Accurate localization of myocardial viability is important in diagnosis of infarction. Regional strain function provides excessive information for clinical decision making but comparison of strain tensor profiles across differing tissue types is usually difficult due to multi-variate nature of tensors. It is desirable to describe tensors with simplified scalar indices which are more mathematically...
Objective: Studies have shown that certain personality types (distressed personality-Type D) and Psychological Distress (anxiety/depression) is associated with Myocardial Infarction (MI) and has etiological and prognostic implications. Substantial research evidence has also suggested that Type D personality is significant predictor of post MI anxiety, depression and impaired quality of life. The present...
Functional regeneration of infarcted myocardium is still a big challenge in the therapy of cardiovascular diseases. In the present study, PDGF-BB gene therapy was investigated after myocardial infarction (MI) in rats. We found that the infarct size of male rats treated with PBS(control) group was 0.436plusmn0.128, while it was 0.280plusmn0.055 in the male rats of PDGF-BB gene transferred group. The...
Four-dimensional (4D), or equivalently, 3D + time, analysis is useful for comprehensive assessment cardiac function, especially in the asymmetric left ventricle (LV) after myocardial infarction (MI). This paper presents a 4D-model-based method for ultrasound assessment of cardiac contractile function in mice. Echocardiographic image sequences were acquired at high frequency (30 MHz) from the hearts...
Understanding heart regeneration in a vertebrate model system is a highly relevant public health concern. Coronary heart disease is among the leading causes of disability and mortality worldwide. Injured human hearts caused by myocardial infarction (MI) results in decreased cardiac performance and eventually the development of heart failure. In contrast to mammals, zebrafish fully regenerate myocardium...
Coronary heart disease (CHD) is a major cause of morbidity and mortality in the western world. Although significant progress has been made in the diagnosis and treatment of CHD, further investigation is still needed. The objective of this study was to develop a data mining system for the assessment of heart event related risk factors. The risk factors investigated were: i. clinical: sex, age, smoking,...
Magnetic resonance imaging (MRI) provides high spatial resolution, temporal resolution, and tissue contrast. It is ideally suited for the noninvasive assessment of cardiac structure and function. For routine cardiac patient management, functional assessment includes ventricular and valvular function, myocardial viability, perfusion, and metabolism. Highly desired but not yet available for managing...
Increasing evidence suggests that enhanced stimulation of the heart and kidney by mineralocorticoids plays significant role in development of the post-infarct cardiac failure. Because increased synthesis of mineralocorticoid receptors (MR) is one of the putative factors determining pathogenic effects of mineralocorticoids we decided to determine whether the myocardial infarct results in an enhanced...
