Long-term clinical outcome of patient with type I vs type II non-STEMI

Type I (myocardial necrosis from plaque disruption) and type II (myocardial from supply-demand mismatch) are most commonly encountered myocardial infarction (MI). It is unclear if this distinction has important implications on clinical outcome.

Clinical characteristics and outcomes of patients with P-associated cardiomyopathy (PAC) in Auckland, New Zealand

Methamphetamine or P-associated cardiomyopathy (PAC) is becoming an increasingly recognised entity. We aimed to describe the characteristics and outcome of patients with PAC presenting to Middlemore Hospital.

Cryoablation for AF in the Waikato; Early results

Cryoablation is a novel treatment for atrial fibrillation (AF). Commencing November 2012 with 3 operators (2 AF ablation novices), cryoablation has been performed in patients with paroxysmal AF and selected persistent AF cases. We retrospectively assessed all cryoablation patients treated over the first 14 months.

Percutaneous coronary intervention (PCI) outcomes at Tauranga Hospital: A new non-surgical centre’s early experience

Performance of PCI in New Zealand is largely restricted to hospitals in which cardiac surgery is performed. We started a non-surgical centre PCI program in April 2012, to address local needs for coronary revascularisation, with the support of the regional cardiac surgical centre. Safety and outcome data are presented.

Management of valvular heart disease: Role of echocardiography and assessment of pulmonary hypertension reversibility

Valvular heart disease (VHD) can lead to pulmonary hypertension (PHT) which is an important predictor of right ventricular failure and mortality following surgical intervention. Echocardiography and reversibility assessment of pulmonary vasculature resistance index (PVRI) may be useful in identifying high risk patients resulting in better procedural outcomes.

Trastuzumab induced cardiotoxicity in Auckland

Trastuzumab improves the prognosis of HER2 positive breast cancers but is associated with a decline in cardiac function. We looked at the incidence of Trastuzumab induced cardiotoxicity (TIC) in Auckland, defined as a reduction of LVEF of ≥5% to <55% with symptoms of heart failure or an asymptomatic reduction of the LVEF of ≥10% to <55%.

Effects of pre-hospital ECG transmission for ST-elevation myocardial infarction in Counties Manukau

In April 2013 the St John’s Ambulance Service began transmitting ECGs electronically to the Middlemore emergency department (MMH ED) to enable earlier catheter lab activation and out-of-hours bypass to Auckland City Hospital (ACH) for ST-elevation myocardial infarction (STEMI) patients. We assessed whether these changes further reduced time to primary PCI.

Variability and prognostic significance of antioxidant enzymes in acute coronary syndromes (ACS)

Glutathione peroxidase (GPx) and superoxide dismutase (SOD) are antioxidant enzymes which scavenge reactive oxygen species (ROS) and protect against oxidative stress. The variance and prognostic significance of these enzymes in ACS is unclear. This study examined the relationship between GPx and SOD activity and MACE following ACS.

Short to medium term outcome of Bioresorbable Scaffolds for treatment of coronary stenosis: The Christchurch experience

Bioresorbable Scaffolds (BRS) for the treatment of coronary stenosis involves the use of a temporary polymeric scaffold to maintain normal arterial curvature, allow return of vasomotion and enable positive remodelling without a longterm metallic cage. We aimed to determine short-medium term outcomes of patients undergoing percutaneous coronary intervention (PCI) with BRS.

Characteristics, outcomes, and complications during the first year of coronary rotational atherectomy at Middlemore Hospital

Coronary Rotational Atherectomy (CRA) is a complex intervention to treat heavily calcified coronary atherosclerosis. Calcified disease is common at Middlemore Hospital due to high prevalence of diabetes, chronic kidney disease (CKD) and elderly population. We review characteristics and outcomes of the first year of CRA at our hospital.
