Key result
Modern AMI presentation linked to ~3-fold higher rate of atypical onset versus 1984.
Why the study?
Changes in the incidence, onset, and course of acute myocardial infarction among the urban population over time were not well characterized.
Population
739 AMI cases in 1984 and 983 AMI cases in 2013 among urban population aged 20 years and older in Tomsk
Comparison
AMI cases in 1984 vs AMI cases in 2013
Design
Observational analytic database study from WHO AMI Registry (RAMI)

Alerts clinicians to rising atypical AMI in older adults; extends understanding of temporal shifts in MI epidemiology.

The demographic shift towards an older population with acute myocardial infarction over three decades has led to more atypical presentations and higher complication rates, necessitating optimized care for elderly patients.
Garganeeva et al. (2016) conducted an observational in Acute myocardial infarction (n=1,722). Time period (2013) vs. Time period (1984) was evaluated on Incidence, onset, and course of acute myocardial infarction. The year 2013, compared to 1984, was associated with an older age of AMI patients, a three-fold increase in atypical clinical onset, and a higher frequency of Q-wave MI and complications.
