The optimal reperfusion strategy in very elderly patients with ST-segment elevation myocardial infarction is still a subject of debate. The aim of this multicenter study was to determine the medium-term outcomes of nonagenarians after primary percutaneous intervention for ST-segment elevation myocardial infarction. A systematic review of the databases of 7 Italian centers showed that these had performed 5,023 primary angioplasties over the previous 5 years, 100 of which (2%) involved patients >/=90 years old. Thirty-five subjects were in Killip class III or IV at time of presentation, 78 had multivessel coronary artery disease, and mean ejection fraction was 0.40 +/- 0.12%. In-hospital mortality was 19% and was significantly higher in patients with shock (58% vs 10%, p <0.001). Survival rate after 6 months was 68%: 16% in those with Killip class IV at admission and 81% in the remaining patients (p <0.001). Cox regression analysis identified 3 independent predictors of 6-month mortality: cardiogenic shock at presentation (hazard ratio [HR] 10.82, 95% confidence interval [CI] 4.51 to 25.93, p <0.001), Thrombolysis In Myocardial Infarction myocardial flow after percutaneous coronary intervention (HR 0.19, 95% CI 0.07 to 0.50, p = 0.001), and abciximab administration (HR 0.32, 95% CI 0.13 to 0.78, p = 0.01). In conclusion, the results of this multicenter study suggest that selected nonagenarians with acute myocardial infarction benefit from successful primary angioplasty. The treatment does not affect the poor prognosis of patients presenting with cardiogenic shock, but the administration of abciximab seems to have a positive effect on 6-month mortality.
