Value of normal or mild coronary artery disease on angiography during workup of suspected angina pectoris

Coronary angiography is the standard technique for assessment of coronary artery disease (CAD). In many patients investigated with angiography, no or minimal CAD (<50% stenosis) is detected. It is uncertain how this “negative” result influences subsequent management and outcomes. We reviewed characteristics and outcomes in a contemporary cohort of patients with suspected angina pectoris and subsequently “negative” coronary angiography. T. Wang, T. Oh, C. Samaranayake, T.

Utility of pre-catheterisation high-sensitivity troponin T in patients without obstructive coronary artery disease

Myocardial infarction (MI) in patients subsequently shown to have no obvious, or trivial coronary artery disease (<50% stenosis) at angirography is seldom studied, but may be attributable to either a primary coronary event or, less commonly, type 2 MI. Recently developed, high-sensitivity troponin T (hs-TnT) assays have increased sensitivity for detection of minor degrees of myocardial necrosis, improving MI detection rate. We assessed the prognostic utility of pre-catheterisation hs-TnT in patients without angiographically significant coronary narrowing.

Seven year study of surgery for infective endocarditis: The contemporary Auckland City Hospital experience

Infective endocarditis remains a heterogeneous disease with high mortality, and surgery is required in approximately half for resultant heart failure, uncontrolled infection or embolism prevention. Several recent studies advocate operating early to have superior outcomes. We reviewed the characteristics, timing and outcomes of cardiac operations performed for infective endocarditis at Auckland City Hospital.

Relationships between anticoagulation regimen, risk score and adverse outcomes in dialysis patients with atrial fibrillation

Atrial fibrillation (AF) is the commonest cardiac arrhythmia including in end-stage renal failure patients, and there is increasing evidence that anticoagulation leads to more harm than benefit in these patients on dialysis. We reviewed the characteristics, management and outcomes of end-stage renal failure patients in dialysis with AF with a focus on warfarin anticoagulation and risk scores.

Influence of cardioplegia techniques on outcomes after aortic valve replacement

Dual anterograde and retrograde cardioplegia delivery, warm induction and hotshot delivery had previously been shown to confer myocardial protection, but have not been studied for over a decade. High-sensitivity troponins (hs-Tn) are now the recommended biomarkers for assessing myocardial necrosis. We compared the degree of hs-TnT release and outcomes of aortic valve replacement (AVR) by these cardioplegia techniques.

Features and outcomes of eosinophilic myocarditis: A single-centre case series

Eosinophilic myocarditis (EM) is a rare and potentially fatal entity characterised by inflammation with infiltrating eosinophils. Limited published data are available documenting presentation, management and prognosis. We report these data in a series of patients with EM treated at Auckland City Hospital.

Elevation of aspartate aminotransferase predicts mortality after coronary artery bypass grafting

Cardiac troponins are the recommended biomarkers for diagnosing myocardial infarction (MI). Since troponins have become widely available, the roles of other less specific biomarkers have been seldom studied. Aspartate aminotransferase (AST) not only correlates with MI, but also with liver injury due to ischaemia or congestion. We assessed whether post-operative AST levels were associated with adverse outcomes after contemporary coronary artery bypass grafting (CABG).

Disparities of outcomes between Pacific Island and European patients undergoing coronary artery bypass grafting

Ischaemic heart disease remains the single most common cause of mortality in New Zealand. Significant disparities exist in terms of cardiovascular risk factors, events and access to interventions across various ethnic groups. We compared the characteristics and outcomes of coronary artery bypass grafting (CABG) between Pacific and European patients.
