Abstract

Presentation and outcomes of patients with ST-elevation myocardial infarction (STEMI) may change during viral pandemics. We compared symptom-tocall (STC), call-to-balloon (CTB), doorto-balloon (DTB) times; high-sensitivity troponin (hs-cTnI) levels; and survival of patients (n=39) during the first wave of the COVID-19 pandemic (defined as a 'COVID period' starting four weeks before lockdown) to historical controls from a 'pre-COVID period' (n=45). STEMI admissions fell one week before lockdown by 29%. Median STC times began to rise one month before lockdown (54 vs . 25 min, p=0.06), with peak increases between 9 March and 5 April (166 vs . 59 min, p=0.04). Median CTB and DTB times were unchanged. Mean peak hs-cTnI increased during COVID-19 (15,225 vs . 8,852 ng/ml, p=0.004). Six-month survival following all STEMI reduced (82.1% vs . 95.6%, p<0.05). STC times are the earliest indicator that STEMI-patient behaviour changed four weeks before lockdown, correlating with higher troponin levels and reduced survival. These early signals could guide public health interventions during future pandemics.<br />Competing Interests: Conflicts of interest None declared.<br /> (Copyright © 2022 Medinews (Cardiology) Limited.)
