Comparative StudyLong-term prognosis and outcome in patients with a chest pain syndrome and myocardial bridging: a 64-slice coronary computed tomography angiography study.
Small case series have associated coronary myocardial bridging (MB) with adverse cardiac events. However, the clinical significance of MB in unselected patients with chest pain remains unclear. The purpose of this study was to explore the relation between the presence of isolated MB and subsequent adverse cardiac events in symptomatic patients referred for coronary computed tomography angiography (CCTA). ⋯ MB is a common finding on CCTA among patients presenting with chest pain but no obstructive CAD. No association was evident between MB and the risk of CV death or MI.

Left ventricular twist in a normal African adult population.
Speckle tracking has emerged as a quantitative technique for assessing left ventricular (LV) function. However, no normative data for LV twist using speckle tracking echocardiography (STE) are available in the black population. This study assessed myocardial mechanics by determining LV twist parameters in different age groups using STE, and evaluated the effect of ageing on LV twist in this population. ⋯ These data establish values for strain and twist in a normal black adult population. Net twist increases with age, whereas strain parameters decrease. Age is the strongest independent predictor of LV twist.

Comparative StudySite-dependency of the E/e' ratio in predicting invasive left ventricular filling pressure in patients with suspected or ascertained coronary artery disease.
To test the accuracy of different mitral annular sites of the E/e' ratio in predicting invasive left ventricular filling pressure (LVFP) in patients hospitalized for coronary artery disease (CAD). ⋯ In patients with CAD, E/e'L is the most accurate parameter in predicting abnormally increased LVFP.

Comparative StudyLeft atrial strain and strain rate before and following restrictive annuloplasty for ischaemic mitral regurgitation evaluated by two-dimensional speckle tracking echocardiography.
We retrospectively evaluated left atrial (LA) strain and strain rate (SR) before and after undersized mitral ring annuloplasty (UMRA) for chronic ischaemic mitral regurgitation (CIMR) with two-dimensional speckle-tracking echocardiography. ⋯ Left atrial peak global strain, peak systolic SR, and peak early diastolic SR were cofactors associated to recurrent MR. The assessment of LA strain and SR, in addition to other echocardiographic parameters, can be helpful in detecting patients undergoing UMRA who are unlikely to benefit from annuloplasty.
