Key result
Patient age did not significantly affect improvements in health-related quality of life 1 year after elective percutaneous coronary intervention, with all age groups achieving significant gains (p=0.01).

Does patient age affect improvements in health-related quality of life at 1 year following elective percutaneous coronary intervention?
p-value: p=0.01
Elective percutaneous coronary intervention provides significant and comparable improvements in health-related quality of life at 1 year across all age groups, suggesting age alone should not deter PCI for symptom relief.
Supports age-independent HRQoL gains after elective PCI; leaves open causal confirmation in randomized trials.
This study was performed to assess the possibility that patient age may independently affect improvements in health-related quality of life following percutaneous coronary intervention. One hundred five patients undergoing elective percutaneous coronary intervention at a single tertiary referral center between January 10, 2001 and January 6, 2002 were enrolled and prospectively evaluated. Health-related quality of life was assessed before and 1 year following percutaneous coronary intervention using Short Form-12 and the Seattle Angina Questionnaire. For the purpose of analysis, patients were divided according to age (younger than 60, 60-70, and older than 70 years). One hundred patients (95%) completed both questionnaires. Baseline characteristics among the age groups were similar in terms of gender, cardiac risk factors, and procedural details. All health-related quality-of-life indices demonstrated improvements with at least four variables in each group achieving a clinically significant increase (>20%). At least eight modalities in each group achieved statistical significance (p=0.01). With the exception of physical functioning, the improvements in health-related quality of life were not significantly different among age groups.

Moore et al. (2006) conducted an observational in Elective percutaneous coronary intervention (n=105). Age vs. Different age groups (<60, 60-70, >70 years) was evaluated on Improvements in health-related quality of life (Short Form-12 and Seattle Angina Questionnaire) (p=0.01). Patient age did not significantly affect improvements in health-related quality of life 1 year after elective percutaneous coronary intervention, with all age groups achieving significant gains (p=0.01).
