Lung volume reduction surgery : the Groote Schuur experience
… fourth most common cause of death in USA after myocardial infarctions, cancer and stroke (91). COPD is clearly under diagnosed in the early stages (101). Early smoking cessation would have an enormous impact on the progression of the disease (7,24,25,58,106).

Association of adverse cardiovascular outcomes with weighted morphologic variability following non-ST-elevation acute coronary syndromes
… patients at an increased risk of recurrent myocardial infarctions and cardiovascular death. In this work, we develop a new ECG-based measure for patient risk stratification called weighted morphologic variability. This measure is based on assessment of beat-to-beat changes in the morphology …

Influence of Oxygenated Perfluorocarbon (oxyPFC) on survival and free radical production of Ischemic Cardiomyocytes
… route have the potential to reduce the size of myocardial infarctions. The exact mechanism by which this reduction occurred remained unclear until today. The subject of this experimental work was to elucidate the pathways of interaction of oxyPFC with hypoxic cardiomyocytes. The first mechanism …

Heart rate variability in mice with coronary heart disease
… the risk of mortality in patients after an acute myocardial infarction. Recently, the Krieger lab at MIT developed genetically engineered double knockout (dKO) mice that develop coronary artery disease accompanied by spontaneous myocardial infarctions and die at a very young age. This thesis …

Predictors of Neuropsychological Status in Cardiac Patients
… the majority of cases, and are responsible for Myocardial Infarctions (MI), Coronary Artery Bypass Grafting (CABG) surgery, and other common disease sequelae and treatment paradigms. While the fact that heart can negatively impact cognitive functioning is well documented, the factors that drive …

Patterns of heart attacks
Myocardial infarction is a derivative of heart disease that is a growing concern in the United States today. With heart disease becoming increasingly predominant, it is important to not only take steps toward preventing myocardial infarction, but also towards predicting future myocardial …

Cost-effectiveness analysis of alternative statin prescribing strategies for the secondary prevention of cardiovascular disease at a South African public sector tertiary hospital
… reduce the risk of cardiovascular events such as myocardial infarctions and strokes, by lowering low density lipoprotein cholesterol (LDL-C) concentrations. Several studies, mostly conducted in Europe or North America, have demonstrated that statins are cost effective, particularly when used to …

Development of in vivo Raman spectroscopy of atherosclerosis
… whose rupture accounts for the majority of myocardial infarctions. By studying the distribution of Raman light in tissue, we have designed, constructed, and tested small diameter, high throughput optical fiber Raman probes which employ a modular micro-optical filter configuration to remove …

Analysis of Cartesian and projection (K,T)-space sampling patterns when using the partially separable functions model for cardiac perfusion MR imaging
… perfusion imaging is used to diagnose ischemic myocardial tissue, coronary artery disease, and, to a lesser extent, myocardial infarctions. To diagnose these tissues and diseases, real time ECG triggered cardiac imaging techniques (fast T1-weighted gradient echo, echo planar, or steady-state …

Artificial neural networks for cardiovascular risk, cardiovascular fitness and ankle-brachial index
… and the relative risk stratum for future myocardial infarctions or stroke as output. For the Ankle-Brachial Index and the cardiovascular fitness networks, data was obtained from the National Health and Nutrition Examination Survey. The network for cardiovascular fitness was compared with …

Spatial analysis of ischemic heart disease in Manitoba
… were to: (1) detect geographic clusters of acute myocardial infarctions (AMI) within Manitoba; (2) assess whether IHD is related to the geographic distribution of some its well-known risk factors; and (3) what relationship IHD has to the temporal dimension throughout geographic space. Methods: The …

Peptide targeted imaging of neutrophil invasion in cardiac tissue
… interaction. In addition, we developed a myocardial infarction and reperfusion model to pair visualization of peptide bonding with functional studies that test the beneficial effect. In this way we can correlate the amount of neutrophil blocking necessary to significantly improve heart …

The Use of Hair Cortisol as a Biomarker of Chronic Stress in Patients with a recent Acute Myocardial Infarction
Background Acute Myocardial infarction (MI) or heart attack is a leading cause of death worldwide. Since an MI is a stressful life event, plasma cortisol levels are expected to increase significantly from the baseline. Cortisol and dehydroepiandrosterone (DHEA) as products of the …

The assessment of biomechanical modelling and PET/MR imaging in coronary atherosclerosis
… post-mortem studies showed that only 14% of myocardial infarctions (MIs) were caused by plaques with >70% stenosis. Plaque vulnerability, characterised by morphological and compositional features, is more important than the luminal stenosis measurements. Mini-invasive virtual-histology …

Computational modelling of hydrogel therapies
Myocardial infarctions (heart attacks) are a type of cardiovascular disease that affects a large population of people around the world. They lead to the death of heart tissue, which is eventually replaced by scar tissue in a non-reversible process. Scar tissue does not behave like normal heart …

The use of biomaterials for stem cell therapies to prevent myocardial damage post-infarct
… the surface of damaged heart tissue following a myocardial infarction. While current medical practices to address the immediate aftermath of a myocardial infarction (MI) have evolved tremendously, there are few, if any, techniques currently administered to slow, cease, or reverse the negative …

Computer Modeling of Cardiac Electrical Activity by Polarcardiogram Patterns
… (b) analyzing Dr. Gordon Dower’s criteria for myocardial infarction using the programs provided in this thesis.</p> <p>The problem inherent in the reading of a polarcardiogram is the identification of the "loop" patterns with the associated heart disease. This can be accomplished by reading and …
