Resumen
ESPINOSA, EZEQUIEL et al. Patterns of myocardial injury in patients recovered from COVID-19: findings on cardiac magnetic resonance imaging studies and their prognosis. Rev. argent. cardiol. [online]. 2022, vol.90, n.6, pp.421-428. Epub 01-Nov-2022. ISSN 1850-3748. http://dx.doi.org/10.7775/rac.es.v90.i6.20568.
Background:
COVID-19 continues to cause significant mortality and morbidity worldwide. Cardiac involvement is associated with long-term and medium-term negative clinical outcomes. Cardiac magnetic resonance imaging (CMRI) is a useful technique to detect and characterize myocardial disorders, so it has been used to identify different post-COVID-19 complications.
Objective:
This study was aimed to evaluate the presence, the type, and the 6-month prognosis of the CMRI findings in an unselected cohort of patients referred to our site.
Methods:
Single-center, prospective, observational cohort study. We included consecutive patients referred to our site for a CMRI. They were classified into five groups: normal CMRI (Group A), nonspecific myocardial fibrosis (Group B), isolated myocardial inflammation (Group C), myocarditis (Group D) and ischemic myocardial fibrosis (Group E). A 6-month followup was performed.
Results:
We enrolled 298 patients, 51% women. CMRI was performed at a median of 68 days following epidemiological discharge. Patients were assigned to the groups as follows: 64.5% to Group A, 21.8% to Group B, and 10.4% to Group C. CMRI was repeated in six patients, and it showed that altered basal levels returned to normal. Six patients in Group D (2%) were diagnosed with myocarditis, and four in Group E (1.3%) suffered from myocardial infarction. Two patients in Group E underwent a revascularization procedure during their follow-up. The remaining cohort did not suffer from any event.
Conclusion:
No pathological findings were found on most patients’ CMRI (86%). Given the scale of the pandemic, we do not consider advisable to assess post-COVID-19 cardiac complications in general population by means of CMRI. In contrast, CMRI should be performed on those patients suspected of myocardial injury.
