BACKGROUND Amphetamine-associated cardiomyopathy (AAC) is becoming an increasingly recognised entity. The characteristics and outcomes of these patients are poorly understood. METHODS Thirty patients admitted with heart failure and echocardiographic evidence of cardiomyopathy between 2005 and 2014 and who had a documented history of amphetamine abuse that(More)
OBJECTIVE We aimed to describe the evolution of ECG changes in TC compared with MI, and evaluate ECG features which might help to distinguish between these conditions. BACKGROUND Takotsubo cardiomyopathy (TC) can mimic both ST-elevation (STEMI) and non-ST-elevation myocardial infarction (NSTEMI) but management is different. Several electrocardiographic(More)
Echocardiography is the principal non-invasive tool for initial evaluation and longitudinal monitoring of patients with significant valvular heart disease. However echocardiography can be limited by poor acoustic windows, and is dependent on the skill and experience of the sonographer. Cardiovascular magnetic resonance (CMR) can provide a comprehensive(More)
INTRODUCTION Dilated cardiomyopathy (DCM) is associated with significant morbidity and mortality. Contrast-enhanced cardiac MRI (CE-CMR) can detect potentially prognostic myocardial fibrosis in DCM. We investigated the role of CE-CMR in New Zealand patients with DCM, both Maori and non-Maori, including the characteristics and prognostic importance of(More)
Coronary artery septic embolisation resulting in cardioembolic myocardial infarction (MI) is a rare complication of bacterial infective endocarditis (IE), representing <1% of complications related to IE. Diagnosis requires a combination of high clinical suspicion, coronary angiography, echocardiography and cultures of peripheral blood and/or embolic(More)
AIMS The patho-physiology of apical ballooning syndrome (ABS) has not been clearly defined. The aim of this study was to determine whether patients with a history of ABS are more likely to develop left ventricular (LV) mid-cavity or outflow tract obstruction, or have a greater regional LV contractile response to an adrenergic stimulus compared with normal(More)
BACKGROUND Apical ballooning syndrome (ABS) mimics myocardial infarction but is characterised by transient left ventricular (LV) dysfunction without significant coronary artery obstruction. METHODS We prospectively identified 100 consecutive patients presenting in the Auckland region between March 2004 and July 2010 and obtained clinical, laboratory,(More)
