Decreased left atrial strain parameters are correlated with prolonged total atrial conduction time in lone atrial fibrillation.

To investigate left atrium (LA) strain properties of patients with lone atrial fibrillation (LAF) and to assess relationships between LA strain parameters and total atrial conduction time measured with tissue Doppler imaging (PA-TDI). The study population consisted of 53 patients with LAF. The control group was comprised of 50 normal volunteers.

Relation of Hemoglobin A1c to myocardial acoustic densitometry and left ventricular diastolic function in patients with Type 2 diabetes mellitus and without evident heart disease.

Aim: The aim of the study was to detect the echocardiographic sensitive indexes for prediction of the subclinical cardiac dysfunction and to evaluate the relation between Hemoglobin A1c (HbA1c) and myocardial acoustic densitometry as well as cardiac function.

Methods: Fifty DM2 patients (48.5+/-8.
