Echocardiographic strain imaging, also known as deformation imaging, has been developed
as a means to objectively quantify regional myocardial function. First introduced as post …

Chronic heart failure continues to impose a substantial health-care burden, despite recent
treatment advances. The key pathophysiological process that ultimately leads to chronic …

Background Cardiac-resynchronization therapy (CRT) reduces morbidity and mortality in
chronic systolic heart failure with a wide QRS complex. Mechanical dyssynchrony also …

Background—Cardiac resynchronization therapy improves mortality and morbidity in
patients with heart failure (HF) with wide QRS complex and diminished left ventricular (LV) …

Abstract Aims Apical rocking (ApRock) and septal flash (SF) are often observed phenomena
in asynchronously contracting ventricles. We investigated the relationship of visually …

Background Cardiac resynchronization therapy (CRT) is effective in reducing clinical events
in patients with heart failure and prolonged QRS interval. Studies using surrogate measures …

Background Left ventricular (LV) ejection fraction (EF) is a routine clinical standard to assess
cardiac function. Global longitudinal strain (GLS) and global circumferential strain (GCS) …

Background: Left bundle branch pacing (LBBP) has emerged as an alternative to
biventricular pacing (BVP) for delivering cardiac resynchronization therapy. We sought to …

Background: Current guidelines suggest that patients with left bundle branch block (LBBB)
be treated with cardiac resynchronization therapy (CRT); however, one-third do not have a …

Background It is known that measuring the triglyceride glucose (TyG) index and TyG-related
parameters [triglyceride glucose-body mass index (TyG-BMI), triglyceride glucose-waist …
