Besides nuclear imaging and subsequent coronary angiography (CAG), no blood test can indicate whether dysregulated homeostasis is associated with stress-induced myocardial perfusion defects. This study investigated the expression signature of long noncoding RNAs (lncRNAs) and genes involved in vascular inflammation and stress response in the blood of patients with stress-induced myocardial perfusion abnormalities (n = 27). The results revealed an expression signature consisting of the upregulation of RMRP (p &lt; 0.01) and downregulations of THRIL (p &lt; 0.01) and HIF1A (p &lt; 0.01) among patients with a positive thallium stress test and no significant coronary artery stenosis within 6 months after baseline treatment. We developed a scoring system based on the expression signatures of RMRP, MIAT, NTT, MALAT1, HSPA1A, and NLRP3 to predict the need for further CAG among patients with moderate-to-significant stress-induced myocardial perfusion defects (area under the receiver operating characteristic curve = 0.963). Therefore, we identified a dysregulated expression profile of lncRNA-based genes in the blood that could be valuable for the early detection of vascular homeostasis imbalance and personalized therapy.<\/jats:p>","DOI":"10.3390\/biom13050849","type":"journal-article","created":{"date-parts":[[2023,5,18]],"date-time":"2023-05-18T08:09:44Z","timestamp":1684397384000},"page":"849","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Association of Long Noncoding RNA Expression Signatures with Stress-Induced Myocardial Perfusion Defects"],"prefix":"10.3390","volume":"13","author":[{"given":"Yu-Chieh","family":"Chang","sequence":"first","affiliation":[{"name":"Division of Nuclear Medicine, China Medical University Hsinchu Hospital, Zhubei City 302, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jun-Ting","family":"Liou","sequence":"additional","affiliation":[{"name":"Division of Cardiology, China Medical University Hsinchu Hospital, Zhubei City 302, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yu-Min","family":"Peng","sequence":"additional","affiliation":[{"name":"Integrated Precision Health and Immunodiagnostic Center, Department of Laboratory Medicine, China Medical University Hsinchu Hospital, Zhubei City 302, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Guan-Jun","family":"Chen","sequence":"additional","affiliation":[{"name":"Integrated Precision Health and Immunodiagnostic Center, Department of Laboratory Medicine, China Medical University Hsinchu Hospital, Zhubei City 302, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2705-9742","authenticated-orcid":false,"given":"Chien-Yu","family":"Lin","sequence":"additional","affiliation":[{"name":"Integrated Precision Health and Immunodiagnostic Center, Department of Laboratory Medicine, China Medical University Hsinchu Hospital, Zhubei City 302, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chin-An","family":"Yang","sequence":"additional","affiliation":[{"name":"Integrated Precision Health and Immunodiagnostic Center, Department of Laboratory Medicine, China Medical University Hsinchu Hospital, Zhubei City 302, Taiwan"},{"name":"College of Medicine, China Medical University, Taichung 404, Taiwan"},{"name":"Department of Biomedical Engineering and Environmental Sciences, National Tsing Hua University, Hsinchu City 300, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2023,5,17]]},"reference":[{"key":"ref_1","first-page":"192","article-title":"Interpreting myocardial perfusion scintigraphy using single-photon emission computed tomography.
