To evaluate the relationships between ST-segment resolution (STR) and echocardiography-determined left ventricular (LV) global and regional function and deformation in the sub-acute phase of STEMI. ⋯ STR correlated with global and regional LV function and deformation in patients with sub-acute phase of STEMI after PCI. RLS and GLS were the strongest correlates of STR at the regional and global levels, respectively.

Severe atrial structural remodeling may reflect irreversible damage of the atrial tissue in patients with atrial fibrillation (AF) and is associated with changes of P-wave duration and morphology. Our aim was to study whether variability of P-wave morphology (PMV) is associated with outcome in patients with AF after circumferential PV isolation (CPVI). ⋯ We report a significant association between increased PMV and 6-month CPVI success. PMV may help to identify patients with very high likelihood of freedom of AF 6-months after CPVI.
