This study described the clinical features of 23 patients who after receiving the first dose of ChAdOx1 nCoV-19 vaccine developed atypical platelet factor 4 (PF4)-dependent thrombosis and/or thrombocytopenia that resembles heparin-induced thrombocytopenia.
Some cases of thrombotic events combined with thrombocytopenia have been described after COVID-19 vaccination with AZD1222. This thrombotic disorder clinically resembles heparin-induced thrombocytopenia, with a different serological profile.
Incidence of thrombotic complications remained high in hospitalized COVID-19 patients in the second wave. Thromboprophylaxis is therefore warranted in these patients.
Risk of overall mortality in COVID-19 patients was lower in the second wave, compared with the first wave. However, cumulative incidences of thrombotic complications remained high in the second wave.
Compared to the same period in 2019, cholesterol testing rate was almost 40% lower between March-September 2020 when analyzing data from a healthcare system in New England, USA.
Patients with HF admitted to hospital for COVID-19 had increased risk for in-hospital mortality and needed more often ICU care and intubation and mechanical ventilation compared to patients without HF.
This position paper discusses the cause and consequences of endothelial injury and dysfunction in COVID-19.
A study of 305 hospitalized COVID-19 patients showed that approximately two-third of patients with evidence of myocardial injuries had echocardiographic abnormalities. In these patients, risk of in-hospital mortality was increased.
This viewpoint article in JAMA reviews the latest findings on the risk of heart failure, particularly HFpEF, in those who developed acute COVID-19 and those who have recovered from the illness.
AHA 2020 Anthony Fauci gives a presentation on COVID-19: Public health and scientific challenges.
Changes in the structure of primary care delivery, and differences in content of telemedicine visits vs. office-based visits were observed in the USA during the COVID-19 pandemic.
ESC 2020 BRACE CORONA was a randomized trial that tested two strategies in hospitalized patients with COVID-19 who were on ACEi or ARBs: Temporarily suspending or continuing ACEi/ARBs. Prof. Lopes discusses the results.
