Hs-CRP/ALB Levels Are Associated With Poor Long-term Prognosis in Patients With STEMI Undergoing Percutaneous Coronary Intervention.

Abstract

Research has explored the relationship between inflammatory biomarkers and cardiovascular diseases, highlighting the potential prognostic significance of the high-sensitivity C-reactive protein (hs-CRP)/albumin (ALB) ratio. However, it remains unclear whether this ratio is associated with adverse prognosis in patients with ST-segment elevation myocardial infarction (STEMI) undergoing percutaneous coronary intervention (PCI). This retrospective cohort study included 752 STEMI patients undergoing PCI at Tianjin Chest Hospital between January 2017 and December 2018. During a median follow-up of 52 months, 183 cases (24.0%) experienced major adverse cardiovascular events (MACE) events and 75 cases (10.0%) died. Cox regression analysis demonstrated that hs-CRP/ALB was independently associated with MACE as both a continuous (hazard ratio [HR] 1.152, 95% CI 1.097-1.210, P < .001) and categorical variable (HR 1.257, 95% CI 1.084-1.458, P = .027). Similar findings were observed for all-cause mortality (HR 1.119, 95% CI 1.058-1.183, P < .001; HR 2.228, 95% CI 1.009-4.920, P = .032). The receiver operating characteristic (ROC) curve indicated that hs-CRP/ALB levels have predictive capability for overall mortality in patients (the area under the curve [AUC] = 0.68). hs-CRP/ALB levels independently correlate with poor long-term prognosis in STEMI patients with prior PCI.
