Electrocardiographic (ECG) changes have been associated with coronavirus disease 2019 (COVID-19) severity. However, the progression of ECG findings in patients with COVID-19 has not been studied. The purpose of this study was to describe ECG features at different stages of COVID-19 cardiovascular (CV) events and to examine the effects of specific ECG parameters and cardiac-related biomarkers on clinical outcomes in COVID-19. Retrospective, cohort study. Major tertiary-care medical centers and community hospitals in Louisville, KY. A total of 124 patients with COVID-19 and CV events during hospitalization. None. Twelve-lead ECG parameters, biomarkers of cardiac injuries, and clinical outcomes were analyzed with Spearman correlation coefficients and Kruskal-Wallis 1-way analysis of variance. Atrial fibrillation/atrial flutter was more frequent on the ECG obtained at the time of the CV event when compared with admission ECG (9.5% v 26.9%; p = 0.007). Sinus tachycardia was higher in the last available hospital ECG than the CV event ECG (37.5% v 20.4%; p = 0.031). Admission ECG-corrected QT interval was significantly associated with admission troponin levels (R = 0.52; p < 0.001). The last available hospital ECG showed nonsurvivors had longer QRS duration than survivors (114.6 v 91.2 ms; p = 0.026), and higher heart rate was associated with longer intensive care unit length of stay (Spearman ρ = 0.339; p = 0.032). In hospitalized patients with COVID-19 and CV events, ECGs at various stages of COVID-19 hospitalization showed significantly different features with dissimilar clinical outcome correlations.

To analyze outcomes and risk factors of cardiovascular events in a metropolitan coronavirus disease 2019 (COVID-19) database, and to perform a subgroup analysis in African American populations to determine whether outcomes and risk factors are influenced by race. Retrospective cohort analysis from March 9, 2020 to June 20, 2020. Population-based study in Louisville, KY, USA. Seven hundred adult inpatients hospitalized with COVID-19. N/A. This cohort consisted of 126 patients (18%) with cardiovascular events and 574 patients without cardiovascular events. Patients with cardiovascular events had a much higher mortality rate than those without cardiovascular events (45.2% v 8.7%, p < 0. 001). There was no difference between African American and white patients regarding mortality (43.9% v 46.3%, p = 1) and length of stay for survivors (11 days v 9.5 days, p = 0. 301). Multiple logistics regression analysis suggested that male, race, lower SaO2/F I O2, higher serum potassium, lower serum albumin, and number of cardiovascular comorbidities were highly associated with the occurrence of cardiovascular events in COVID-19 patients. Lower serum albumin and neoplastic and/or immune-compromised diseases were highly associated with cardiovascular events for African American COVID-19 patients. SaO2/F I O2 ratio and cardiovascular comorbidity count were significantly associated with cardiovascular events in white patients. Cardiovascular events were prevalent and associated with worse outcomes in hospitalized patients with COVID-19. Outcomes of cardiovascular events in African American and white COVID-19 patients were similar after propensity score matching analysis. There were common and unique risk factors for cardiovascular events in African American COVID-19 patients when compared with white patients. [ABSTRACT FROM AUTHOR]

Background: Malpractice in emergency medicine is of high concern for medical providers, the fear of which continues to drive decision-making. The body of evidence evaluating risk specific to emergency physicians is disjointed, and thus it remains difficult to derive cohesive themes and strategies for risk minimization.Objective: This review evaluates the state of malpractice in emergency medicine and summarizes a concise approach for the emergency physician to minimize risk.Discussion: The environment of the emergency department (ED) represents moderate overall malpractice risk and yields a heavy burden in finance and time. Key areas of relatively high litigation occurrence include missed acute myocardial infarction, missed fractures/foreign bodies, abdominal pain/appendicitis, wounds, intracranial bleeding, aortic aneurysm, and pediatric meningitis. Mitigation of risk is best accomplished through constructive communication, intelligent documentation, utilization of clinical practice guidelines and generalizable diagnoses, careful management of discharge against medical advice, and establishing follow-up for diagnostic studies ordered while in the ED (especially x-ray studies). Communication breakdown seems to be more predictive of malpractice litigation than injury experienced.Conclusions: There are consistent diagnoses that are associated with increased litigation incidence. A combination of mitigation approaches may assist providers in mitigation of malpractice risk. [ABSTRACT FROM AUTHOR]
