Abstract
Treatment strategies and outcome of ST-elevation myocardial infarction (STEMI) have been mainly studied in middle-aged patients. With increasing lifetime expectancy, the proportion of octogenarians will substantially increase. We aimed to evaluate whether the benefit of currently recommended reperfusion strategies is maintained in octogenarians. Reperfusion therapy and in-hospital mortality were evaluated in 1,092 octogenarians and compared with 7,984 STEMI patients < 80 years old based on data from the prospective Belgian STEMI registry. The octogenarian STEMI group had more cardiovascular comorbidities, contained more female patients and presented more frequently with cardiac failure (Killip class > 1, 40 vs. 20 %) compared with their younger counterparts (all p < 0.05). Although the rate of thrombolysis was similar (9.2 vs. 9.9 %) between both groups, a conservative approach was chosen more frequently (13.8 vs. 4.7 %), while PCI was performed less frequently (76.9 vs. 85.4 %) in octogenarians (p < 0.001). Moreover, ischemic time and door-to-needle/balloon time were longer for octogenarians. In-hospital mortality for octogenarians was 17.8 vs. 5.5 % in the younger group [adjusted OR 2.43(1.92-3.08)]. In haemodynamically stable octogenarians, PCI seemed to improve outcome compared with thrombolysis or conservative treatment (5.7 vs. 12.7 vs. 8.5 %, p = 0.09). In octogenarians with cardiac failure, in-hospital mortality was extremely high independent of the chosen reperfusion therapy (34.6 vs. 31.6 vs. 36.3 %, p = 0.88). In-hospital mortality in octogenarian STEMI patients was high and related to a high prevalence of cardiac failure. Less PCI was performed in the octogenarian group compared with the younger patients, although mortality benefit of PCI was maintained in haemodynamically stable octogenarians.
