Randomized studies may often be burdened by the selective nature of patient inclusion thus not reflecting real-world outcomes. This is evident from the discrepancy in the mortality rates reported in major randomized trials enrolling patients with acute myocardial infarction (AMI), as compared with registry data.

The primary objective of this observational study is to assess short- and long-term outcomes of unselected, real-world patients presenting with AMI and treated with contemporary percutaneous coronary intervention (PCI).

Inclusion Criteria:

• Patients with acute myocardial infarction referred to catheterization laboratory for percutaneous coronary intervention

Exclusion Criteria:

• Initial acute myocardial infarction diagnosis not confirmed
• Patients with acute myocardial infarction not undergoing invasive coronary angiography

This registry is based on consecutive patients with the initial diagnosis of acute myocardial infarction on admission to hospital, who are referred to invasive treatment, i.e. invasive coronary angiography with an intention to perform percutaneous coronary intervention. The study population will include both retrospective, multi-center registry data starting with the year 2009, and the prospectively enrolled patients according to the same pre-specified, broad inclusion/exclusion criteria. The underlying intention is to short- and long-term outcomes of a large population of unselected, real-world patients presenting with AMI and treated with PCI.
