Cardiovascular disease and COVID-19: Australian and New Zealand consensus statement.

INTRODUCTION: The coronavirus 2019 disease (COVID-19) pandemic is caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Pre-existing cardiovascular disease (CVD) increases the morbidity and mortality of COVID-19, and COVID-19 itself causes serious cardiac sequelae. Strategies to minimise the risk of viral transmission to health care workers and uninfected cardiac patients while prioritising high quality cardiac care are urgently needed. We conducted a rapid literature appraisal and review of key documents identified by the Cardiac Society of Australia and New Zealand Board and Council members, the Australian and New Zealand Society of Cardiac and Thoracic Surgeons, and key cardiology, surgical and public health opinion leaders. MAIN RECOMMENDATIONS: Common acute cardiac manifestations of COVID-19 include left ventricular dysfunction, heart failure, arrhythmias and acute coronary syndromes. The presence of underlying CVD confers a five- to tenfold higher case fatality rate with COVID-19 disease. Special precautions are needed to avoid viral transmission to this population at risk. Adaptive health care delivery models and resource allocation are required throughout the health care system to address this need. CHANGES IN MANAGEMENT AS A RESULT OF THIS STATEMENT: Cardiovascular health services and cardiovascular health care providers need to recognise the increased risk of COVID-19 among CVD patients, upskill in the management of COVID-19 cardiac manifestations, and reorganise and innovate in service delivery models to meet demands. This consensus statement, endorsed by the Cardiac Society of Australia and New Zealand, the Australian and New Zealand Society of Cardiac and Thoracic Surgeons, the National Heart Foundation of Australia and the High Blood Pressure Research Council of Australia summarises important issues and proposes practical approaches to cardiovascular health care delivery to patients with and without SARS-CoV-2 infection.

Timely treatment for acute myocardial infarction and health outcomes: an integrative review of the literature.

BACKGROUND: Coronary heart disease is the most common condition affecting Australians. The time sensitive nature of treating ST-segment elevation myocardial infarction (STEMI) has been the subject of extensive research for several years. Despite important advances in strategies to reduce time to treatment, time continues to represent a major determinant of mortality and morbidity. Door to balloon time (DTBT) is a key indicator of quality of care for STEMI. Nurses play a pivotal role in streamlining the care processes to influence timely management of STEMI. PURPOSE: The aim of this paper is to review the evidence on the time to treat STEMI, the associated factors impacting upon health outcomes and explore systems of care that reduce time to treatment, using an integrative review approach. METHOD: Established databases were searched from 2000 to 2012. The search terms 'myocardial infarction', 'emergency medicine', 'angioplasty balloon', 'time factors', 'treatment outcome', 'mortality', 'prognosis', 'female', 'age factors', and 'readmission', were used in various combinations. Research studies that addressed the aims of this paper were examined. FINDINGS: Twenty-nine papers were included in this integrative review. The literature demonstrates a strong relationship between shorter DTBT and reduced in-hospital mortality. Factors such as age, gender, time of presentation and co-morbid condition were associated with increased in-hospital mortality. There is sparse literature examining the effect timely reperfusion has on longer-term mortality and other longer-term outcomes such as readmission rates and occurrence of heart failure. Additionally, strategies that effectively reduced DTBT were identified, yet little has been reported on the impact reduced DTBT has had upon health outcomes and whether these improvements were sustained. CONCLUSION: Whilst the importance of timely reperfusion is now well recognised, additional efforts to streamline the process of care and demonstrate sustained improvement for STEMI patients is required. Nurses in the areas of emergency medicine and cardiac care, play an essential role in facilitating this.

Introducing the Cardibra: a randomised pilot study of a purpose designed support bra for women having cardiac surgery.

BACKGROUND: Cardiac nurses instruct women to wear a brassiere (bra) after a sternotomy for cardiac surgery to reduce lateral tension on the wound. However this practice is rarely implemented because regular bras impede nursing care in the immediate postoperative period. The Cardibra was developed to address the inadequacies of the regular bra and provide an alternate method of breast support. AIM: To develop a purpose designed support bra (the Cardibra) and evaluate its effectiveness on sternal wound healing and the reduction of pain for women who had a sternotomy for cardiac surgery. METHODS: The study consisted of two stages. Stage 1 described the development of the Cardibra. Stage 2 was a pilot study of a clinical trial, prospective, randomised two-group design. The treatment group consisted of 10 women using the Cardibra immediately following surgery and the control group of 10 who wore a regular bra 3 days post surgery. Repeated measures at six time points assessed pain levels and wound healing. RESULTS: This study indicated that the Cardibra might have beneficial therapeutic effects on pain levels and wound healing up to day 14 after cardiac surgery. CONCLUSION: This innovative device may offer therapeutic benefits to women following cardiac surgery.
