RESUMO
INTRODUCTION: There is conflicting information regarding the contemporary incidence of first acute myocardial infarction (AMI) in Australia. We sought to document the regional variations in first AMI incidence in a large health district. METHODS: We identified all patients presenting with first AMI in the Hunter region of New South Wales from 2004 to 2013. We calculated age and gender adjusted incidence of AMI and evaluated differences between patients from regional and metropolitan areas. We assessed 30-day and 12-month outcomes, including mortality, through linkage with the NSW Registry of Births Deaths and Marriages. RESULTS: The incidence of first AMI in regional areas was persistently higher throughout the study compared to metropolitan areas (IRR 1.244; 95% CI 1.14-1.35; p≤0.001). There were no significant differences between regional and metropolitan areas in 30-day and 12-month outcomes following presentation with first AMI. CONCLUSIONS: The study demonstrates persistently higher rates in regional compared to metropolitan areas, supporting the need for implementation of targeted intervention and prevention strategies.

Cardiovascular disease and cancer are 2 of the leading causes of death worldwide. Although improvements in outcomes have been noted for both disease entities, the success of cancer therapies has come at the cost of at times very impactful adverse events such as cardiovascular events. Hypertension has been noted as both, a side effect as well as a risk factor for the cardiotoxicity of cancer therapies. Some of these dynamics are in keeping with the role of hypertension as a cardiovascular risk factor not only for heart failure, but also for the development of coronary and cerebrovascular disease, and kidney disease and its association with a higher morbidity and mortality overall. Other aspects such as the molecular mechanisms underlying the amplification of acute and long-term cardiotoxicity risk of anthracyclines and increase in blood pressure with various cancer therapeutics remain to be elucidated. In this review, we cover the latest clinical data regarding the risk of hypertension across a spectrum of novel anticancer therapies as well as the underlying known or postulated pathophysiological mechanisms. Furthermore, we review the acute and long-term implications for the amplification of the development of cardiotoxicity with drugs not commonly associated with hypertension such as anthracyclines. An outline of management strategies, including pharmacological and lifestyle interventions as well as models of care aimed to facilitate early detection and more timely management of hypertension in patients with cancer and survivors concludes this review, which overall aims to improve both cardiovascular and cancer-specific outcomes.

Aims: Cardiac catheterization procedures are typically performed with local anaesthetic and proceduralist guided sedation. Various fasting regimens are routinely implemented prior to these procedures, noting the absence of prospective evidence, aiming to reduce aspiration risk. However, there are additional risks from fasting including patient discomfort, intravascular volume depletion, stimulus for neuro-cardiogenic syncope, glycaemic outcomes, and unnecessary fasting for delayed/cancelled procedures. Methods and results: This is an investigator-initiated, multicentre, randomized trial with a prospective, open-label, blinded endpoint (PROBE) assessment based in New South Wales, Australia. Patients will be randomized 1:1 to fasting (6â h solid food and 2â h clear liquids) or to no fasting requirements. The primary outcome will be a composite of hypotension, hyperglycaemia, hypoglycaemia, and aspiration pneumonia. Secondary outcomes will include patient satisfaction, contrast-induced nephropathy, new intensive care admission, new non-invasive or invasive ventilation requirement post procedure, and 30-day mortality and readmission. Conclusions: This is a pragmatic and clinically relevant randomised trial designed to compare fasting verse no fasting prior to cardiac catheterisation procedures. Routine fasting may not reduce peri-procedural adverse events in this setting.
