Baseline characteristics and practice patterns were assessed using all patients (275 021 Swedish cohort, 9883 US cohort). Mortality was analysed using a random-effects Cox model, restricted to patients treated at university hospitals and excluding those with cardiac arrest or cardiogenic shock (108 136 Swedish cohort, 9592 US cohort). The Swedish cohort was older, had a greater proportion of men, and was more likely to smoke (all P &amp;lt; 0.001). The US cohort had a higher body mass index and was more likely to have diabetes, hyperlipidaemia, prior PCI, congestive heart failure, and peripheral arterial disease (all P &amp;lt; 0.001). Sweden had lower rates of PCI for stable angina and lower use of mechanical circulatory support (all P &amp;lt; 0.001). More STEMI patients were treated with only heparin as anticoagulation in Sweden, even in the contemporary era. There was earlier adoption and increased utilization of ticagrelor and radial access in Sweden, while there was earlier use of drug-eluting stents in the US. Fractional flow reserve was used more frequently in Sweden. There was no difference in adjusted all-cause mortality 1 year post-PCI for any indication between university hospitals in Sweden and the US (hazard ratio [HR] 1.09; 95% CI 0.86\u20131.37; P = 0.48),
