Electrocardiographic manifestations of COVID-19: Effect on cardiac activation and repolarization.

Background: Prolonged QT intervals are reported in patients with COVID-19. Additionally, virus particles in heart tissue and abnormal troponin levels have been reported. Consequently, we hypothesize that cardiac electrophysiologic abnormalities may be associated with COVID-19.

Reduced cardiac function is associated with cardiac injury and mortality risk in hospitalized COVID-19 Patients.

Background: Cardiac injury is common in COVID-19 patients and is associated with increased mortality. However, it remains unclear if reduced cardiac function is associated with cardiac injury, and additionally if mortality risk is increased among those with reduced cardiac function in COVID-19 patients.

Hypothesis: The aim of this study was to assess cardiac function among COVID-19 patients with and without biomarkers of cardiac injury and to determine the mortality risk associated with reduced cardiac function.

Prevalence of SARS-CoV-2 Infection Among Health Care Workers in a Tertiary Community Hospital.

This cross-sectional study assesses the rate of COVID-19 infection among health care workers in a large community hospital.

A randomized study of the safety and efficacy of fondaparinux versus placebo in the prevention of venous thromboembolism after coronary artery bypass graft surgery.

Unlabelled: Venous thromboembolism (VTE) after coronary artery bypass graft (CABG) surgery may increase the postoperative morbidity and mortality. Therefore, we examined the current postoperative need for prophylactic antithrombotic therapy after CABG surgery.

Methods: This randomized, placebo-controlled, double-blind study was designed to compare the safety and efficacy of fondaparinux versus placebo in the prevention of VTE after CABG surgery.

Rural interhospital transfer of ST-elevation myocardial infarction patients for percutaneous coronary revascularization: the Stat Heart Program.

Background: In Europe, interhospital transfer of ST-elevation myocardial infarction (STEMI) patients for primary percutaneous coronary intervention (PCI) from non-PCI-capable (STEMI-referral) to PCI-capable (STEMI-accepting) facilities has been shown to be a superior reperfusion strategy compared with on-site fibrinolysis. The feasibility of such programs in the United States remains poorly defined.

Methods And Results: We describe an observational cohort of 230 consecutive presumed STEMI patients who underwent interhospital transfer between January 2005 and March 2007 among 6 STEMI-referral and 2 STEMI-accepting hospitals in rural central Illinois.
