Percutaneous coronary intervention (PCI) is increasingly being performed on elderly patients with acceptable periprocedural outcomes and long-term survival rates. Selecting the appropriate patients for revascularization is more important for elderly people. The aim of this study is to determine the most important independent risk factor that could predict clinical outcomes in elderly patients who undergo PCI.
A total of 1884 consecutive patients who underwent PCI were evaluated. The enrolled patients were divided into 2 groups according to age, namely, younger patients who were aged < 75 years and elderly patients who were aged ≥ 75 years. The study’s primary end point was the occurrence of major adverse cardiac or cerebrovascular events (MACCE) at 1 year.
The 1-year cumulative incidence of MACCE was 4.9%, and it was 3.8% in the younger patient group and 9.9% in the elderly patient group (P < 0.001). Forty-nine patients (2.6%) died during the follow-up period. The 1-year mortality rate was 1.5% (23 patients) for the younger patient group and 7.1% (26 patients) for the elderly patient group (P < 0.001). Previous cerebrovascular disease was significantly correlated with MACCE at 1 year in elderly patients treated with PCI (HR, 3.079; 95% CI, 1.276-7.426, P = 0.012).
Previous cerebrovascular disease is the most important independent predictor of the occurrence of MACCE in elderly patients 1 year after PCI.
