Abstract

Abstract: Aims: Chronic kidney disease (CKD) is associated with an increased risk of cardiovascular disease (CVD). We examined the characteristics, management and outcomes of patients with CKD in the All New Zealand Acute Coronary Syndrome Quality Improvement (ANZACS‐QI) national registry. Methods: The cohort comprised New Zealand (NZ) patients with an acute coronary syndrome undergoing coronary angiography between January 2013 and December 2016. Patients were categorized according to their stage of CKD. Outcomes included all‐cause and cause‐specific mortality and hospitalization with myocardial infarction (MI), stroke and major bleeding. Results: Of the 20 604 patients, 20.3% had normal renal function, with 53.3%, 23.3%, 1.7% and 1.4% having CKD stages 2, 3, 4 and 5 CKD, respectively. Patients with severe CKD were more likely to be Māori or Pacific and live in an area with greater socioeconomic deprivation. Death, recurrent MI or stroke, and major bleeding all increased incrementally with each worsening stage of CKD severity. Compared with those with normal renal function, patients with stage 5 CKD had a much higher all‐cause (hazard ratio [HR] 16.41, 95% CI 13.06‐20.61), cardiovascular (HR 16.38, 95% CI 12.17‐22.04) and non‐cardiovascular mortality (HR 13.66 9, 95% CI.56‐19.51). In addition, patients with stage 5 CKD were at a higher risk of recurrent MI or stroke (HR 4.73, 95% CI 3.86‐5.80) and bleeding (HR 5.84, 95% CI 4.39‐7.76). Conclusion: CKD was associated with increased mortality and a high incidence of morbidity in patients undergoing coronary angiography in New Zealand. Initiatives to understand and improve outcomes in this group of patients are urgently needed. SUMMARY AT A GLANCE: Based on an observational study of 20, 604 public hospital patients suffering from acute coronary syndrome and followed by coronary angiography in New Zealand, the risk of death and recurrent cardiovascular events, as well as bleeding was shown to increase, in a stepwise manner, with worsening CKD stages.
