Evaluation of the relationship between COVID-19 pneumonia severity and pulmonary artery diameter measurement.

The goal of the present work was to examine associations between COVID-19 pneumonia severity and pulmonary artery diameter. A total of 101 patients with COVID-19 were included in this retrospective observational study. The patients were divided into three groups based on the CT images: 41 patients with mild pneumonia, group 2 had 39 patients with moderate pneumonia, and group 3 had 21 patients with severe pneumonia.

Increased Arterial Stiffness Measured By Carotid Femoral (Aortic) Pulse Wave Velocity In Patients with Inactive Behçet's Disease.

Introduction Behçet's disease (BD) is a chronic, multisystemic disease characterised by vascular involvement. Acute and chronic inflammatory processes associated with BD may cause endothelial dysfunction, which can then lead to a subsequent increase of arterial stiffness and altered pressure wave reflections. The aim of this study was to evaluate the pulse wave velocity (PWV) measurements in patients with inactive BD and control subjects.

The frequency of type 2 second-degree and third-degree atrioventricular block induced by blunt chest trauma in the emergency department: A multicenter study.

Background: Conduction disturbances including type 2 second-degree atrioventricular block (Mobitz II) and third-degree atrioventricular block following blunt chest trauma are probably rare. Moreover, the pathophysiological mechanisms responsible for this rare dysrhythmia following trauma are not well understood yet. In this study, it was aimed to identify the frequency of this dysrhythmia associated with trauma.

Acute effects of ultrafiltration on aortic mechanical properties determined by measurement of pulse wave velocity and pulse propagation time in hemodialysis patients.

Objective: The effects of acute hemodialysis session on pulse wave velocity are conflicting. The aim of the current study was to assess the acute effects of ultrafiltration on the aortic mechanical properties using carotid-femoral (aortic) pulse wave velocity and pulse propagation time.

Methods: A total of 26 (12 women, 14 men) consecutive patients on maintenance hemodialysis (mean dialysis duration: 40.

The effects of serum potassium and magnesium levels in a patient with Gitelman's syndrome on the timing of ventricular wall motion and the pattern of ventricular strain and torsion.

Gitelman's syndrome is a primary renal tubular hypokalemic metabolic alkalosis. Hypokalemia and hypomagnesemia can cause cardiac tissue excitability and conduction. Global ventricular mechanical function is directly related to the contractile properties of cardiac myocytes, which are largely dependent on the flow of ions such as potassium and magnesium.
