- Abstract
This study used data from the ANZACS-QI registry to evaluate the impact of a nationwide lockdown on ACS hospitalisations in NZ. All patients admitted to hospital with ACS who underwent coronary angiography during the lockdown (23 March - 26 April 2020) were compared with those admitted during equivalent weeks in 2015-2019. Ambulance attendances and regional community troponin-I testing during lockdown were also assessed. Hospitalisations for ACS were lower during the 5-week lockdown (rate ratio 0.72, 95% CI 0.61-0.83; p=0.003), due mainly to fewer admissions for non-ST-segment elevation ACS (NSTE-ACS; p=0.002). Door-toballoon times for ST-segment elevation myocardial infarction (STEMI) were comparable in lockdown and non-lockdown periods. For NSTE-ACS, there was an increase in percutaneous revascularisation (59% vs 49%; p<0.001) and a decrease in surgical revascularisation (9% vs 15%; p=0.005). There were fewer ambulance attendances for cardiac arrests during lockdown, but attendances for suspected ACS were comparable.
