Background: Conventional echocardiography and tissue Doppler imaging have been highlighted to diagnose diastolic and systolic heart dysfunction. We aimed to compare tissue Doppler imaging with conventional echocardiography to diagnose heart dysfunctions in diabetes mellitus type 1 (DMT1) patients. <s...
Myocardial flow reserve (MFR) is not routinely assessed in myocardial perfusion imaging (MPI) studies but has been hypothesized to affect test accuracy when assessing disease severity by coronary vessel lumenography. Magnetic resonance imaging (MRI) is an emerging diagnostic technique that can both perform MPI and assess MFR. We studied women (n = 184) enrolled in the Women's Ischemia Syndrome ...
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 ...
Introduction : Patients with major thalassemia need recurrent transfusions and if not treated are at risk of heart dysfunction. Heart tissue could be abnormal in patients who use desferral continously due to iron deposits , fibrosis , hypertrophy and side effects of chronic anemia. Cardiac involvement is the main cause of morbidity and mortality in major thalassemics, so we decided to improve e...
AIMS Myocardial performance index (MPI), or Tei index, is a Doppler echocardiographic parameter defined as the sum of the isovolumic contraction and relaxation times divided by the ejection time. It is considered a reliable parameter for global left ventricular function. However, the interpretation of this index is not fully clear in diastolic dysfunction. We measured MPI in a pressure-overload...
BACKGROUND This study aimed to assess myocardial performance index (MPI) and arterial elasticity indices in asymptomatic patients with beta-thalassemia major without known heart disease and to determine relationship between these indices and parameters indicating iron load of body. METHODS The study included 55 asymptomatic beta-thalassemia patients (median age: 20 years (10 - 48 years)) with...
A 67 years old woman was referred to nuclear medicine center for myocardial perfusion imaging (MPI) for assessment of ischemic heart dieses (IHD).She had a history of atypical chest pain and dyspnea since about 10 days before admission. The MPI SPECT/CT was performed by stress/redistribution Tl-201 protocol. MPI was interpreted as relatively good coronary flow with no appreciable stress induced...
Introduction: We aimed to evaluate the relationship between coronary tortuosity and left ventricular relaxation disorder using conventional new diastolic function parameters evaluated with echocardiography. Methods: A total of 131 patients who underwent angiography for suspected artery disease were included in study. compared obtained echocardiography (CAT) normal arteries. Results: There was n...
