Echocardiographic phase imaging to predict reverse remodeling after cardiac resynchronization therapy.
The aim of our study was to investigate whether echocardiographic phase imaging (EPI) can predict response in patients who are considered for cardiac resynchronization therapy (CRT). ⋯ Echocardiographic phase imaging can predict functional recovery, reverse LV remodeling, and clinical outcomes in patients who undergo CRT. EPI is a method that objectively and accurately quantifies LV dyssynchrony and seems to be noninferior to TDI for the prediction of reverse LV remodeling and functional recovery.

Abnormal glucose metabolism in acute myocardial infarction: influence on left ventricular function and prognosis.
We studied the influence of abnormal glucose metabolism on left ventricular (LV) function and prognosis in 203 patients with acute myocardial infarction. ⋯ Although perturbations in glucose metabolism were linearly associated with impairment of LV function in the early phase of acute myocardial infarction, this relationship alone did not explain the excess mortality in patients with newly detected or known diabetes.

Right atrial volume index in chronic systolic heart failure and prognosis.
The aim of this study was to determine the relationship between right atrial volume index (RAVI) and right ventricular (RV) systolic and diastolic function, as well as long-term prognosis in patients with chronic systolic heart failure (HF). ⋯ In patients with chronic systolic HF, RAVI is a determinant of right-sided systolic dysfunction. This quantitative and reproducible echocardiographic marker provides independent risk prediction of long-term adverse clinical events.

Comparative StudyIntraoperative fluorescence imaging system for on-site assessment of off-pump coronary artery bypass graft.
The aim of this study was to evaluate the intraoperative fluorescence imaging (IFI) system in the real-time assessment of graft patency during off-pump coronary artery bypass graft. ⋯ The IFI system enables on-site assessment of graft patency, providing both morphologic and functional information. This technique may help reduce procedure-related, early graft failures in off-pump bypass patients.
