Short and long-term prognosis of chronic kidney disease in patients undergoing primary angioplasty

Abstract

To the Editor, Coronary artery disease due to sustained inflammation and the effects of calcification promoters is the leading cause of morbidity and mortality in patients with chronic kidney disease.1,2 When seen on the optical coherence tomography, the atheromatous plaques of these patients show features of vulnerability.3 The prevalence or kidney disease (KD) in patients with acute coronary syndrome is up to 30% and is an independent predictor of both ischemic and hemorrhagic adverse events.1 However, the evidence available on the prognostic impact of KD in patients with ST-segment elevation acute myocardial infarction treated with a primary angioplasty is scarce.4-8 Our objective was to assess the long-term and in-hospital prognosis (5-year follow-up) of a single-center, retrospective cohort of patients who underwent a primary angioplasty between 2007 and 2014. We assessed the frequency of the composite endpoint of dead, stroke or non-fatal...
