Remdesivir associated sinus bradycardia in patients with COVID-19: A prospective longitudinal study

Background: Remdesivir is effective against SARS-Cov-2 with little evidence of its adverse effect on the cardiac system. The aim of the present study is investigating the incidence of bradycardia in COVID-19 patients treated with Remdesivir.Methods: This prospective longitudinal study was conducted in a tertiary center on COVID-19 patients for Remdesivir therapy. The objectives were to investigate the incidence of sinus bradycardia, and also the association between their demographics, underlying diseases, and the disease severity with developing bradycardia in COVID-19 patients treated with Remdesivir.Results: Of 177 patients, 44% were male. The mean (±standard deviation) age of patients was 49.79 ± 15.16 years old. Also, 33% were hospitalized due to more severe symptoms. Oxygen support was required for all hospitalized subjects. A total of 40% of the patients had comorbidities, with the most common comorbidity being hypertension. The overall incidence of bradycardia (heart rate<60 bpm) in patients receiving Remdesivir was 27%, of whom 70% had extreme bradycardia (heart rate <50 bpm). There was also a statistically significant reduction in heart rate after five doses of Remdesivir compared to the baseline heart rates. In the multivariable model, none of the covariates including age above 60 years, female sex, CRP>50 mg/L, O2 saturation<90%, underlying cardiovascular disease, hypertension and diabetes mellitus, and beta-blockers were associated with Remdesivir-induced bradycardia. No association was found between the COVID-19 severity indicators and bradycardia.Conclusion: As sinus bradycardia is a prevalent adverse cardiac effect of Remdesivir, it is recommended that all COVID-19 patients receiving Remdesivir, be evaluated for heart rate based on examination; and in the case of bradyarrhythmia, cardiac monitoring should be performed during administration to prevent adverse drug reactions

Bronchial Artery Embolization for Life-Threatening Hemoptysis in COVID-19 Patients

After the outbreak of the novel coronavirus at the end of December 2019 in China, it has become a global pandemic. Clinical manifestation of COVID-19 has a wide range of presentations ranging from asymptomatic to severe multi-organ involvement. Hemoptysis appears to be one of the major manifestations of severe acute respiratory syndrome that is related to COVID-19 infection. The occurrence of hemoptysis is multifactorial. However, massive hemoptysis is usually related to pulmonary aspergillosis or severe bronchiectasis due to corticosteroid pulse therapy which can be life-threatening. This manuscript presents five cases of successful life-saving bronchial artery embolization in patients with COVID-19 infection who were suffering from massive hemoptysis that were mostly related to aspergillosis and bronchiectasis. These cases are followed by a review of the literature.12 month embargo; first published 19 May 2022This item from the UA Faculty Publications collection is made available by the University of Arizona with support from the University of Arizona Libraries.

The Outcome of Patients with Pulmonary Arterial Hypertension and Chronic Thromboembolic Pulmonary Hypertension during the COVID-19 Pandemic

Background: The coronavirus 2019 (COVID-19) has affected the lives of many people worldwide. Patients with chronic underlying morbidities are vulnerable to get the severe form of the infection. The goal of this study was to evaluate the outcome of patients with pulmonary arterial hypertension during the COVID-19 pandemic in Iran. Methods: This cross-sectional study was conducted at a large tertiary center for pulmonary artery hypertension (PAH) patients. The primary end point was the prevalence of SARS-CoV-2 infection in PAH patients. The secondary end points were investigating the severity and mortality of COVID-19 infection in PAH patients during the COVID-19 pandemic. Results: Totally 75 patients were enrolled in the study from December 2019 to October 2021 and 64% were female. The mean ± SD age was 49 ± 16 years. The prevalence of COVID-19 in PAH/chronic thromboembolic pulmonary hypertension patients was 44%. About 66.7% of patients had comorbidities, which was a prognostic factor for COVID-19 infection in PAH patients (P < 0.001). Fifty-six percent of infected patients were asymptomatic. The most reported symptoms in symptomatic patients were fever (28%) and malaise (29%). Twelve percent of patients were admitted with severe symptoms. The mortality rate in infected individuals was 3.7%. Conclusions: COVID-19 infection in PAH/chronic thromboembolic pulmonary hypertension patients seems to be associated with high mortality and morbidity. More scientific proof is needed to clarify different aspect of COVID-19 infection in this population12 month embargo; first published 23 March 2023This item from the UA Faculty Publications collection is made available by the University of Arizona with support from the University of Arizona Libraries.
