RESUMO

OBJECTIVE: To determine the utility of exercise electrocardiography testing (EET) in evaluating suspected coronary artery disease in a remote Australian setting where a significant proportion of patients are Indigenous Australians. DESIGN: Retrospective cohort study with grouping based on EET results. PATIENTS AND SETTING: 268 patients with suspected coronary artery disease who underwent EET at Alice Springs Hospital--a specialist teaching hospital in Central Australia with no resident specialist cardiology service--in the period 1 June 2009 to 31 May 2010. MAIN OUTCOME MEASURES: Diagnosis of coronary artery disease, based on coronary angiography and/or admission with acute coronary syndrome, in the 24 months after EET. RESULTS: Indigenous patients were younger, more likely to be women and were twice as likely as non-Indigenous patients to have a chronic disease. Indigenous patients and those with a chronic disease had a higher proportion of inconclusive results. Completed EET had a positive predictive value of 48.1% (95% CI, 28.7%-68.1%) and a negative predictive value of 96.5% (95% CI, 93.2%-98.5%). Similar results were seen among Indigenous and non-Indigenous patients. CONCLUSIONS: In regional and remote Australian settings, EET remains an important tool for the diagnosis of coronary artery disease. It is useful, and is reassuring to patients and clinicians if the result is negative, particularly in a remote Indigenous Australian population with a significant burden of cardiovascular risk.

RESUMO

OBJECTIVE: To describe the case characteristics and outcomes of patients hospitalised with pandemic (H1N1) 2009 influenza infection during the first 2 months of the epidemic. DESIGN, PARTICIPANTS AND SETTING: Prospective case series of 112 patients admitted to seven hospitals in Melbourne with laboratory-confirmed pandemic (H1N1) 2009 influenza between 1 May and 17 July 2009. MAIN OUTCOME MEASURES: Details of case characteristics, risk factors for severe disease, treatment and clinical course. RESULTS: Of 112 hospitalised patients, most presented with cough (88%) and/or fever (82%), but several (4%) had neither symptom. A quarter of female patients (15) were pregnant or in the post-partum period. Patients presenting with multifocal changes on chest x-ray had significantly longer hospital lengths of stay, and were more likely to require intensive care unit admission. Thirty patients required admission to an intensive care unit, and three died during their acute illness. The median length of intensive care admission was 10.5 days (interquartile range, 5-16 days). CONCLUSIONS: This study highlights risk factors for severe disease, particularly pregnancy. Clinical and public health planning for upcoming influenza seasons should take into account the spectrum and severity of clinical infection demonstrated in this report, and the need to concentrate resources effectively in high-risk patient groups.
