneficial for different diseases using a big dataset.
在经典流程中,正如我们之前论文中所提到的,经证明动态血压监测(ABPM)数据是医生和排名算法用于杓型/非杓型模式分类的最重要属性。探索是否存在任何算法能让医生跳过这一诊断步骤是本研究的主要动机。
本研究的主要目标是建立一个分类模型,该模型在排除高血压且非糖尿病患者的ABPM数据的情况下仍能达到高性能指标。
本研究使用的数据取自2011年马尔马拉大学内分泌科的29例非糖尿病高血压患者。由于数据为空,29例患者数据中的5例后来从数据集中移除。
研究结果表明,杓型/非杓型模式可通过人工神经网络算法进行分类,所达到的最高性能指标为准确率87.5%、灵敏度71%和特异性94%。
这种新方法仅使用两个属性:尤因评分(Ewing-score)和心率变异性恢复周期(HRREP)。与当前诊断程序相比,它提供了一种快速且低成本的解决方案。这种属性约简方法对于使用大数据集的不同疾病可能是有益的。
