Incidence, timing and variation in unplanned readmissions within 30-days following isolated coronary artery bypass grafting.

Background: Coronary Artery Bypass Grafting (CABG) is the most common cardiac surgery, yet little is known about unplanned readmissions after CABG despite increasing clinical and policy focus on reducing readmissions. We assessed the incidence, timing, and reasons for unplanned readmission within 30 days of CABG and evaluated for variation in readmission rates across hospitals in Australia and New Zealand (ANZ).

Method: We identified isolated CABG procedures from 2013 to 2017 across all public and most private hospitals in ANZ.

Differences between sexes in STEMI treatment and outcomes with contemporary primary PCI.

Background: Historically, differences in timely reperfusion and outcomes have been described in females who suffer ST-segment elevation myocardial infarction (STEMI). However, there have been improvements in the treatment of STEMI patients with contemporary Percutaneous Coronary Intervention (PCI) strategies.

Methods: Comparisons between sexes were performed on STEMI patients treated with primary PCI over a 4-year period (January 1, 2017-December 31, 2020) from the Queensland Cardiac Outcomes Registry.

Hospital costs for unplanned re-admissions within 30 days of hospitalisations with heart failure, Australia, 2013-2017: a retrospective cohort study.

Objectives: To assess the direct hospital costs for unplanned re-admissions within 30 days of hospitalisations with heart failure in Australia; to estimate the proportion of these costs attributable to potentially preventable re-admissions.

Study Design: Retrospective cohort study; analysis of linked admitted patient data collections data.

Setting, Participants: People admitted to hospital (all public and most private hospitals in Australia) with primary diagnoses of heart failure, 1 January 2013 - 31 December 2017, who were discharged alive and re-admitted to hospital at least once (any cause) within 30 days of discharge.

Clinical characteristics and outcomes of Australian and Indian ST-segment elevation myocardial infarction (STEMI) patients treated with primary percutaneous coronary intervention (PCI).

Introduction: The incidence of STEMI and subsequent mortality has been reported to be higher in Indian populations compared to developed countries. However, there is limited data directly comparing contemporary primary percutaneous coronary intervention (pPCI) treatment strategies and clinical outcomes for STEMI patients between developed and developing countries.

Materials And Methods: We compared population demographics, procedural characteristics, times to reperfusion and mortality in STEMI patients treated with pPCI between two tertiary referral centers in India and Australia respectively over a 3-year period (1st Jan 2017-31st Dec 2019).

Point-of-care high-sensitivity cardiac troponin in suspected acute myocardial infarction assessed at baseline and 2 h.

Background And Aims: Strategies to assess patients with suspected acute myocardial infarction (AMI) using a point-of-care (POC) high-sensitivity cardiac troponin I (hs-cTnI) assay may expedite emergency care. A 2-h POC hs-cTnI strategy for emergency patients with suspected AMI was derived and validated.

Methods: In two international, multi-centre, prospective, observational studies of adult emergency patients (1486 derivation cohort and 1796 validation cohort) with suspected AMI, hs-cTnI (Siemens Atellica® VTLi) was measured at admission and 2 h later.
