Cardiac involvement in patients 1 year after recovery from moderate and severe COVID-19 infections.

ABSTRACT:

Background

Some patients suffered persistent cardiac symptoms after hospital discharge following COVID-19 infection, including chest tightness, chest pain, and palpitation. However, the cardiac involvement in these patients remains unknown. The purpose of this study was to investigate the effect of COVID-19 infection on the cardiovascular system after 1 year of recovery in patients hospitalized with persistent cardiac symptoms.

Materials and methods

In this prospective observational study, a total of 32 patients who had COVID-19 (11 diagnosed as severe COVID-19 and 21 as moderate) with persistent cardiac symptoms after hospital discharge were enrolled. Contrast-enhanced cardiovascular magnetic resonance (CMR) imaging was performed on all patients. Comparisons were made with age- and sex-matched healthy controls (n = 13), and age-, sex- and risk factor-matched controls (n = 21). Further analysis was made between the severe and moderate COVID-19 cohorts.

Results

The mean time interval between acute COVID-19 infection and CMR was 462 ± 18 days. Patients recovered from COVID-19 had reduced left ventricular ejection fraction (LVEF) (p = 0.003) and increased extracellular volumes (ECVs) (p = 0.023) compared with healthy controls. Focal late gadolinium enhancement (LGE) was found in 22 (68.8%) patients, mainly distributed linearly in the septal mid-wall or patchily in RV insertion point. The LGE extent in patients with severe COVID-19 was higher than that in patients with moderate COVID-19 (p = 0.009).

Conclusion

This 1-year follow-up study revealed that patients with persistent cardiac symptoms, after recovering from COVID-19, had decreased cardiac function and increased ECV compared with healthy controls. Patients with COVID-19 predominately had a LGE pattern of septal mid-wall or RV insertion point. Patients with severe COVID-19 had greater LGE extent than patients with moderate COVID-19.

Project description:BackgroundThe role of bacterial and viral co-infection in the current COVID-19 pandemic remains elusive. The aim of this study was to describe the rates and features of co-infection on admission of COVID-19 patients, based on molecular and routine laboratory methods.MethodsA retrospective study of COVID-19 and non-COVID-19 patients undergoing Biofire®, FilmArray® Pneumonia Panel, bioMérieux, and routine cultures during the first 3 days from admission, between June 2019 and March 2021.ResultsFilmArray tests were performed in 115 COVID-19 and in 61 non-COVID-19 patients. Most (>99%) COVID-19 patients had moderate-critical illness, 37% required mechanical ventilation. Sputa and endotracheal aspirates were the main samples analyzed. Positive FilmArray tests were found in 60% (70/116) of the tests amongst COVID-19 patients and 62.5% (40/64) amongst non-COVID-19 patients. All 70 cases were positive for bacterial targets, while one concomitant virus (Rhinovirus/Enterovirus) and one Legionella spp. were detected. The most common bacterial targets were Haemophilus influenzae (36%), Staphylococcus aureus (23%), Streptococcus pneumoniae (10%) and Enterobacter cloacae (10%). Correlation between FilmArray and cultures was found in 81% and 44% of negative and positive FA tests, respectively. Positive FilmArray results typically (81%) triggered the administration of antibiotic therapy and negative results resulted in antimicrobials to be withheld in 56% of cases and stopped in 8%. Bacterial cultures of COVID-19 patients were positive in 30/88 (34%) of cases.ConclusionsBacterial co-infection is common amongst moderate-critical COVID-19 patients on admission while viral and atypical bacteria were exceedingly rare. Positive FilmArray results could trigger potentially unnecessary antibiotic treatment.KEY POINTWe found high rates of on-admission bacterial co-infection amongst hospitalized moderate to severe COVID-19 patients. Molecular tests (Biofire, FilmArray) and routine microbiological tests revealed 60% and 34% bacterial co-infection, respectively, while viral and fungal co-infections were rare.
