Material and methods: The study included 387 patients admitted to the clinic for a scheduled primary CABG. A seven-item questionnaire, \u201cPRISMA-7\u201d, was used to identify frail elderly patients before the procedure. We divided the study sample into two groups, taking into account the results of the survey: patients without frailty, n0 = 300 (77.5%), and patients with frailty, n1 = 87 (22.5%). The anamnestic and laboratory data, outcome of the surgical intervention, perioperative and early complications, and adverse outcomes were analyzed. Results: We detected frailty in 22.5% of the patients with CAD before the procedure. According to the anamnestic data and paraclinical and intraoperative findings, the groups of patients with and without frailty were comparable. The differences were revealed in the intraoperative and early postoperative periods of CABG. Thus, postoperative rhythm disturbances (19.5% vs. 10.5%, p = 0.025, V = 0.115, respectively) and transient ischemic attacks\/stroke (5.7% vs. 1.3%, p = 0.031, V = 0.122, respectively) occurred significantly more often among the frail patients. There were no significant differences between the groups in the frequency of other intraoperative and early postoperative complications. In the group of frail patients, four fatal outcomes due to early postoperative ischemia were recorded, and among patients without frailty, one fatal outcome was recorded (4.5% vs. 0.3%, p = 0.010, V = 0.156, respectively). At the 1-year follow-up visit, the presence of frailty in history served as a predictor of mortality (11.5% vs. 0.6%, p \u02c2 0.001, V = 0.290, respectively). Conclusion: The presence of frailty can be used as an independent predictor of an unfavorable prognosis in patients with CAD, both in the perioperative and early survival period after CABG. It should be taken into account during surgical risk assessment.<\/jats:p>","DOI":"10.3390\/diagnostics14131419","type":"journal-article","created":{"date-parts":[[2024,7,3]],"date-time":"2024-07-03T04:23:43Z","timestamp":1719980623000},"page":"1419","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Frailty as an Independent Predictor of Adverse Outcomes in Patients Undergoing Direct Myocardial Revascularization"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2384-5682","authenticated-orcid":false,"given":"Kristina","family":"Krivoshapova","sequence":"first","affiliation":[{"name":"Federal State Budgetary Institution \u201cResearch Institute for Complex Issues of Cardiovascular Diseases\u201d, Kemerovo 650002, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Daria","family":"Tsygankova","sequence":"additional","affiliation":[{"name":"Federal State Budgetary Institution \u201cResearch Institute for Complex Issues of Cardiovascular Diseases\u201d, Kemerovo 650002, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3023-6239","authenticated-orcid":false,"given":"Evgeny","family":"Bazdyrev","sequence":"additional","affiliation":[{"name":"Federal State Budgetary Institution \u201cResearch Institute for Complex Issues of Cardiovascular Diseases\u201d, Kemerovo 650002, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6981-9661","authenticated-orcid":false,"given":"Olga","family":"Barbarash","sequence":"additional","affiliation":[{"name":"Federal State Budgetary Institution \u201cResearch Institute for Complex Issues of Cardiovascular Diseases\u201d, Kemerovo 650002, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,7,3]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"87","DOI":"10.1093\/eurheartj\/ehy394","article-title":"2018 ESC\/EACTS Guidelines on myocardial revascularization","volume":"40","author":"Neumann","year":"2019","journal-title":"Eur.
