Percutaneous coronary interventions in octogenarians: Acute and 12 month results in a large single‐centre experience

OBJECTIVES: To review the results of PCI in patients aged >or=80 years. BACKGROUND: Octogenarians represent a growing proportion of patients treated with PCI; in this subset of high-risk patients, the role of complete revascularization is still controversial. METHODS: We examined in-hospital, 30 days, and 12-month events in 356 patients aged >or=80 years submitted to PCI from 2004 to 2006 and 754 patients aged <80 years treated in 2006. RESULTS: Octogenarians had a higher risk profile. A complete revascularization was obtained in 48% of them and in 65% of younger patients (P < 0.001); glycoprotein IIb/IIIa inhibitors (GPI) use was common in both groups (43 vs. 46.5%). In-hospital mortality was higher in octogenarians (3.9 vs. 1.3%, P = 0.01) as well as vascular complications (2.8 vs. 1%, P = 0.058). Mortality resulted 5.9 vs. 1.2% at 30 days (P < 0.001), and 16.3 vs. 3.9% at 12 months (P <0.001) in the two groups whereas repeat revascularization procedures did not differ (9.3 vs. 8.4%, respectively). In patients aged >or=80, there was no difference in 12 months total events (20 vs. 28%, P = 0.07) and repeat revascularizations (8 vs. 10%, P = 0.498) in completely or uncompletely revascularized subjects. At multivariate analysis age (P = 0.002), diabetes (P = 0.002), three vessel disease (P = 0.020) and procedural success (P = 0.002) were independent predictors of total events at 12 months. CONCLUSIONS: In our experience, frequent GPI use and multivessel PCI in 41% of >or=80 years-old patients resulted in good immediate and mid-term clinical outcomes, irrespective of the completeness of revascularization achieved.
