A Systematic Review on the Quality of Life Benefits after Percutaneous Coronary Intervention in the Elderly

AIMS: Percutaneous coronary intervention (PCI) is being increasingly performed on elderly patients with acceptable peri-procedural outcomes and long-term survival. We aim to systematically review the health-related quality of life (HRQOL) following PCI in the elderly which is an important measure of procedural success. METHODS: A systematic review of clinical studies before September 2012 was performed to identify HRQOL in the elderly after PCI. Strict inclusion and exclusion criteria were applied. Quality appraisal of each study was also performed using pre-defined criteria. HRQOL results were synthesised through a narrative review with full tabulation of results of all included studies. RESULTS: Elderly patients have significant improvements in cardiovascular well-being. Early HRQOL appears improved from baseline, but recovery in physical health may be slower than in younger patients. HRQOL is comparable to an age-matched general population and younger patients undergoing PCI. Conservative management is not able to offer the same HRQOL benefits. Coronary artery bypass graft surgery may be superior to PCI in the very elderly. Significant heterogeneity and bias exists. Lack of appropriate data precluded meta-analysis. CONCLUSION: HRQOL after PCI in the elderly can improve for at least 1 year across a broad range of health domains, and is comparable to an age-matched general population and younger patients undergoing PCI. Given a limited number of articles and patients included, more prospective studies are needed to better identify the benefits for elderly patients.
