BACKGROUND: Although smoking is known to be associated with cardiovascular diseases, the number of large-scale cohort studies on the association between smoking and atrial fibrillation (AF) is limited and the results obtained are also inconsistent, and even fewer studies have addressed the difference between the male and female genders. The present study was intended to clarify and quantify the association between smoking and the risk of AF in men versus women. METHODS: Using AF- and smoking-related keywords, a comprehensive literature search on PubMed, EMbase and Web of Science was conducted with a time limit until December 2016, which was followed by manual screening, quality assessment and data extraction...

A 28-year-old male was admitted to hospital with an acute ST-elevation myocardial infarction. This was in the context of recreational abuse of nitrous oxide. The prevalence of nitrous oxide use in Australia has not been formally quantified, however it is the second most commonly used recreational drug in the United Kingdom. Nitrous oxide has previously been shown to increase serum homocysteine levels. This patient was discovered to have an elevated homocysteine level at baseline, which was further increased after nitrous oxide consumption...

BACKGROUND: Limited information exists on whether changes in medical practices over the study decades have affected the outcomes of acute coronary syndrome (ACS) patients who undergo early coronary artery bypass surgery (CABG) during index hospitalisation. METHODS: Data on trends for early CABG referral and associated outcomes were obtained among 11,485 ACS patients enrolled in the biennial Acute Coronary Syndrome Israeli Surveys (ACSIS) 2000-2010. RESULTS: Among 11,485 patients, 566 (5%) were referred to early CABG...

BACKGROUND: Exercise treadmill test (ETT) is commonly the first-line investigation in troponin-negative chest pain patients. Inconclusive results are common and often lead to repeated functional testings. Coronary computed tomographic angiography (CCTA) has excellent negative predictive value for coronary artery disease detection and may play an important role in their diagnostic workup. We aim to analyse ETT and CCTA findings to understand their modern roles in intermediate risk chest pain population with inconclusive ETT...

BACKGROUND: A significant number of chronic thromboembolic pulmonary hypertension (CTEPH) patients will have an inoperable disease. Medical therapy and balloon pulmonary angioplasty (BPA) have provided alternate therapeutic options for patients with inoperable CTEPH, although there are a limited number of published studies examining the outcomes. Thus, our study aims to evaluate and compare the efficacy of medical therapy and BPA in patients with inoperable CTEPH. METHODS: An electronic search of six databases was performed and the search results were screened against established criteria for inclusion into this study...

BACKGROUND: Anticoagulation is the primary treatment for pulmonary embolism (PE). Inferior vena cava (IVC) filters are an adjunctive intervention to prevent recurrent pulmonary embolism. Long-term outcomes in elderly patients with contraindications to anticoagulation after IVC filter placement for prevention of recurrent pulmonary embolism have yet to be assessed. MATERIALS AND METHODS: Patients ≥60years of age, that had an IVC filter placed between January 1st, 2008 and February 2nd, 2013, with a primary diagnosis of pulmonary embolism, were included...

Martin Burtscher
INTRODUCTION: Annually, more than 100 million tourists with widely varying health and fitness status are attracted by the mountainous areas around the world. Whereas mountaineering activities may contribute to the well established beneficial effects of regular exercise, for certain individuals these activities are also associated with a relatively high risk of death. METHODS: This manuscript presents an updated overview of risk and protective factors for sudden cardiac death during leisure activities in the mountains...

Cardiogenic shock in the context of acute ST-elevation myocardial infarction (STEMI) remains a challenge to manage and results in significant mortality and morbidity, cardiac arrest in this setting even more so. The increase in myocardial oxygen demand and consumption with the use of inotropes is recognised as increasing mortality. Alternatives include the intra-aortic balloon pump (IABP), which has yet to be shown to improve outcomes, and extracorporeal membrane oxygenation (ECMO), which requires super-specialised techniques not widely available...

BACKGROUND: Surgical revascularisation in patients with acute myocardial infarction with ST-Segment Elevation (STEMI) is usually considered as a second choice when direct angioplasty/stent fails. However, improvements in surgical technique and postoperative care may justify coronary artery bypass grafting (CABG) in STEMI. METHODS: This was a retrospective analysis of prospectively gathered data of 135 patients with acute STEMI, treated with CABG in our department from February 2008 to December 2012...

BACKGROUND: Pulmonary hypertension (PH) can be caused by a fistula between the systemic and pulmonary arteries. Here, we report a case of PH due to multiple fistulas between systemic arteries and the right pulmonary artery where the ventilation/perfusion scan showed no perfusion in the right lung. METHODS: A 32-year-old male patient was hospitalised for community-acquired pneumonia. After treatment with antibiotics, the pneumonia was alleviated but dyspnoea persisted...

BACKGROUND: The Magnetic Navigation System (MNS) catheter was shown to be stable in the presence of significant cardiac wall motion and delivered more effective lesions compared to manual control. This stability could potentially make AV junctional reentrant tachycardia (AVNRT) ablation safer. The aim of this study is to describe the method of mapping and ablation of AVNRT with MNS and 3-D electro-anatomical mapping system (CARTO, Biosense Webster, Diamond bar, CA, USA) anatomical mapping, with a view to improve the safety of ablation...

BACKGROUND: Chronic kidney disease (CKD) is a known predictor for adverse outcomes in patients with advanced heart failure requiring left ventricular assist devices (LVADs). The effect of pre-LVAD glomerular filtration rate (GFR) on post-LVAD outcomes in CKD patients is not completely understood. Additionally, a subset of patients improve their GFR after LVAD placement. In this study we sought to determine the effects of pre-LVAD GFR on post-LVAD outcomes. METHODS: Two hundred and seventy consecutive patients with LVADs were enrolled...

BACKGROUND: Surgical mitral valve repair is the gold standard for treatment of mitral regurgitation. Recently, the transcatheter treatment of mitral regurgitation with the MitraClip(®) device (Abbot Vascular Structural Heart, Menlo Park, CA) has demonstrated promising results in treating patients not amenable for surgical correction of mitral valve regurgitation. Most patients reported in the literature requiring surgical bailout after MitraClip treatment presented with residual or recurrent mitral valve regurgitation...

BACKGROUND: Warfarin remains a widely used anticoagulant but application in the remote context is not well documented. This study aimed to assess in more detail whether warfarin is being utilised effectively in Australia's most isolated and remote areas. METHODS: Retrospective cohort analysis of 2013 captured international normalised ration (INR) results from people engaged in long term warfarin usage within a number of remote Northern Australian communities. Assessment of monitoring, effectiveness of dosing and complication rates was undertaken...

BACKGROUND: Research suggests that female patients with acute coronary syndrome (ACS) experience delays in emergency department (ED) management and are less likely to receive guideline-based treatments and referrals for follow-up testing. Women are often found to have poorer clinical outcomes in comparison to men. This study aimed to assess current sex differences in the presentation, management and outcomes of patients with undifferentiated chest pain presenting to a tertiary ED. METHODS: Data were analysed from two prospective studies conducted at a single Australian site between 2007 and 2014...

BACKGROUND: Assessment of physical activity (PA) for cardiac rehabilitation (CR) participants is critical to monitor changes. However, the validity and reliability of PA measures to assess PA throughout the day, not only during exercise training, is poorly investigated. AIM: To establish a reliable and valid measure to assess overall PA in CR participants. METHODS: A narrative literature review was performed based on a systematic search of EMBASE, CINAHL, MEDLINE and PubMed databases...

BACKGROUND: Patients with panic disorder experience symptoms such as palpitations, chest pain, dizziness, and breathlessness. Consequently, they may attend the Emergency Department (ED) to be assessed for possible emergency medical conditions. Recognition of panic disorder within the ED is low. We sought to establish the prevalence of panic disorder in patients presenting to the for ED investigation of potential acute coronary syndrome. We also sought to characterise the cohort of patients with panic disorder in terms of presenting symptoms, risk factors, medical history and major adverse cardiac events (MACE)...

BACKGROUND: The uptake of bone-seeking radiotracers in the amyloid heart is well recognised. 99(m)Tc-DPD has been shown to be highly sensitive for cardiac transthyretin (ATTR) amyloid in an overseas population, but is not registered for use in Australia. We explored its utility as a diagnostic tool within our population. METHODS: Patients diagnosed with AL and ATTR (wild-type and inherited) cardiac amyloidosis were prospectively recruited from the Princess Alexandra Hospital Amyloidosis Centre...
