ABSTRACT
Methods and results A 79-year-old woman, with a history of subclinical hypothyroidism, obesity and smoke presented to the Emergency Room with dyspnoea and cold sweating. She had undergone her first dose of COVID-19 Moderna mRna vaccination just four days prior to her admission. She showed elevated HS troponin and elevated BNP at her laboratory exams. Her 12-lead ECG showed T wave inversion in the antero-lateral leads and prolongued QTc. Her transthoracic echocardiogram showed severe ejection fraction reduction due to hypokinesia of the mid-apical segments of the anterior and lateral walls of the heart. The patient was then admitted to the Cardiology ward in order to perform a coronary angiography which sowed no significant coronary stenosis. She was started on appropriate medication and discharged after a six day in-hospital stay. At discharge she showed partial recovery of her ejection fraction (EF 44%). A cardiac magnetic resonance was performed after discharge which showed no late gadolinium enhancement. Such finding allowed us to rule out the diagnosis of myocarditis. Moreover at her 3-month follow-up her ejection fraction had recovered completely. We concluded for the diagnosis of Takotsubo Syndrome secondary to vaccination. Conclusions We presented a case of Takotsubo syndrome after vaccination with the Moderna vaccine for COVID-19. Two other similar case reports can be found in current medical literature. Female sex, post-menopausal age and the inevitable psychological stress derived by the pandemic and the vaccination may have triggered the condition.
ABSTRACT
From 2020, many countries have adopted several restrictions to limit the COVID-19 pandemic. The forced containment impacted on healthcare organizations and the everyday life of patients with heart disease. We prospectively analyzed data recorded from implantable defibrillators and/or cardiac resynchronization devices of Italian patients during the lockdown (LDP), post-lockdown period (PLDP) and a control period (CP) of the previous year. We analyzed device data of the period 9 March 2019-31 May 2020 of remotely monitored patients from 34 Italian centers. Patients were also categorized according to areas with high/low infection prevalence. Among 696 patients, we observed a significant drop in median activity in LDP as compared to CP that significantly increased in the PLDP, but well below CP (all p < 0.0001). The median day heart rate and heart rate variability showed a similar trend. This behavior was associated during LDP with a significant increase in the burden of atrial arrhythmias (p = 0.0150 versus CP) and of ventricular arrhythmias [6.6 vs. 1.5 per 100 patient-weeks in CP; p = 0.0026]; the latter decreased in PLDP [0.3 per 100 patient-weeks; p = 0.0035 vs. LDP]. No modifications were recorded in thoracic fluid levels. The high/low prevalence of COVID-19 infection had no significant impact. We found an increase in the arrhythmic burden in LDP coupled with a decrease in physical activity and heart rate variability, without significant modifications of transthoracic impedance, independent from COVID-19 infection prevalence. These findings suggest a negative impact of the COVID-19 pandemic, probably related to lockdown restrictions.
ABSTRACT
The prediction and prevention of sudden cardiac death is the philosopher's stone of clinical cardiac electrophysiology. Sports can act as triggers of fatal arrhythmias and therefore it is essential to promptly frame the athlete at risk and to carefully evaluate the suitability for both competitive and recreational sports activity. A history of syncope or palpitations, the presence of premature ventricular complexes or more complex arrhythmias, a reduced left ventricular systolic function, or the presence of known or familiar heart disease should prompt a thorough evaluation with second level examinations. In this regard, cardiac magnetic resonance and electrophysiological study play important roles in the diagnostic work-up. The role of genetics is increasing both in cardiomyopathies and in channelopathies, and a careful evaluation must be focused on genotype positive/phenotype negative subjects. In addition to being a trigger for fatal arrhythmias in certain cardiomyopathies, sports also play a role in the progression of the disease itself, especially in the case arrhythmogenic right ventricular cardiomyopathy. In this paper, we review the latest European guidelines on sport cardiology in patients with cardiovascular diseases, focusing on arrhythmic risk stratification and the management of cardiomyopathies and channelopathies.

Myocardial inflammation is an important cause of cardiovascular morbidity and sudden cardiac death in athletes. The relationship between sports practice and myocardial inflammation is complex, and recent data from studies concerning cardiac magnetic resonance imaging and endomyocardial biopsy have substantially added to our understanding of the challenges encountered in the comprehensive care of athletes with myocarditis or inflammatory cardiomyopathy (ICM). In this review, we provide an overview of the current knowledge on the epidemiology, pathophysiology, diagnosis, and treatment of myocarditis, ICM, and myopericarditis/perimyocarditis in athletes, with a special emphasis on arrhythmias, patient-tailored therapies, and sports eligibility issues.

BACKGROUND: In the early stages of COVID-19 pneumonia, hypoxemia has been described in absence of dyspnea ("silent" or "happy" hypoxemia). Our aim was to report its prevalence and outcome in a series of hypoxemic patients upon Emergency Department admission. METHODS: In this retrospective observational cohort study we enrolled a study population consisting of 213 COVID-19 patients with PaO
