Clinical features and major bleeding predictors for 161 fatal cases of COVID-19: A retrospective observational study.

The aim of this study was to investigate the patient characteristics and laboratory parameters for COVID-19 non-survivors as well as to find risk factors for major bleeding complications. For this retrospective study, the data of patients who died with COVID-19 in our intensive care unit were collected in the period of March 20 - April 30, 2020. D-dimer, platelet count, C-reactive protein (CRP), troponin, and international normalized ratio (INR) levels were recorded on the 1st, 5th, and 10th days of hospitalization in order to investigate the possible correlation of laboratory parameter changes with in-hospital events.

Prognostic significance of temporal changes of lipid profile in COVID-19 patients.

Background: COVID-19 is a multisystemic disease that affects many organs and has metabolic effects.

Aims: This study aims to investigate the effect of the temporal changes of lipid levels on the prognosis during the course of the disease.

Study Design: Retrospective cross-sectional study.

The effect of the severity COVID-19 infection on electrocardiography.

Objective: Acute myocardial damage is detected in a significant portion of patients with coronavirus 2019 disease (COVID-19) infection, with a reported prevalence of 7-28%. The aim of this study was to investigate the relationship between electrocardiographic findings and the indicators of the severity of COVID-19 detected on electrocardiography (ECG).

Methods: A total of 219 patients that were hospitalized due to COVID-19 between April 15 and May 5, 2020 were enrolled in this study.

Echocardiographic features of patients with COVID-19 infection: a cross-sectional study.

COVID-19 patients with cardiac involvement have a high mortality rate. The aim of this study was to investigate the echocardiographic features in COVID-19 patients between severe and non-severe groups. For this single-center study, data from patients who were treated for COVID-19 between March 25, 2020 and April 15, 2020 were collected.
