Introduction: Peripheral Vascular Disease (PVD) is a major cause of morbidity and is associated with Coronary Artery Disease (CAD). We aimed to perform Lower Limb Perfusion Scan (LLPS) in patients referred for Myocardial Perfusion Imaging (MPI) and estimate prevalence of PVD in subgroups with normal and abnormal MPI results. We also compared quantitative indices of LLPS in pati...

BACKGROUND Right ventricular dysfunction has been observed in uremic patients receiving percutaneous transluminal angioplasty (PTA). This prospective study focuses on the impact of tissue Doppler imaging echocardiographic parameters on assessing right ventricle function in uremic patients post PTA of dysfunctional hemodialysis access. METHODS Sixty uremic patients were divided into two groups...

Objective: The ankle-brachial index (ABI) as a simple test which can detect peripheral arterial disease (PAD). Therefore in this study we try to evaluate the diagnostic value of ABI for silent myocardial ischemia in diabetic patients and compare the results with myocardial perfusion imaging (MPI) results. Materials and Methods: All 149 diabetic patients in this study were categorized according...

BACKGROUND To point out a possible correlation between left atrial volume index (LAVI) and left ventricular (LV) diastolic time interval to better define LV diastolic dysfunction, this study was performed. METHODS In 62 hypertensive-hypertrophic patients without LV systolic dysfunction, LV volumes, myocardial mass index, ejection fraction% (EF%) and LAVI were measured by two-dimensional echoc...

introduction: this study evaluated the diagnostic value of the dipyridamole induced electrocardiuogram (ecg) cahnges, comparing with myocardial perfusion imaging. materials and methods: 222 patinets were studied with dipyridamole infusion (based on ecg criteria) as well as dipyridamole-myocardial perfusion imaging (mpi). results: abnormal dipyridamole test and abnormal mpi were noted in 11% and...

OBJECTIVE To evaluate the reproducibility of first-pass contrast-enhanced cardiac MR (CMR) myocardial perfusion imaging in patients with non-ischaemic dilated cardiomyopathy (NIDCM). DESIGN Prospective observational study. SETTING Single centre, tertiary care hospital. PARTICIPANTS 6 outpatient participants with NIDCM. OUTCOME Reproducibility of semiquantitative myocardial perfusion ana...

OBJECTIVE To evaluate left and right ventricular functions using tissue Doppler echocardiography (TDE) and myocardial performance index (MPI) methods in patients with slow coronary flow (SCF) and to determine the relationship between these parameters and thrombolysis in myocardial infarction frame count in SCF patients. SUBJECTS AND METHODS Thirty-five patients (20 males and 15 females) with ...

The fetal modified myocardial performance index (Mod-MPI) is a noninvasive, pulsed-wave Doppler-derived measure of global myocardial function. This review assesses the progress in technical refinements of its measurement and the potential for automation to be the crucial next step. The Mod-MPI is a ratio of isovolumetric to ejection time cardiac time intervals, and the potential for the left ve...

BACKGROUND Bronchopulmonary dysplasia (BPD) may result in chronic pulmonary artery hypertension and right ventricular (RV) dysfunction. Various echocardiographic assessments of RV dysfunction have been used to determine whether echocardiographic measurements of premature infants with BPD could provide sensitive measures of RV function that correlates with BPD severity. METHODS Twenty-eight co...
