The main purpose of this study was to determine the occurrence of non-ischemic cardiac injury using cardiac magnetic resonance (CMR) imaging in patients with persistent cardiac symptoms following recovery from COVID-19 pneumonia. We conducted a single-center, cross-sectional study. Between January 2021 and May 2021, we enrolled 121 patients with a recent COVID-19 infection and persistent cardiac symptoms. Study participants were divided into those who required hospitalization during the acute phase of SARS-CoV-2 infection (n = 58; 47.9%) and those non-hospitalized (n = 63; 52.1%). Non-ischemic cardiac injury (defined as the presence of late gadolinium enhancement (LGE) lesion and\/or active myocarditis in CMR) was detected in over half of post-COVID-19 patients (n = 64; 52.9%). LGE lesions were present in 63 (52.1%) and active myocarditis in 10 (8.3%) post-COVID-19 study participants. The majority of LGE lesions were located in the left ventricle at inferior and inferolateral segments at the base. There were no significant differences in the occurrence of LGE lesions (35 (60.3%) vs. 28 (44.4%); p = 0.117) or active myocarditis (6 (10.3%) vs. 4 (6.3%); p = 0.517) between hospitalized and non-hospitalized post-COVID-19 patients. However, CMR imaging revealed lower right ventricular ejection fraction (RVEF; 49.5 (44; 54) vs. 53 (50; 58) %; p = 0.001) and more frequent presence of reduced RVEF (60.3% vs. 33.3%; p = 0.005) in the former subgroup. In conclusion, more than half of our patients presenting with cardiac symptoms after a recent recovery from COVID-19 pneumonia had CMR imaging abnormalities indicating non-ischemic cardiac injury. The most common finding was LGE, while active myocarditis was detected in the minority of patients. CMR imaging abnormalities were observed both in previously hospitalized and non-hospitalized post-COVID-19 patients. Further research is needed to determine the long-term cardiovascular consequences of COVID-19 infection and the optimal management of patients with suspected post-COVID-19 non-ischemic cardiac injury.<\/jats:p>","DOI":"10.3390\/biology11121848","type":"journal-article","created":{"date-parts":[[2022,12,19]],"date-time":"2022-12-19T05:55:43Z","timestamp":1671429343000},"page":"1848","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["Cardiac Magnetic Resonance Findings in Patients Recovered from COVID-19 Pneumonia and Presenting with Persistent Cardiac Symptoms: The TRICITY-CMR Trial"],"prefix":"10.3390","volume":"11","author":[{"given":"Dagmara","family":"Wojtowicz","sequence":"first","affiliation":[{"name":"Department of Cardiology and Internal Medicine, Institute of Maritime and Tropical Medicine, Medical University of Gda\u0144sk, 81-519 Gdynia, Poland"},{"name":"Department of Noninvasive Cardiac Diagnostics, Medical University of Gda\u0144sk, 80-211 Gda\u0144sk, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5226-8311","authenticated-orcid":false,"given":"Karolina","family":"Dorniak","sequence":"additional","affiliation":[{"name":"Department of Noninvasive Cardiac Diagnostics, Medical University of Gda\u0144sk, 80-211 Gda\u0144sk, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Marzena","family":"\u0141awrynowicz","sequence":"additional","affiliation":[{"name":"Department of Cardiology and Internal Medicine, Institute of Maritime and Tropical Medicine, Medical University of Gda\u0144sk, 81-519 Gdynia, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Piotr","family":"W\u0105\u017c","sequence":"additional","affiliation":[{"name":"Department of Nuclear Medicine, Medical University of Gda\u0144sk, 80-210 Gda\u0144sk, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jadwiga","family":"Fija\u0142kowska","sequence":"additional","affiliation":[{"name":"Second Department of Radiology, Medical University of Gda\u0144sk, 80-214 Gda\u0144sk, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Dorota","family":"Kulawiak-Ga\u0142\u0105ska","sequence":"additional","affiliation":[{"name":"Department of Radiology, Medical University of Gda\u0144sk, 80-214 Gda\u0144sk, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Joanna","family":"Rejszel-Baranowska","sequence":"additional","affiliation":[{"name":"Department of Cardiology and Internal Medicine, Institute of Maritime and Tropical Medicine, Medical University of Gda\u0144sk, 81-519 Gdynia, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Robert","family":"Knut","sequence":"additional","affiliation":[{"name":"Department of Cardiology and Internal Medicine, Institute of Maritime and Tropical Medicine, Medical University of Gda\u0144sk, 81-519 Gdynia, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Maciej","family":"Haberka","sequence":"additional","affiliation":[{"name":"Department of Cardiology, School of Health Sciences, Medical University of Silesia, 40-055 Katowice, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7042-4381","authenticated-orcid":false,"given":"Edyta","family":"Szurowska","sequence":"additional","affiliation":[{"name":"Second Department of Radiology, Medical University of Gda\u0144sk, 80-214 Gda\u0144sk, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6460-4802","authenticated-orcid":false,"given":"Marek","family":"Kozi\u0144ski","sequence":"additional","affiliation":[{"name":"Department of Cardiology and Internal Medicine, Institute of Maritime and Tropical Medicine, Medical University of Gda\u0144sk, 81-519 Gdynia, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,12,18]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1449","DOI":"10.1002\/jmv.26424","article-title":"Epidemiology of COVID-19: A systematic review and meta-analysis of clinical characteristics, risk factors, and outcomes","volume":"93","author":"Li","year":"2021","journal-title":"J.
