Background: Advanced critical care echocardiography comprises a specific set of qualitative and quantitative point-of-care echocardiography skills, including a reliable, noninvasive method to measure cardiac output. This technique requires echocardiographic measurement of left ventricular outflow tract (LVOT) diameter and LVOT velocity time integral (VTI). Although there is a demand among critical care fellows to learn these advanced techniques, there are no data describing the acquisition of mastery in these skills.

We investigated the impact of trimetazidine treatment on left ventricular (LV) functions and cardiac biomarkers in diabetic patients with diastolic dysfunction as an early stage of diabetic cardiomyopathy. Sixty-three patients were randomly assigned to receive either trimetazidine or a placebo for 3 months. At baseline and after 3-months of treatment, measurements of serum levels of glycemic control parameters, lipid profile, tumor necrosis factor alpha, transforming growth factor beta 1, n-terminal pro brain natriuretic peptide and assessment of modified Medical Research Council (mMRC) dyspnea score, echocardiographic indices of LV functions and LV global longitudinal strain (GLS) were performed.

Cardiac wall motion abnormalities (WMA) are strong predictors of mortality, but current screening methods using Q waves from electrocardiograms (ECGs) have limited accuracy and vary across racial and ethnic groups. This study aimed to identify novel ECG features using deep learning to enhance WMA detection, referencing echocardiography as the gold standard. We collected ECG and echocardiogram data from 35,210 patients in California and labeled WMA using unstructured language parsing of echocardiographic reports.

Echocardiographic Z-score models play a crucial role in defining cardiac pathology in paediatric patients. There are multiple models that practitioners utilize in the United States without guiding principles to standardize their use. Discrepant interpretations can occur depending on the model chosen, even if standardized Z-score cutoffs are applied.
