Age is not a bar to PCI: Insights from the long-term outcomes from off-site PCI in a real-world setting

We sought to analyze the percutaneous coronary intervention (PCI) outcomes of very elderly patients (V. Eld. group, age >80 years) and compare their outcomes to a less elderly cohort (Eld. group, age 75-80 years) traditionally reported in the literature.

Limited data exist on peri-procedural and long-term outcomes following PCI in the V. Eld. (age >80 years), with under-representation of this cohort in randomized controlled trials. These patients present with advanced complex coronary disease and multiple comorbidities.

All 580 consecutive patients aged ≥75 years (age 80 ± 4.9 years, 57.4% males) undergoing PCI between April 2006 and November 2011 were included. A total of 624 consecutive lesions were identified and analyzed. All V. Eld. patients (n = 253) were subsequently selected, and their outcomes compared to Eld. patients (n = 327). Mean follow-up was 30.8 ± 2.7 months with 98% clinical follow-up achieved.

All comparative data are expressed as (V. Eld. vs Eld.) unless otherwise specified. All-cause mortality was significantly higher in the V. Eld. group (11.9% vs 6.1%), although this did not translate into a significant difference in cardiac mortality (6.3% vs 3.7%) or major adverse cardiac and cerebrovascular events (16.2% vs 12.5%). The composite incidence of myocardial infarction (MI), stroke, definite/probable stent thrombosis, and TIMI major bleed was 4.7%, 1.4% 1.9%, and 6.4%, respectively with no significant difference between both cohorts.

This study demonstrates an acceptable occurrence of MI, death, repeat intervention, and stent thrombosis in a high-risk group of V. Eld. patients with de novo lesions. Age alone in the absence of other non-cardiac factors should not prohibit a patient from access to PCI.
