Early mobilisation after coronary angiography to reduce back pain
BACKGROUND Coronary heart disease accounts for over 25,000 inpatient admissions and nearly 4,000 day-case admissions in New Zealand per year (Hay, 2004). Cardiac catheterization, via the femoral artery, is a common procedure undertaken to assess for and treat coronary heart disease (Chair, Li and …

Detection and prediction of cardiac quiescence for computed tomography coronary angiography
… reduce the radiation dose of computed tomography coronary angiography (CTCA) imaging by developing gating techniques based on signals derived from cardiac motion, rather than the currently used electrocardiogram (ECG), to more reliably trigger data acquisition during periods of cardiac quiescence. …

Improving Cardiovascular Risk Assessment with CT Coronary Angiography and Myocardial CT Perfusion
Accurate assessments of coronary atherosclerosis, calcification and myocardial perfusion are necessary to determine future cardiovascular risk in various clinical settings. CT coronary angiography (CTCA) and myocardial CT perfusion (CTP) are promising techniques for the assessment of these factors. …

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 …

Optimizing registration of complex vascular geometries
Advances in imaging, such as coronary angiography, intravascular ultrasound, and optical coherence tomography, can improve procedural success and outcomes for endovascular catheter intervention, such as stent implantation. Yet, these imaging modalities are not universally embraced; and thus, …

Cardiac Co-morbidities in Chronic Obstructive Pulmonary Disease
BACKGROUND: Coronary artery disease (CAD) is a frequent co-morbidity in chronic obstructive pulmonary disease (COPD) and cardiovascular disease is the most common cause of death in COPD. Therefore, this study was performed to identify the prognostic factors associated with the CAD in COPD and …
