In response to this shortcoming, we propose to collect the wrist photoplethysmograph (PPG) signal and create models to predict the indicators of atherosclerosis (cardiovascular age and right brachial and ankle pulse wave velocity (baPWV)). This study uses the maximum correlation coefficient method for feature selection and establishes multiple models to predict cardiovascular age and the right baPWV. The study results show that the prediction of cardiovascular age using the backpropagation (BP) neural network model is the best. Its Pearson correlation coefficient (PCC) is 0.9501 (<jats:inline-formula>\n                     <a:math xmlns:a=\"http:\/\/www.w3.org\/1998\/Math\/MathML\" id=\"M1\">\n                        <a:mi>P<\/a:mi>\n                        <a:mo>&lt;<\/a:mo>\n                        <a:mn>0.05<\/a:mn>\n                     <\/a:math>\n                  <\/jats:inline-formula>), and the model finds the best six physiological features as crest time (CT), crest time ratio (CTR), slop K, stiffness index (SI), reflection index (RI), and heart rate (HR). When predicting the right baPWV value on the right side, we propose a hybrid method MLR_BP, which has better experimental results than BP and MLR. The MLR_BP model improves the prediction accuracy, the predicted PCC value is 0.9204 (<jats:inline-formula>\n                     <c:math xmlns:c=\"http:\/\/www.w3.org\/1998\/Math\/MathML\" id=\"M2\">\n                        <c:mi>P<\/c:mi>\n                        <c:mo>&lt;<\/c:mo>\n                        <c:mn>0.05<\/c:mn>\n                     <\/c:math>\n                  <\/jats:inline-formula>), and the model only needs two features, HR and cardiovascular age. This study further verified the results of related literature and proved the relationship between AS and related physiological parameters. The proposed method is applied to wearable devices and has an application value for diagnosing AS and preventing cardiovascular diseases.<\/jats:p>","DOI":"10.1155\/2021\/2234514","type":"journal-article","created":{"date-parts":[[2021,12,1]],"date-time":"2021-12-01T23:05:12Z","timestamp":1638399912000},"page":"1-9","source":"Crossref","is-referenced-by-count":0,"title":["The Prediction of Atherosclerosis Index Based on Photoplethysmograph"],"prefix":"10.1155","volume":"2021","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7085-1789","authenticated-orcid":true,"given":"Yibing","family":"Li","sequence":"first","affiliation":[{"name":"School of Computer Science and Technology, Hefei Normal University, Hefei 230601, China"},{"name":"University of Science and Technology of China, Hefei 230031, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6104-1015","authenticated-orcid":true,"given":"Fei","family":"Xie","sequence":"additional","affiliation":[{"name":"School of Computer Science and Technology, Hefei Normal University, Hefei 230601, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6503-2711","authenticated-orcid":true,"given":"Xiaoye","family":"Ren","sequence":"additional","affiliation":[{"name":"School of Computer Science and Technology, Hefei Normal University, Hefei 230601, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4005-069X","authenticated-orcid":true,"given":"Fenyun","family":"Cao","sequence":"additional","affiliation":[{"name":"School of Computer Science and Technology, Hefei Normal University, Hefei 230601, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","reference":[{"key":"1","doi-asserted-by":"publisher","DOI":"10.1088\/0967-3334\/35\/8\/1521"},{"key":"2","doi-asserted-by":"publisher","DOI":"10.11909\/j.issn.1671-5411.2020.01.001"},{"key":"3","doi-asserted-by":"publisher","DOI":"10.1111\/jfbc.13200"},{"key":"4","doi-asserted-by":"publisher","DOI":"10.1161\/CIRCULATIONAHA.107.699579"},{"key":"5","doi-asserted-by":"publisher","DOI":"10.1097\/mbp.0000000000000490"},{"key":"6","doi-asserted-by":"publisher","DOI":"10.1080\/10641963.2018.1545853"},{"key":"7","doi-asserted-by":"publisher","DOI":"10.1093\/eurheartj\/ehl254"},{"key":"8","doi-asserted-by":"publisher","DOI":"10.3390\/s18061894"},{"key":"9","doi-asserted-by":"publisher","DOI":"10.3390\/jcm7100316"},{"key":"10","doi-asserted-by":"publisher","DOI":"10.1080\/00016489.2019.1668569"},{"key":"11","doi-asserted-by":"publisher","DOI":"10.1109\/tmi.2019.2926141"},{"key":"12","doi-asserted-by":"publisher","DOI":"10.1109\/comsnets48256.2020.9027457"},{"key":"13","doi-asserted-by":"publisher","DOI":"10.1109\/tii.2020.2975222"},{"key":"14","doi-asserted-by":"publisher","DOI":"10.1088\/0967-3334\/36\/9\/1801"},{"key":"15","doi-asserted-by":"publisher","DOI":"10.1016\/j.bspc.2016.12.005"},{"key":"16","doi-asserted-by":"publisher","DOI":"10.1145\/3292500"},{"key":"17","doi-asserted-by":"publisher","DOI":"10.1109\/access.2020.2968967"},{"key":"18","doi-asserted-by":"publisher","DOI":"10.1097\/01.hjh.0000239277.05068.87"},{"key":"19","doi-asserted-by":"publisher","DOI":"10.1016\/j.atherosclerosis.2010.08.075"},{"key":"20","doi-asserted-by":"publisher","DOI":"10.5551\/jat.3616"}],"container-title":["Scientific Programming"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/downloads.hindawi.com\/journals\/sp\/2021\/2234514.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/sp\/2021\/2234514.xml","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/sp\/2021\/2234514.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2021,12,1]],"date-time":"2021-12-01T23:05:22Z","timestamp":1638399922000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.hindawi.com\/journals\/sp\/2021\/2234514\/"}},"subtitle":[],"editor":[{"given":"Shah","family":"Nazir","sequence":"additional","affiliation":[],"role":[{"role":"editor","vocabulary":"crossref"}]}],"short-title":[],"issued":{"date-parts":[[2021,12,1]]},"references-count":20,"alternative-id":["2234514","2234514"],"URL":"https:\/\/doi.org\/10.1155\/2021\/2234514","relation":{},"ISSN":["1875-919X","1058-9244"],"issn-type":[{"type":"electronic","value":"1875-919X"},{"type":"print","value":"1058-9244"}],"subject":[],"published":{"date-parts":[[2021,12,1]]}}}
