A tale of two registries: Trends and outcomes of percutaneous coronary intervention in two transatlantic populations

Key Points Patients undergoing percutaneous coronary intervention (PCI) in the state of Michigan have more comorbidities compared to patients undergoing PCI in the United Kingdom. While the adoption of radial artery access for PCI has increased steadily over time in both Michigan and the United Kingdom, the use of radial access was significantly greater in the UK at all time points compared to Michigan for all PCI indications. The use of mechanical support during PCI has increased over time in Michigan but decreased over time in the United Kingdom.
