RESUMO

BACKGROUND: Spontaneous coronary artery dissection (SCAD) is an important but under-recognised cause of acute coronary syndrome (ACS), particularly in younger women. We assessed trends in the detection, management and outcomes of all patients with SCAD over 6 consecutive years. METHODS: All patients with first diagnosis of SCAD at Christchurch Public Hospital, New Zealand, between January 2014 and January 2020 were included. Patient management and outcomes were determined by retrospective review of medical records. SCAD presentations were compared to total ACS presentations, obtained from a national ACS (ANZACS-QI) database. RESULTS: We identified 113 patients with angiographic diagnosis of SCAD. Median age was 54 years (88% female). The detection of SCAD increased over the period, both as a total number (Kendall's τ 0.87, p=0.015) and as a proportion of all ACS (p value for trend <0.0001). In 2019, SCAD represented 2.4% of all ACS and 18% of ACS in females aged less than 60 years. The most common presentation was non-ST elevation myocardial infarction (NSTEMI) in 72%; and, there was an increase in NSTEMI compared with STEMI over the period (p=0.023). Initial strategy of percutaneous coronary intervention (PCI) was undertaken in 12% of patients, with a significant trend towards a more conservative approach over the study period (p=0.019). The rate of 30-day major adverse cardiovascular events (MACE) was 8.8% overall, and significantly reduced over the study period to 3% in 2019 (p value for trend, 0.006). CONCLUSIONS: The detection of SCAD has increased and is a particularly important cause of ACS in younger women. This increase has been largely driven by an increasing number of NSTEMI patients diagnosed with SCAD, associated with a significant improvement in 30-day MACE.

RESUMO

BACKGROUND: Countries with a high incidence of coronavirus 2019 (COVID-19) reported reduced hospitalisations for acute coronary syndromes (ACS) during the pandemic. This study describes the impact of a nationwide lockdown on ACS hospitalisations in New Zealand (NZ), a country with a low incidence of COVID-19. METHODS: All patients admitted to a NZ Hospital with ACS who underwent coronary angiography in the All NZ ACS Quality Improvement registry during the lockdown (23 March - 26 April 2020) were compared with equivalent weeks in 2015-2019. Ambulance attendances and regional community troponin-I testing were compared for lockdown and non-lockdown (1 July 2019 to 16 February 2020) periods. FINDINGS: Hospitalisation for ACS was lower during the 5-week lockdown (105 vs. 146 per-week, rate ratio 0•72 [95% CI 0•61-0•83], p = 0.003). This was explained by fewer admissions for non-ST-segment elevation ACS (NSTE-ACS; p = 0•002) but not ST-segment elevation myocardial infarction (STEMI; p = 0•31). Patient characteristics and in-hospital mortality were similar. For STEMI, door-to-balloon times were similar (70 vs. 72 min, p = 0•52). For NSTE-ACS, there was an increase in percutaneous revascularisation (59% vs. 49%, p<0•001) and reduction in surgical revascularisation (9% vs. 15%, p = 0•005). There were fewer ambulance attendances for cardiac arrests (98 vs. 110 per-week, p = 0•04) but no difference for suspected ACS (408 vs. 420 per-week, p = 0•44). Community troponin testing was lower throughout the lockdown (182 vs. 394 per-week, p<0•001). INTERPRETATION: Despite the low incidence of COVID-19, there was a nationwide decrease in ACS hospitalisations during the lockdown. These findings have important implications for future pandemic planning. FUNDING: The ANZACS-QI registry receives funding from the New Zealand Ministry of Health.

RESUMO

The All New Zealand Acute Coronary Syndrome Quality Improvement programme (ANZACS-QI) uses a web-based system to create a clinical registry of patients with acute coronary syndrome (ACS) and other cardiac problems admitted to hospitals across New Zealand. This detailed clinical registry is complemented by parallel analyses of, and individual linkage to, New Zealand's multiple routine health information datasets. The programme is primarily designed to support secondary care clinicians to implement evidence based guidelines and to meet national performance targets for New Zealand cardiac patients. ANZACS-QI simultaneously generates a large-scale research database and provides an electronic data infrastructure for clinical registry studies. ANZACS-QI has been successfully implemented in all the 41 public hospitals across New Zealand where acute cardiac patients are admitted. By June 2015 25,273 patients with suspected ACS and 30,696 referred for coronary angiography were registered in ANZACS-QI. In this report we describe the development and national implementation of ANZACS-QI, its governance, the data collection processes and the current ANZACS-QI cohorts and available outputs.
