Evolution and Prognostic Impact of Left Ventricular Myocardial Work Indices After Transcatheter Aortic Valve Replacement in Patients With Severe Aortic Stenosis.

Purpose: Left ventricular myocardial work (LVMW) has been shown to better characterize LV function in patients with severe aortic stenosis by correcting LV afterload. The aim of this study was to evaluate the evolution in LVMW indices after transcatheter aortic valve replacement (TAVR) and their prognostic value.

Methods: The following LVMW indices were calculated before and immediately after TAVR in 255 patients (median age 82 years, 51% male): global work index (GWI), global constructive work (GCW), global wasted work (GWW) and global work efficiency (GWE).

Comparison of violence and aggressions suffered by health personnel during the COVID-19 pandemic in Argentina and the rest of Latin America.

Objectives.: Motivation for the study. The COVID-19 pandemic has caused profound repercussions at different socio-environmental levels.

[Self-perception of smoking cessation skills among Cardiology residents in Argentina].

Objective: To evaluate the self-perception of cardiology residents in Argentina regarding their abilities to help their patients stop smoking, as well as their opinions about their knowledge and skills in this area.

Materials And Methods: A cross-sectional study was carried out using secondary data from a study carried out in five Latin American countries and Spain, focusing on the information provided by cardiology residents in Argentina. Discrete variables were expressed as median and interquartile range, and categorical variables were expressed as percentages, and were analyzed using the chi-square test or Fisher's exact test, depending on the relative frequency of the expected values.
