Core Tip
Core Tip: This study evaluates how frailty affects the outcomes of percutaneous coronary intervention (PCI) in patients aged ≥ 75 years with non-ST-elevation myocardial infarction. Using the Hospital Frailty Risk Score, we found that PCI is associated with a reduction in in-hospital mortality across all frailty categories. However, the benefits of PCI decrease as frailty increases, while complications and healthcare utilization significantly rise. These findings emphasize the need for individualized treatment strategies. While frailty should not prevent PCI, it should be considered in shared decision-making to balance the survival benefits against the procedural risks and resource demands in this high-risk population.
