Type 2 myocardial infarction: the potential for early detection

Aim . To evaluate the potential of using factors associated with type 2 myocardial infarction (MI) for its early diagnosis. Material and methods . This prospective study included 204 patients diagnosed with acute coronary syndrome (ACS). At the time of admission, each patient underwent standard examinations for ACS patients. The 1-year stage consisted of telephone survey of patients on the course of long-term postinfarction period. There were following endpoints: death, recurrent coronary events and hospitalization. Result . Patients with type 2 MI accounted for 10,8% (n=22) of the entire analyzed sample. A model for prehospital diagnosis of probable type 2 MI has been developed. The model included clinical and history data that allow to suggest the type 2 MI course without invasive and laboratory studies. The model included signs (body mass index ≥35, kg/m 2 , atrial fibrillation+Killip I, hemoglobin <110 g/l within 1 year before MI, chronic obstructive pulmonary disease), the most common in type 2 MI patients according to own data and previous studies. Conclusion . A model of prehospital clinical assessment of MI risk has been developed for making a preliminary diagnosis and forming different patient streams at the admission stage for the final verification of the diagnosis.
