Objective To assess the relationship between longitudinal changes in placental Doppler indices and maternal circulating angiogenic factors in the first half of pregnancy and delivery of a small-for-gestational-age (SGA) neonate, and ascertain whether longitudinal evaluation of these variables improves the prediction achieved by second-trimester cross-sectional evaluation. Methods From a prospec...
Background and purpose: Atrial fibrillation (AF) is a major cause of mortality and morbidity in patients after coronary artery bypass graft (CABG). Attempt for knowing indices and factor influence post CABG AF may help in finding patients at risk and prevent more complications. This study aimed to evaluate the association between diastolic dysfunction indices and grading with post CABG AF durin...
Background: Estimation of Left Ventricular End Diastolic Pressure (LVEDP) among patients with Mitral Stenosis (MS) helps to diagnose diastolic dysfunction and to explain their symptoms. However, Conventional Doppler measurements have limitation in predicting of LVEDP. This study sought to establish whether the correlation between measurements derived from Tissue Doppler echocardiography and LVE...
Introduction: In order to assess echocardiographic left ventricular functional indices in patients with differentiated thyroid carcinoma (DTC), after L-T4 withdrawal (short-term overt hypothyroidism) and during TSH suppressive therapy, we have evaluated cardiac hemodynamics in a single cohort study. Methods: 24 patients with DTC were studied in two phases: 1: at least 4 weeks after L-T4 withd...
