ABSTRACT
Background: Conflicting results on the cardiovascular involvement after SARS-CoV-2 infection generated concerns on the safety of return-to-play (RTP) in the athletic population. However, these data are mainly based on Troponin and imaging findings. Purpose: Aim of the study was to evaluate the prevalence of cardiac involvement after COVID-19 in Olympic athletes, who had previously been screened in our pre-participation program. Methods: Since November 2020, all consecutive Olympic athletes presented to our Institute after COVID-19 prior RTP were enrolled. The protocol was dictated by the Italian governing bodies and comprised: 12-lead ECG, blood test, cardiopulmonary exercise test (CPET), 24-hours ECG monitoring, spirometry. Cardiovascular Magnetic Resonance (CMR) was also performed. All Athletes were previously screened in our Institute as part of their periodical pre-participation evaluation. Results: Forty-seven Italian Olympic athletes were enrolled: 83% asymptomatic, 13% mildly asymptomatic, 4% had pneumonia. The evaluation was performed after a median of 9 days from negative SARS-CoV-2 swab. Uncommon premature ventricular contractions (PVCs) were found in 13% athletes, however, only 6% (n=3) were newly detected. All newly diagnosed uncommon PVCs were detected by CPET. One of these three athletes had evidence for acute myocarditis by CMR, along with Troponin raise;another had mild pericardial effusion. No one of the remaining athletes had abnormalities detected by CMR (Figure). Conclusions: Cardiac abnormalities in Olympic athletes screened after COVID-19 resolution were detected in a minority and were associated with new ventricular arrhythmias. Only one had evidence for acute myocarditis (in presence of symptoms and elevated biomarkers). No one of the remaining athletes had abnormalities by imaging or laboratory test. Our data support the efficacy of the clinical assessment including exercise-ECG to raise suspicion for cardiovascular abnormalities after COVID-19. Instead, the routine use of CMR as a screening tool appears not justified. (Figure Presented).
ABSTRACT
In Italy COVID-19 pandemic had a severe impact. The homeless live in situations aggravating their poor health conditions and comorbidities. Although homeless people are a fragile category, no dedicated measures by public health departments seem to be applied infrequently to this population. For these reasons, they are probably one of the categories most affected by the global spread of the SARS-CoV-2. Moreover, the current vaccination campaign against COVID-19 can represent an important opportunity for health and social integration also for the homeless. This scoping review performed a map to describe strategies and interventions adopted to protect the homeless population during the COVID-19 pandemic in Italy. The methodology adheres to the PRISMA statement (extension for purpose revision) and follows the framework of Arksey and O'Malley. At the end of the selection process, 7 studies deemed relevant were included. Many strategies have been adopted to counter the spread of the virus to the homeless population, such as rapid and molecular tests with swabs or rapid blood tests. All the tests for diagnosing the infection currently in use have also been used for the homeless.
