However, the inherent invasiveness of any endovascular procedure introduces the risk of coronary vessel and myocardial damage.<\/jats:p>\n                  <jats:p>AIM<\/jats:p>\n                  <jats:p>To evaluate the utility of a novel electrocardiographic metric in detecting subtle myocardial injuries after coronary stenting.<\/jats:p>\n                  <jats:p>METHODS<\/jats:p>\n                  <jats:p>This investigation was conducted in 2021 at the Kyiv Heart Institute of the Ministry of Healthcare of Ukraine. The study involved 23 patients who underwent PCI, each subjected to a meticulous preoperative examination. A paired measurement approach was employed, encompassing 3-minutes electrocardiogram (ECG) recordings both before and several hours following the operation, using a compact ECG device. Each pair of ECG underwent a thorough analysis, scrutinizing 240 primary and computed ECG parameters.<\/jats:p>\n                  <jats:p>RESULTS<\/jats:p>\n                  <jats:p>The analysis delineated a distinct subgroup exhibiting significant myocardial damage post-stenting. This subgroup was characterized by an older average age and more stents than their counterparts. Notably, a concurrent reduction in the psychoemotional state index was observed alongside the ECG alterations in these patients, suggesting a correlation between myocardial damage and psychoemotional distress. Introducing a new electrocardiographic index has illuminated the often-subtle myocardial damage incurred during PCI.<\/jats:p>\n                  <jats:p>CONCLUSION<\/jats:p>\n                  <jats:p>The newly devised electrocardiographic metric is a significant advancement in the early detection of myocardial damage following PCI, able to capture not only physiological but also psychoemotional changes.<\/jats:p>","DOI":"10.4330\/wjc.v17.i12.112141","type":"journal-article","created":{"date-parts":[[2025,12,24]],"date-time":"2025-12-24T02:38:21Z","timestamp":1766543901000},"source":"Crossref","is-referenced-by-count":2,"title":["Mild myocardial injury during percutaneous coronary intervention based on minor changes on electrocardiogram and heart rate variability"],"prefix":"10.4330","volume":"17","author":[{"given":"Illya A","family":"Chaikovsky","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dmytro O","family":"Dziuba","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Olga A","family":"Kryvova","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kyrylo S","family":"Malakhov","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Oleksandr P","family":"Romanchuk","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Borys M","family":"Todurov","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"\u041eleg A","family":"Loskutov","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"2060","published-online":{"date-parts":[[2025,12,26]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","DOI":"10.5334\/aogh.2713"},{"key":"B2","doi-asserted-by":"publisher","DOI":"10.1161\/CIR.0000000000000558"},{"key":"B3","doi-asserted-by":"publisher","DOI":"10.1161\/01.cir.56.4.552"},{"key":"B4","doi-asserted-by":"publisher","DOI":"10.31928\/2664-4479-2024.1.733"},{"key":"B5","doi-asserted-by":"publisher","DOI":"10.1111\/j.1755-5922.2010.00155.x"},{"key":"B6","doi-asserted-by":"publisher","DOI":"10.1016\/s0002-8703(77)80310-4"},{"key":"B7","doi-asserted-by":"publisher","DOI":"10.1093\/eurheartj\/ehq393"},{"key":"B8","doi-asserted-by":"publisher","DOI":"10.1016\/s0735-1097(97)00506-8"},{"key":"B9","doi-asserted-by":"publisher","DOI":"10.1016\/j.socscimed.2020.113426"},{"key":"B10","doi-asserted-by":"publisher","DOI":"10.15407\/visn2021.02.033"},{"key":"B11","doi-asserted-by":"publisher","DOI":"10.1080\/17434440.2020.1754795"},{"key":"B12","unstructured":"Method of ECG evaluating based on universal scoring system.
