Reperfusion strategy for acute myocardial infarction in elderly patients aged 75 to 80 years

The increasing elderly population will influence the treatment policies adopted in cases of acute myocardial infarction. Considering reperfusion therapy in elderly patients with acute myocardial infarction, we compared three strategies, as follows: primary percutaneous coronary intervention (primary PCI: n = 26), facilitated PCI with half the standard dose of mutant tissue-type plasminogen activator (t-PA) (half + PCI: n = 24), and facilitated PCI with a standard dose of mutant t-PA (standard + PCI: n = 15) between patients 75 and 80 years of age. The rate of acquisition of thrombolysis in myocardial infarction (TIMI-3) flow on initial coronary arteriography was significantly lower in the primary PCI group than in the other two groups (7.7% in the primary PCI group vs 60% in the half + PCI and 66.7% in the standard + PCI group). The incidence of hemorrhagic complications including blood transfusion was not significantly different between primary PCI and facilitated PCI. Considering reperfusion therapy in elderly patients with acute myocardial infarction, we concluded that facilitated PCI may be effective in elderly patients aged 75–80 years.
