Novel CHIP score to predict complex PCI outcomes- Dr. Abhimanyu explains the CHIP SCORE

Complex high-risk and indicated percutaneous coronary interventions (CHIP-PCI) is a rapidly growing field that remains somewhat ill-defined with considerable variability among operators. Unlike risk assessment for coronary artery bypass grafting (CABG), which is based on established scoring systems like the STS (Society of Thoracic Surgeons) score or EuroSCORE II models, data on risk stratification for PCI are less robust.

In a recent study published in JACC Cardiovascular Interventions, Protty et al have proposed a new scoring system-the CHIP score based on both patient and procedural characteristics to define and predict outcomes of CHIP-PCI.

This score was found to be associated with increased in-hospital major adverse cardiac and cerebrovascular events (MACCE). An arbitrary cut-off value of 5 has been proposed to define a CHIP case.
