Background: Cardiac involvement and the consequences of inflammation induced by SARS-CoV2 infection could have catastrophic long-term consequences. Left ventricular mechanics could identify a specific pattern of myocardial fiber damage in patients infected with COVID-19. To our knowledge there are no publications referring to the global description of ventricular mechanics in patients with COVID-19. Objective: To describe left ventricular mechanics in hospitalized patients with COVID-19. Methods: In this cross-sectional study, we included 40 hospitalized patients with confirmed diagnostic of COVID-19, from April 11, 2020, to September 6, 2020. Demographic and laboratory data, clinical and echocardiographic characteristics were collected, as well as events during hospitalization. Left ventricular deformation was analyzed and reported. Results: Subclinical dysfunction was observed in 82.5% (left ventricular longitudinal strain [LVGLS] -17.05% and global circumferential strain [GCS] -18.6%) of the patients, likewise, the mean twist and apical rotation were preserved, and even increased as part of the compensating mechanism to maintain the ejection fraction. Conclusion: In patients hospitalized with COVID-19, despite having a normal left ventricular ejection fraction, subclinical myocardial damage was found, manifested by a decrease in Global Longitudinal Strain (GLS) and Global Circumferential Strain (GCS). This behavior is similar to that of cardiomyopathies in the early stage of the disease, and given the pathophysiological mechanisms involved in the disease, its long-term consequences should be monitored and evaluated.

Atrial fibrillation in the elderly： predisposing factors and management

引用

Journal of Geriatric Cardiology 2017年第3期14卷 185-194页

作者： Juan Lacalzada-Almeida Javier Garcia-Niebla Department of Cardiology Hospztal Umversitarlo de Canarias Tenerife Spain Servicios Sanitarios del Area de Salud de El Hierro Valle del Golfo Health Center El Hierro Spain

In the last twenty years, new imaging techniques to assess atrial function and to predict the risk of recurrence of atrial fibrillation after treatment have been developed. The present review deals with the role of these techniques in the detection of structural and functional changes of the atrium and diagnosis of atrial remodeling, particularly atrial fibrosis. echocardiography allows the detection of anatomical, functional changes and deformation of the atrial wall during the phases of the cardiac cycle. For this, adequate acquisition of atrial images is necessary using speckle tracking imaging and interpretation of the resulting strain and strain rate curves. This allows to predict new-onset atrial fibrillation and recurrences. Its main limitations are inter-observer variability, the existence of different software manufacturers, and the fact that the software used were originally developed for the evaluation of the ventricular function and are now applied to the atria. Cardiac magnetic resonance, using contrast enhancement with gadolinium, plays a key role in the visualization and quantification of atrial fibrosis. This is the established method for in vivo visualization of myocardial fibrotic tissue. The non-invasive evaluation of atrial fibrosis is associ- ated with the risk of recurrence of atrial fibrillation and with electro-anatomical endocardial mapping. We discuss the limitations of these techniques, derived from the difficulty of demonstrating the correlation between fibrosis imaging and histology, and poor intra- and inter- observer reproducibility. The sources of discordance are described, mainly due to image acquisition and processing, and the challenges ahead in an attempt to eliminate differences between operators.

Background: Atrial fibrillation (AF) is the most common cardiac arrhythmia. It increases cardiovascular morbidity, especially embolic stroke and mortality. Two-dimensional speckle tracking echocardiography (2D STE) is a useful method that has been used to detect changes in atrial myocardial deformation in AF patients. Objectives: To study atrial myocardial deformation changes in patient with non-valvular AF using 2D STE. Patients and Methods: This study included 25 patients with non-valvular AF and 25 normal healthy controls. 2D STE was used for assessment of strain and strain rate of septal and free walls of both right atrium (RA) and LA and left ventricle (LV). Results: Mean LA septal and lateral strain and strain rate were significantly reduced in the AF group compared to the control group (-7.2% ± 5.2% vs. -20.4% ± 3.9%, -8.7% ± 8.8% vs. -21.7% ± 3.4%) and (-0.9 ± 0.5 S-1 vs. -1.9 ± 0.4 S-1, –1.1 ± 0.6 S-1 vs. -2.04 ± 0.3 S-1) respectively. Mean RA septal and lateral strain and strain rate were significantly reduced in the AF group compared to the control group (-5.9% ± 6.1% vs. -23.4% ± 4.5%, -8.9% ± 9.3% vs. -21.7% ± 3.4%) and (-0.98 ± 0.6 S-1 vs. -1.9 ± 0.3 S-1, -1.3 ± 0.9 S-1 vs. -2.1 ± 0.5 S-1) respectively.
