Determining the association between the type of intervention for ischaemic heart disease and mortality and morbidity in patients with chronic kidney disease

Introduction: Association between chronic kidney disease (CKD) and ischaemic heart disease (IHD) is well known. Clinically, because of the use of intra-arterial contrast, coronary angiograms are sometimes not performed to avoid further deterioration in kidney function amongst CKD patients. Therefore, our aim is to identify whether intervention for non-ST elevation myocardial infarction (NStemi) is associated with increased mortality or further renal deterioration. Method: A retrospective observational cohort study was undertaken involving 144 patients with diagnosis of IHD in the CKD.QLD registry from May 2011 to August 2017, with minimum of 2 years follow-up. Patients were divided into two groups based on whether they obtained an interventional or medical management for NStemi. Results: 59 patients had medical management and 85 patients had intervention for IHD. Patients in the medical management group were observed to be significantly older (median:78vs69years,p<0.05) with worse baseline renal function (median:31vs36ml/min/1.73m3,
