Key result
Repeat revascularization after initial PCI occurred in 16.9% of elderly patients and independently increased 1-year medical care costs by $19,074 (95% CI, 18,440-19,707; P<0.001).

Repeat revascularization after PCI was associated with higher costs in elderly patients; leaves open whether restenosis prevention improves value.
Cohort (n=9,868)
Yes

In an unselected elderly population undergoing initial PCI, repeat revascularization is common and significantly increases 1-year healthcare costs, highlighting the economic burden of restenosis.
Clark et al. (2004) conducted a cohort in Initial percutaneous coronary intervention (PCI) (n=9,868). Repeat revascularization after initial PCI vs. No repeat revascularization was evaluated on 1-year medical care costs (MD 19074 dollars, 95% CI 18440-19707, p=<0.001). Repeat revascularization after initial PCI occurred in 16.9% of elderly patients and independently increased 1-year medical care costs by $19,074 (95% CI, 18,440-19,707; P<0.001).
