background: the implications of cardiac risk stratification before orthotopic liver transplantation (olt) are not well established. we studied the usefulness of myocardial perfusion imaging (mpi) in this scenario. methods: mpi data of 24 patients (9 females), candidates of olt, were collected. they underwent mpi as part of their preoperative risk assessment. mpis were interpreted by 2 nuclear p...

OBJECTIVE To investigate whether the myocardial performance index (MPI) can predict left ventricular functional outcome in patients with early recanalisation after anterior acute myocardial infarction (MI) and to determine when the index should be measured. DESIGN MPI was measured serially by two dimensional Doppler echocardiography after successful percutaneous coronary intervention (PCI). L...

BACKGROUND The purpose of this study was to evaluate left and right ventricular functions by using the Doppler myocardial performance index (MPI), in children with sickle cell anemia (SCA). METHODS We examined 32 patients with SCA and 30 age-matched healthy children. Echocardiography and Doppler examinations were completed for each of the subjects. MPI was calculated from the Doppler tracings...

OBJECTIVE The study aimed to use myocardial perfusion imaging (MPI) as a semi-quantitative method to assess the clinical severity of pulmonary arterial hypertension (PAH) in patients with congenital heart disease (CHD). SUBJECTS AND METHODS A total of 24 patients with PAH related to CHD (PAH-CHD) who received interventional or medical treatment were included. All patients underwent physical e...

objective: the risk of cardiac death in diabetic patients is 3 times more than non-diabetics. but it is not determined who need cardiac screening. about 41% of diabetic patients with silent ischemia are missed. the carotid intima-media thickness (cimt) and ankel brachial index are two independent,simple and non invasive method in vascular complications diagnosis in diabetic patients.the aim of ...

Background We evaluated early and late pulmonary hypertension (PH) in preterm infants and its relation with bronchopulmonary dysplasia (BPD). Methods Sixty-seven preterm infants < 30 weeks' gestation underwent echocardiography within 14 days after birth for early PH and over 28 days after birth for late PH. We measured tricuspid regurgitation (TR) peak velocity, pulse Doppler-derived myocardi...

The aim of this study was to determine the feasibility and accuracy of wall motion score index (WMSI) and myocardial performance index (MPI) for measuring regional and global left ventricular (LV) function using high-resolution echocardiography after myocardial infarction (MI) in mice. 48 mice underwent MI by a mid-LAD ligation. Echocardiography was performed under anesthesia at baseline and on...
