Coronary Reactive Hyperemia
… ADP could play a vital role in the mechanism of coronary post ischemic reactive hyperemia and that increased concentrations of plasma ADP could also stimulate a negative feed back loop governing release of ATP from red blood cells as well as an increased release of t-PA. It was also hypothesized …

Clinical outcome and Predictive factors of Coronary aneurysm after Percutaneous Coronary Intervention
Coronary artery aneurysms (CAAs) defined as angiographic luminal dilatation (50% larger than the adjacent reference vessel) at the site of stent implantation are rare and the reported incidence varies from 0.3% to 6%(Aoki et al., 2008). A new term, peri-stent contrast staining (PSS) was defined as …

Predicting Obstructive Coronary Artery Disease in Patients Undergoing Coronary Angiography for Stable Angina
… the pre-test probability of obstructive coronary artery disease (CAD) in patients presenting with chest pain is key in determining the next steps in management. The Diamond-Forrester model, or an updated version, are currently recommended to calculate a patient’s pre-test probability of …

Health-related Quality of Life One Year After Coronary Angioplasty and/or Coronary Stenting
… than 950,000 deaths were attributed to CVD with coronary artery disease comprising 50% of the deaths (American Heart Association, 1997). Percutaneous transluminal coronary angioplasty (angioplasty) and coronary stenting (stenting) are common revascularization treatments for coronary artery …

Computational model of coronary tortuosity
Coronary tortuosity is the abnormal curving and twisting of the coronary arteries. Although the phenomenon of coronary tortuosity is frequently encountered by cardiologists its clinical significance is unclear. It is known that coronary tortuosity has significant influence on the hemodynamics …

Impact of family history of premature coronary disease on carotid ultrasound and coronary calcium findings
… relatives (FDRs) of subjects with early onset of coronary heart disease (CHD) have higher risk of developing cardiovascular disease. We verified early CHD by angiography in the index patients and extensively phenotyped their FDRs to investigate the relationship of traditional and non-traditional …

Coronary flow mechanics: an anatomically based mathematical model of coronary blood flow coupled to cardiac contraction
Coronary blood flow through the ventricular contraction cycle has been investigated in this thesis using an anatomically accurate computational model. Using Strahler ordered morphological data and an avoidance algorithm a three dimensional finite element model has been constructed of the largest …

Automated stenosis quantification in coronary arteriograms
… the diameter and cross-sectional area of coronary artery lesions. In this study, two different strategies are employed for identification of artery contours, i.e., scanning and tracKing The scanning approach is accomplished by a canny edge detector. The edge tracking approach is in favor …

Personality predictors of coronary heart disease
Fifty percent of the diagnosed cases of coronary heart disease in the United States are of unknown etiology. This study proposed that five personality traits— achievement, dominance, aggression, succorance and Critical Parent—differentiate individuals with coronary heart disease manifestations. The …

Genotype- versus phenotype-directed personalization of antiplatelet treatment in Koreans with coronary artery disease undergoing coronary stenting
… Sixty-five patients undergoing percutaneous coronary intervention for non-ST elevation acute coronary syndromes were randomly assigned to genotype- or phenotype-directed treatment. All patients were screened for the CYP2C19 *2, *3, or *17 alleles by using Verigene CLO assay (Nanosphere, …

A study on the short-term cognitive outcome of percutaneous transluminal coronary angioplasty with intra-coronary stenting
… cognitive outcome of percutaneous transluminalcoronary angioplasty with intra-coronary stenting. Participants were assessed cognitively using specific neuropsychological tests used to measure performance in the seven cognitive domains. Forty people took part in the study, with twenty of them …

Polo-Like Kinase 1 and Smooth Muscle Cells in Coronary Artery Bypass Conduits and Coronary Arteries Following Angioplasty
… in SMCs, following percutaneous transluminal coronary angioplasty (PTCA) and coronary artery bypass grafting that may contribute to greater SMC proliferation in the injured versus uninjured blood vessels in swine.|Approach and Results — At the basal level, higher expression of PLK1 and pPLK1 …

Bioactive surfaces for improved coronary stent performance
… eluting stents (DES) are widely used to treat coronary heart disease. Although current DES generally perform well, restenosis and delayed endothelium healing still remains an issue following stent implantations. Research efforts are now focused on the development of stent coatings that address …

Magnetic Resonance Imaging in Paediatric Coronary Vasculopathy
Background Coronary Allograft Vasculopathy (CAV) is the leading cause of late death for children after heart transplantation. It often presents late due to lack of ischaemic symptoms from the denervated allograft and it is difficult to detect using conventional angiography. A non-invasive …

Metabolic and endocrine aspects of coronary disease
… early history, the nature and the incidence of coronary atherosclerosis and ischaemic heart disease have been reviewed. Evidence has been presented to suggest that there are aetiological factors which favour the development of ischaemic heart disease without influencing the incidence of coronary …

Computer Modelling Informed Coronary Artery Bypass Grafting
Coronary artery disease is the leading cause of mortality and morbidity worldwide. Coronary artery bypass grafting operations have been performed as a treatment for this disease for over 60 years. There has been recent interest in the exclusive use of arterial grafts as conduits for this operation, …

The effects of preconditioning coronary artery disease patients with hyperbaric oxygen prior to coronary artery bypass graft surgery & cardiopulmonary bypass
IntroductionCoronary artery bypass graft (CABG) is associated with periods of ischaemia and reperfusion, which may lead to myocardial dysfunction. In clinical studies, hyperbaric oxygen (HBO2) treatment following an acute myocardial infarction (AMI), has been shown to limit myocardial injury and …
