CT coronary angiography can safely exclude significant coronary artery disease in patients undergoing valve and aorta surgery

Many patients needing isolated valve and ascending aorta surgery undergo invasive coronary angiography (ICA) to exclude significant coronary artery disease (CAD). CT coronary angiography (CTCA) could evaluate the coronary arteries in this population without the risks of an invasive procedure.

Can significant coronary artery disease be ruled out by CT coronary angiography in patients weighing greater than 100 kg?

The investigation of chest pain in overweight patients (>100 kg) can be challenging due to limited exercise capacity and suboptimal imaging. CT coronary angiography (CTCA) is an appropriate investigation for chest pain syndrome (CPS) and we sought to determine the effectiveness of CTCA in overweight patients.

The development of a structured and cohesive service for people admitted to hospital with a diagnosis of heart failure. The 20,000 days campaign

Heart failure is a challenging condition to treat, requires a team effort and is most effective if the patient understands their condition and engages in self-care measures that reduce the impact of the condition. However, local audit identified inconsistent implementation of guideline based management, lack of self-management support and insufficient specialist resource.

“Normal” coronary arteries in the setting of acute coronary syndrome: Frequency and outcomes

A proportion of patients presenting with acute coronary syndrome (ACS) are found to have non-obstructive coronary disease on angiography. We investigated the frequency and impact of this finding in our ACS population.

An audit of EP procedures and complications

The number of patients undergoing Electrophysiology (EP) procedures in New Zealand is increasing. This audit looks at the type of procedures performed, success rates and complication rates. Demographic data has also been gathered.

“Murmur clinic” – A novel use of cardiology resources to address an unmet need

Currently asymptomatic murmurs heard by General Practitioners (GP’s) are not meeting threshold for review by Cardiologists as per Ministry of Health guidelines. Anecdotal experience showed that we were missing a significant number of patients with serious pathology, by relying heavily on the clinical acumen of GP’s to distinguish the pathological from the physiological murmur. The decision was therefore made to set up a Murmur clinic to review patients with asymptomatic murmurs and to audit results to determine whether murmur clinic is an appropriate utilisation of resource.

Fulminant myocarditis

Fulminant myocarditis is a rare condition with acute onset, rapid clinical deterioration and cardiogenic shock. We identified all adult patients with fulminant myocarditis referred to our institution over an eleven-year period and describe their initial management and clinical outcomes.

Outcomes of structural interventions in a hospital without onsite cardiothoracic surgery

Structural interventions are commonly performed in eligible patients. Short term and long term complications in regional hospitals without onsite cardiothoracic surgery have never been reviewed.

Pathological autophagy augments cell death in the diabetic heart

Diabetic heart disease (DHD) is one of the major causes of mortality and morbidity in people with diabetes. DHD is characterised by the excessive loss of cardiovascular cells including cardiac stem cells. However, the exact mechanism leading to this loss remains unknown. Autophagy is a cellular degradation pathway that plays an important role in cellular homeostasis which becomes pathological when the balance is lost. Our recent studies conducted using mouse model of type-2 diabetes showed pathological autophagy in the diabetic heart.

Regional transfer; How much do patients know?

The transfer of patients with acute cardiac conditions to tertiary centres for clinical care is not associated with a system that returns patients to their home district health board (DHB) following care. Uncertainty about return transport can contribute to patient anxiety at an already stressful time. We examined patients understanding of transport arrangements before and after introduction of a pamphlet explaining transport options.
