Myocardial Function after Coronary Artery Bypass Grafting in Patients with Preoperative Preserved Left Ventricular Ejection Fraction-The Role of the Left Ventricular Longitudinal Strain.

: The role of coronary artery bypass grafting (CABG) on postoperative left ventricular (LV) function in patients with preoperatively preserved left ventricular ejection fraction (LVEF) is still being discussed and only a few studies address this question. This study aimed to assess LV function after CABG in patients with preoperatively preserved LVEF using left ventricular longitudinal strain assessed by 2D speckle tracking imaging (STI). : Fifty-nine consecutive adult patients with coronary artery disease (CAD) referred for a first-time elective CABG surgery were enrolled in the final analysis of this prospective single-center clinical study.

Frequency of Left Atrial Enlargement According to Different Modes of Indexing in Overweight and Obese Individuals.

: Current guidelines recommend indexing left atrial volume (LAV) by body surface area (BSA). However, in overweight and obese individuals this may result in the underestimation of left atrial enlargement (LAE). The aim of our study was to assess whether alternative LAV indexing to height and/or height-squared better identifies individuals with LAE among those who are overweight and/or obese.

Predictors of Spontaneous Echo Contrast in Left Heart Chambers in Patients with Dilated Cardiomyopathy: Slowing Down Might not Always Mean Enjoying Life.

Introduction: Spontaneous echo contrast(SEC) is usually detected in heart chambers as a result of reduced flow velocity in the cavity. The clinical importance of SEC lies in its association with embolic events. The aim of our study was to determine the frequency of SEC in left heart chambers in sinus rhythm patients with dilated cardiomyopathy and predictors for its emergence.

Changes of Left Ventricular Systolic Function in Patients Undergoing Coronary Artery Bypass Grafting.

Aim: This prospective study was designed to evaluate the changes in left ventricular (LV) systolic function after coronary artery bypass grafting (CABG) in patients with both normal and abnormal pre-operative systolic function.

Methods: During the period from October 2017 to October 2018, forty-seven consecutive patients undergoing CABG were enrolled in this prospective study. Transthoracic echocardiography was performed within 1 week before CABG as well as 4 to 6 months after surgery.

Uric acid and left ventricular hypertrophy: another relationship in hemodialysis patients.

Background: The impact of serum uric acid (UA) on morbidity and mortality in hemodialysis (HD) patients is quite controversial in relation to the general population. The aim of this study was to evaluate the association of serum UA with both mortality and left ventricular hypertrophy (LVH) in HD patients.

Methods: This longitudinal study enrolled 225 prevalent HD patients who were classified into three groups according to their follow-up-averaged UA (FA-UA) levels: low FA-UA (FA-UA <400 µmol/L), intermediate/reference FA-UA (FA-UA between 400 and 450 µmol/L) and high FA-UA (FA-UA >450 µmol/L).
