Abstract:
Background
We aimed to identify the association of degree of renal failure in chronic kidney disease patients who underwent percutaneous coronary intervention (PCI) at our center with 5-year major adverse cardiac events (MACE).
Methods
In this cohort study, we enrolled all patients who underwent primary or elective PCI and completed their 5-year followup unless they developed events related to study end-points. Demographic, angiographic and clinical data of the participants were retrieved from our databank. Glomerular filtration rate (GFR) was calculated based on the Cockcroft-Gault equation for men and women, separately. Accordingly, our patients were classified into three groups: GFR ≥ 60, GFR < 60 and ≥30 and GFR < 30 mL/ min. Then, the demographic and clinical data, as well as the frequency of MACE and its elements, were compared between the study groups.
Results
We included the data for 5,510 patients. MACE occurred in 891 (16.1%) of the patients. A total of 632 cases (16.7%) occurred in patients with GFR > 60 while 224 cases (18.8%) and 35 events (43.7%) occurred in patients with 30 ≤ GFR < 60 and GFR < 30 mL/min, respectively. So, GFR < 30 mL/min was significant predictor for MACE (hazard ratio [HR] = 3.74, 95% CI: 2.64–5.28; P < 0.001). The prediction effect of GFR < 30 remained significant after adjustment for the confounding variables (HR = 3.43, 95% CI: 2.38–4.94; P < 0.001).
Conclusion
GFR <30 mL/min was a strong predictor for 5-year MACE. Moreover, in patients with GFR > 30 mL/min, PCI is a more applicable approachKeywords:
