Abstract:
Introduction: Prognosis in high-bleeding risk (HBR) patients after percutaneous coronary intervention (PCI) is largely dependent on risk of ischemic/bleeding events. Inflammation is known to increase the ischemic risk following PCI in the general population, yet its impact on HBR patients remains unknown. Hypothesis: We assessed the hypothesis that inflammation, as reflected by elevated high-sensitivity C - reactive protein (hsCRP), increases the risk of ischemic and bleeding events in HBR patients undergoing PCI. Methods: We included patients who underwent PCI at a tertiary care center between 2014 and 2017. Patients were classified as HBR if they met ≥1 major or ≥2 minor criteria according to the Academic Research Consortium (ARC)-HBR consensus. Patients were then stratified into high (≥3 mg/l) and low ( 〈 3 mg/ml) baseline hsCRP level; those presenting with myocardial infarction (MI) or hsCRP 〉 10 mg/l were excluded. The main outcomes of interest were major adverse cardiac events (MACE) (composite of all-cause death, MI, and target vessel revascularization) and bleeding events. Results: Out of 7,186 patients included, 3,403 (42.3%) fulfilled the ARC-HBR definition of whom 1,046 (34.4%) had high hsCRP. These patients were frequently female, younger, and had more cardiovascular risk factors (diabetes, kidney disease, and peripheral artery disease) yet similar angiographic features (multivessel disease, syntax score, and lesion length) than those with low hsCRP. Although risk of MACE at 1 year was similar in HBR patients with either high or low hsCRP, mortality risk was significantly higher in the former group ( Figure 1 ). In addition, HBR patients with high hsCRP were more likely to have periprocedural bleeding (OR 1.72, 95% CI [1.14-2.58], p=0.01) but similar risk of 1-year major bleeding as HBR patients with low hsCRP ( Figure 1 ). Conclusion: In conclusion, inflammation is associated with periprocedural bleeding and 1-year mortality in HBR patients undergoing PCI.
