What is the rate of clinical plaque progression requiring nontarget lesion PCI in patients with incidental asymptomatic lesions discovered during culprit vessel PCI?
Approximately 6% of patients undergoing PCI experience clinical progression of incidental asymptomatic lesions requiring intervention within 1 year, with risk driven by greater baseline CAD burden.
Approximately 6% of PCI patients will have clinical plaque progression requiring nontarget lesion PCI by 1 year. Greater coronary artery disease burden confers a significantly higher risk for clinical plaque progression.
Glaser et al. (2004) studied this question.
