Comparison of Outcomes of Elective Percutaneous Coronary Intervention between Complex and High-Risk Intervention in Indicated Patients (CHIP) versus Non-CHIP

Aims: Complex and high-risk intervention in indicated patients (CHIP) is an emerging concept in the contemporary percutaneous coronary intervention (PCI). CHIP is known to consist three factors, namely, (1) patient factors, (2) complicated heart disease, and (3) complex PCI. However, it remains uncl...

Sumario:Aims: Complex and high-risk intervention in indicated patients (CHIP) is an emerging concept in the contemporary percutaneous coronary intervention (PCI). CHIP is known to consist three factors, namely, (1) patient factors, (2) complicated heart disease, and (3) complex PCI. However, it remains unclear whether additional CHIP factors further increase the incidence of complications in complex PCI. Thus, in this study, we aim to compare the incidence of complications among definite CHIP, possible CHIP, and non-CHIP in terms of complex PCI and to further investigate the association between CHIP and complications. Methods: The primary aim of this study was to determine the major complications in PCI. We included 989 PCI lesions and divided those into definite CHIP (n=140), possible CHIP (n=397), and the non-CHIP groups (n=452). Results: The incidence of major complications was noted to be the highest in the definite CHIP, followed by the possible CHIP, and lowest in the non-CHIP (p=0.001). The multivariate logistic regression analysis using a generalized estimating equation revealed definite CHIP (versus non-CHIP: odds ratio (OR) 2.099, 95% confidence interval (CI) 1.062–4.150,p=0.033) was significantly associated with major complications after controlling for confounding factors. Another multivariate logistic regression analysis revealed immunosuppressive drugs (OR 3.040, 95% CI 1.251–7.386,p=0.014), unstable hemodynamics (OR 5.753, 95% CI 1.217–27.201,p=0.027), and frailty (OR 2.039, 95% CI 1.108–3.751,p=0.022) were significantly associated with major complications among CHIP factors. Conclusions: The incidence of major complications in complex PCI was determined to be the highest in the definite CHIP, followed by the possible CHIP and lowest in the non-CHIP. Thus, more attention should be given to the three components of CHIP to prevent major complications in complex PCI.
