The Association Between High-Sensitivity C-Reactive Protein/Albumin Ratio and Cardiovascular Prognosis in Patients Undergoing Percutaneous Coronary Intervention

Limited studies have focused on the impact of high-sensitivity C-reactive protein (hsCRP) to albumin ratio (CAR) on cardiovascular outcomes in patients undergoing percutaneous coronary intervention (PCI). Hence, the present study evaluates the association between CAR and cardiovascular outcomes in patients undergoing drug-eluting stent (DES) implantation. We consecutively enrolled 9375 CHD patients undergoing DES implantation. All patients were divided into 3 groups according to their CAR: tertile 1 (CAR ≤.02, n=3125), tertile 2 (.02<CAR≤.06, n = 3125), and tertile 3 (CAR >.06, n = 3125). The primary endpoint was major adverse cardiovascular and cerebrovascular events (MACCE). Kaplan-Meier analysis indicated that the incidences of MACCE and MI increased with high tertiles of the CAR (MACCE: 8.7 vs 10.5 vs 12.3%, log-rank P < .001; MI: 3.3 vs 4.0 vs 4.7%, long-rank P = .015). Cox regression analysis suggested that CAR was an independent risk factors for MACCE (HR per standard deviation (SD) increase: 1.07, 95% CI, 1.01–1.14, P = .024), and MI (HR per SD increase: 1.11, 95% CI, 1.01–1.22, P = .028). In conclusion, the CAR is an independent predictor of MACCE and MI in CHD patients.
