#earch, there is no available papers found
that relates PPG with UA level even though PPG is highly associated with vessel condition.
The five phases in this research are data collection, signal preprocessing
including denoising and signal quality indexes, features extraction
for PPG and SDPPG waveform, statistical analysis for feature selection and
classification of UA levels usingML. Adding PPG to the current arteriograph
able to reduce cost and increase the prediction performance.
PPG and arteriograph data were measured from 113 subjects, and
226 sets of data were collected from the left and right hands of the subjects.
The performance of four types of ML, namely, artificial neural network (ANN),
linear discriminant analysis (LDA), k-nearest neighbor (kNN), and
support vector machine (SVM) in predicting hyperuricemia was compared.
From the total of 98 features extracted, 16 features of which showed
statistical significance for hyper and normouricemia.
ANN gives the best performance compared to the other three ML techniques
with 91.67%, 95.45%, and 94.12% for sensitivity, specificity, and accuracy,
respectively. Features from PPG and arteriograph able to be used to predict hyperuricemia
accurately and noninvasively. This study is the first to find the relationship
of PPG with hyperuricemia. It shows a significant relation between PPG signals and
arteriograph data toward the UA level. The proposed method of UA prediction shows
its potential for noninvasive preliminary assessment.
