Study Summary

The Registry of Acute Myocardial Infarction (RAMI) aims at regular and centralized acquiring and processing standard information about verified and suspected cases of acute myocardial infarction (AMI), monitoring of AMI cases, and establishing AMI diagnosis based on standard diagnostic criteria by doctors involved in the registry. The RAMI obtains data from all medical institutions, which could potentially document any cases of suspected AMI.

Eligibility Criteria

Inclusion

Inclusion Criteria:

  • age of at least 20 years;

  • being a resident or visitor of the city of Tomsk at a time of AMI onset;

  • the presence of definite AMI or possible AMI. Definite AMI is diagnosed in thepresence of characteristic ECG changes, regardless of clinical course and changes inserum enzymes; or the presence of typical pain syndrome, "ambiguous" ECG changes,and definite increase in the activity of serum enzymes i.e. exceeding the upperlimit of normal by 25% or more; or macroscopically detected focus of myocardialnecrosis and (or) fresh thrombotic occlusion of the coronary artery. Possible AMI isregistered in the presence of typical pain syndrome with ambiguous ECG changes andan ambiguous (up to 25%) increase in the levels of serum enzymes; or the presence ofobstruction in the lumen of at least one coronary artery by at least 50% and (or)the presence of a post-infarction scar in the myocardium with a diameter of 0.5 cmor more, while simultaneously excluding a non-coronary cause of death. In case ofatypical clinical picture, ambiguous or absent ECG changes, when the enzyme levelsare not determined or their activity does not reach a pathological level, AMI caseis considered unconfirmed. In the absence of data that could confirm or not confirmAMI, the case is interpreted as "insufficient data"

Exclusion

Exclusion Criteria:

  • none.

Study Description

The study implements the methodology recommended by the World Health Organization (WHO) using unified diagnostic criteria (clinical, biochemical, electrocardiographic, and autopsy) for acute myocardial infarction (AMI). All primary information is recorded in a special primary registration card, which has been subject to updates in accordance with the requirements. All accumulated data is stored in RAMI analytic database. The database is designed and developed specifically for recording, accumulating, archiving, and statistical processing of collected data. It is equipped with a web user interface, a universal environment for generating consolidated distribution reporting, and the ability to import analytical data into expert analytical systems produced by other manufacturers. Data storage is implemented using the Oracle database management system. The information and analytical system of RAMI has passed the procedure of state registration of the database. Each reported case after the first 28 days from disease onset is assigned a specific diagnostic category (definite myocardial infarction, possible myocardial infarction, unconfirmed myocardial infarction, and insufficient data). At the end of each year of study, RAMI team calculates and analyzes the main epidemiological parameters, characterizing the disease distribution in the studied population (the city of Tomsk, Russian Federation) including morbidity, mortality, and lethality (general, in-hospital, and pre-hospital).
