Journal of clinical ultrasound : JCU.J Clin Ultrasound.2016 Nov 12;44(9):555-560. doi: 10.1002/jcu.22376. Epub 2016 Jul 14.
PURPOSE: Myocardial contractile reserve is associated with clinical prognosis in patients with dilated cardiomyopathy (DCM). We assessed myocardial contractile reserve using tissue Doppler strain rate imaging with dobutamine stress echocardiography in DCM patients.METHODS: Simultaneous echocardiogra

The detection of viable myocardium by low-dose dobutamine stress speckle tracking echocardiography in patients with old myocardial infarction.

Li L1, Wang F2, Xu T3, Chen J2, Wang C2, Wang X2, Li D4.
Journal of clinical ultrasound : JCU.J Clin Ultrasound.2016 Nov 12;44(9):545-554. doi: 10.1002/jcu.22366. Epub 2016 May 7.
PURPOSE: To explore the significance and value of speckle-tracking echocardiography (STE) associated with low-dose dobutamine stress echocardiography (LDDSE) for the detection of viable myocardium (VM) in patients with old myocardial infarction (OMI).METHODS: We performed STE with LDDSE in 33 hospit

Clinical toxicology (Philadelphia, Pa.).Clin Toxicol (Phila).2016 Nov;54(9):881-885. Epub 2016 Jul 21.
OBJECTIVE: Acute beta-blocker overdose can cause severe cardiac dysfunction. Chronic toxicity is rare but potentially severe. We report therapeutic dosing of metoprolol resulting in unusual pharmacokinetics and toxicity, given high-dose insulin therapy for treatment.CASE DETAILS: A 90-year-old femal
