AIMS: It is still unknown whether impaired myocardial perfusion helps to explain the higher mortality observed with ageing in patients with ST-segment elevation myocardial infarction (STEMI) treated with primary angioplasty. METHODS AND RESULTS: In 1548 consecutive patients with STEMI treated with primary angioplasty, myocardial perfusion was evaluated by myocardial blush grade (MBG) and ST-segment resolution. All clinical and follow-up data were prospectively collected. Advanced age was associated with a significantly higher clinical and angiographic risk profile. We found a linear relationship between increasing age, decreased myocardial perfusion, and higher 1-year mortality. After adjustment for baseline potential confounding variables, increased age was still significantly associated with impaired myocardial blush (MBG 0-1) (P=0.028), and ST-segment resolution (<50%) (P=0.007). At multivariable analysis both age (P<0.0001) and poor myocardial perfusion (P<0.0001) were independent predictors of 1-year mortality. CONCLUSION: This study shows that impaired reperfusion is an additional determinant of the poor outcome observed with advanced age in patients with STEMI undergoing mechanical revascularization.
