The novel coronavirus disease 2019 (COVID-19) is associated with several cardiovascular manifestations including myocardial injury, myocarditis, arrhythmia, and pulmonary embolism. Rare cases of stress-induced cardiomyopathy, or takotsubo syndrome have also been reported during the acute infection, and secondary to stress following lockdown and self-isolation. Diagnosis in the setting of the acute infection is challenging since conventional imaging modalities such as transthoracic echocardiography and coronary angiography should be restricted to minimize physician-patient contact until the patients is tested negative for COVID-19. ⋯ The overall course of the disease seems to be similar to takotsubo in the general population. Physicians should be familiar with the clinical presentation, possible complications, and management of takotsubo during COVID-19 outbreak. Here, we review the special considerations in the diagnosis and management of takotsubo syndrome during the current pandemic.

Randomized Controlled Trial Multicenter Study
Early Remdesivir to Prevent Progression to Severe Covid-19 in Outpatients.
Remdesivir improves clinical outcomes in patients hospitalized with moderate-to-severe coronavirus disease 2019 (Covid-19). Whether the use of remdesivir in symptomatic, nonhospitalized patients with Covid-19 who are at high risk for disease progression prevents hospitalization is uncertain. ⋯ Among nonhospitalized patients who were at high risk for Covid-19 progression, a 3-day course of remdesivir had an acceptable safety profile and resulted in an 87% lower risk of hospitalization or death than placebo. (Funded by Gilead Sciences; PINETREE ClinicalTrials.gov number, NCT04501952; EudraCT number, 2020-003510-12.).

Clinical Effect of Hepatitis B Virus on COVID-19 Infected Patients: A Nationwide Population-Based Study Using the Health Insurance Review & Assessment Service Database.
Several studies have recently suggested that liver disease and cirrhosis were risk factors for poor outcomes in patients with coronavirus disease 2019 (COVID-19) infections. However, no large data study has reported the clinical course of COVID-19 patients with chronic hepatitis B virus (HBV) infections. This study investigated whether HBV infection had negative impacts on the clinical outcomes of COVID-19 patients. ⋯ COVID-19-infected patients with HBV infections showed worse clinical courses than non-HBV-infected COVID-19 patients. However, after adjustment, chronic HBV infection itself does not seem to affect the clinical outcomes in COVID-19 patients.

The development of pulmonary fibrosis is a rare complication of the novel coronavirus disease 2019 (COVID-19). Limited information is available in the literature about that, and the present study aimed to address this gap. This case-control study included 64 patients with post-COVID-19 pulmonary fibrosis who were hospitalized for COVID-19. ⋯ Half of the COVID-19 patients with pulmonary fibrosis (50%) who survived required oxygen therapy, and those with "honeycomb" lung required long-term oxygen therapy to a far greater extent than others. Cox regression revealed that smoking and asthma were significantly associated with ICU admission and the risk of mortality. Post-COVID-19 pulmonary fibrosis is a severe complication that leads to permanent lung damage or death.
