Background: Impact of percutaneous coronary interventions (PCI) on health-related quality of life (HRQOL) is important but under-reported in elderly patients. Objectives: To evaluate long-term health status in elderly patients who underwent PCI. Methods: Consecutive patients who underwent PCI at a university-affiliated hospital from September 2009 to June 2012 were prospectively enrolled with HRQOL assessment at baseline (up to 2 weeks before PCI) and at 6-, 12-, and 36-month follow-up using the EuroQol five-dimensional questionnaire descriptive profile and visual analogue scale (VAS). Minimally important benefit (MIB) in HRQOL was defined as greater than half an SD improvement in the baseline VAS score. Results: Of 1957 patients, 49.9%, 29.1%, and 21.0% were aged younger than 65 years, 65 to 74 years, and 75 years and older, respectively. Mean VAS scores at baseline (50.1 ± 20.5 vs. 51.6 ± 20.5 vs. 52.6 ± 21.8; P = 0.09) and at 36 months (72.9 ± 14.0 vs. 72.8 ± 16.1 vs. 72.0 ± 14.8; P = 0.77) were similar between the three age groups, respectively. MIB at 36 months was observed in 65.7%, 61.9%, and 61.2% of patients in each age group, respectively. Proportion of patients aged 75 years and older reporting problems in pain/discomfort and self-care reduced from 91.2% and 24.8% at baseline to 41.4% and 10.1% at 36 months, respectively (both P < 0.01). Independent predictors of MIB in HRQOL at 36 months in patients 75 years and older included poor baseline HRQOL, MIB at 6 months, and presentation with myocardial infarction (all P < 0.01). Conclusions: Elderly patients experienced sustained long-term improvement in quality of life comparable with younger patients after PCI. Our findings suggest that age per se should not deter against revascularization because of sustained benefit in HRQOL.
