ABSTRACT

PURPOSE: Severely ill patients affected by coronavirus disease 2019 (COVID-19) develop circulatory failure. We aimed to report patterns of left and right ventricular dysfunction in the first echocardiography following admission to intensive care unit (ICU). METHODS: Retrospective, descriptive study that collected echocardiographic and clinical information from severely ill COVID-19 patients admitted to 14 ICUs in 8 countries. Patients admitted to ICU who received at least one echocardiography between 1st February 2020 and 30th June 2021 were included. Clinical and echocardiographic data were uploaded using a secured web-based electronic database (REDCap). RESULTS: Six hundred and seventy-seven patients were included and the first echo was performed 2 [1, 4] days after ICU admission. The median age was 65 [56, 73] years, and 71% were male. Left ventricle (LV) and/or right ventricle (RV) systolic dysfunction were found in 234 (34.5%) patients. 149 (22%) patients had LV systolic dysfunction (with or without RV dysfunction) without LV dilatation and no elevation in filling pressure. 152 (22.5%) had RV systolic dysfunction. In 517 patients with information on both paradoxical septal motion and quantitative RV size, 90 (17.4%) had acute cor pulmonale (ACP). ACP was associated with mechanical ventilation (OR > 4), pulmonary embolism (OR > 5) and increased PaCO2. Exploratory analyses showed that patients with ACP and older age were more likely to die in hospital (including ICU). CONCLUSION: Almost one-third of this cohort of critically ill COVID-19 patients exhibited abnormal LV and/or RV systolic function in their first echocardiography assessment. While LV systolic dysfunction appears similar to septic cardiomyopathy, RV systolic dysfunction was related to pressure overload due to positive pressure ventilation, hypercapnia and pulmonary embolism. ACP and age seemed to be associated with mortality in this cohort.

ABSTRACT

During the COVID-19 pandemic, government social marketing messages support strategies of suppression (often stay-at-home orders or lockdowns) and/or mitigation (through testing, isolation, and tracing). Success at lowering the virus reproduction rate (R0) depends on social marketing messaging that rapidly changes behaviors. This study explores a potential side effect of a successful antivirus public health messaging campaign, when employees are back at work but the virus threat has not disappeared, that leads to on-the-job stress. The authors surveyed office employees in Shanghai, the People's Republic of China, where a nearly 2-month COVID-19 quarantine ended in late March 2020 and work locations reopened with strong public health messaging to encourage cooperation with continued virus spread suppression strategies-an approach likely to be followed in numerous countries. This study examines the relationship of pandemic public messaging sensitivity with tension and negative emotions on the job. Canonical correlation analysis is used with a sample of 1154 respondents, 4 predictor variables (reference group, self-regulation, media, and risk), and 2 criterion variables (negative emotions and job tension). Results show employees are differentially affected by the pandemic background noise. Those more sensitive to social-level virus risks and more open to reference group influence report increased levels of negative emotions and work tension.
