Zusman O, et al. - Researchers compared temporal changes in European Society of Cardiology (ESC) acute myocardial infarction (AMI) quality indicator (QI) attainment in the United Kingdom and Israel via data cross-walking using information from the Myocardial Ischemia National Audit Project and the Acute Coronary Syndrome in Israel Survey for matching 2-month periods in 2006, 2010, and 2013. Compared with patients in Israel (n=5,647), the UK patients (n=17,068) were older, more likely to be women, and had less diabetes, dyslipidemia, and heart failure. Israeli patients had lower baseline ischemic risk than the UK patients. Among those in the Israeli cohort, they observed overall higher rates of coronary angiography (87.6% vs 64.8%) and percutaneous coronary intervention (70.3% vs 41.0%) vs those in the UK cohort. A higher increase in composite QI performance was noted in the UK group (1.0%–86.0%) vs those in the Israel group (70.2%–78.0%). Patients in both countries exhibited decline in mortality rates at 30 days, with lower rates in Israel in 2013 (4.2% vs 7.6%). Composite QI adherence-adjusted for GRACE risk score was noted to be inversely associated with 30-day mortality. These findings suggested that country-specific opportunities for improved healthcare delivery could be assessed via international implementation of the ESC AMI QIs.
