Key result
Although reperfusion therapy is increasingly utilized in real-world clinical settings, elderly patients with acute myocardial infarction remain underrepresented in major trials and require careful management due to complex comorbidities.
Why the study?
Does reperfusion therapy improve outcomes in elderly patients with acute myocardial infarction?
Does reperfusion therapy improve outcomes in elderly patients with acute myocardial infarction?
Reperfusion therapy, particularly PCI, is increasingly utilized and improves mortality in real-world elderly patients with acute myocardial infarction, despite their historical underrepresentation in major clinical trials.

Supports cautious reperfusion decisions in comorbid elderly AMI patients; leaves open dedicated randomized trials in this underrepresented group.
Although there has been great progress in reperfusion therapy, the role of coronary reperfusion for elderly patients with acute myocardial infarction has not been fully investigated. In general, mean age of the subjects in major trials was about 60 years old and approximately only 10 to 15% of patients were over age 75. On the other hand, large-scale registries such as the US national registry of myocardial infarction (NRMI) showed a higher prevalence of elderly (especially women) in the clinical setting. This discrepancy may be due to the fact that elderly patients with myocardial infarction have some difficulties in the treatment such as severe multi-vessel coronary lesions, non-cardiac complications and relatively high prevalence of adverse reactions to reperfusion therapy. Here we focus on the situation of elderly patients (especially those 75 years or older) with myocardial infarction in the "real world" clinical setting, showing the clinical changes and outcome of our registry in rural Japan: the Kochi AMI (KAMI) registry.

Takata et al. (2006) conducted a review in Acute myocardial infarction. Reperfusion therapy (Thrombolysis, Percutaneous coronary intervention) was evaluated. Although reperfusion therapy is increasingly utilized in real-world clinical settings, elderly patients with acute myocardial infarction remain underrepresented in major trials and require careful management due to complex comorbidities.
