Serum uric acid level is a commonly measured biomarker. The association between serum uric acid level and the risk of developing cardiovascular diseases has been observed in some studies, while others showed controversial results. Estimation of this association may help to predict cardiovascular outcomes and may guide new treatment strategies. The hypothesis is that increased serum uric acid level is associated with a range of cardiovascular diseases.
Smaller observational studies suggested that increased serum uric acid level is associated with increased incidence of several cardiovascular diseases. Associations with specific initial presentations of cardiovascular diseases have not been studied in large cohort from the general population, but may be of interest for use in risk prediction or to guide therapeutic strategies. The aim of this study is to estimate associations between serum uric acid level and initial presentation of a range of cardiovascular diseases. The study will use data from the CALIBER dataset of clinically collected electronic health record data from England. Patients enter the study when they have a blood urate measurement recorded in the dataset, and they are followed up until they experience one of the cardiovascular endpoints, death or transfer out of the participating primary care practice. This study is part of the CALIBER (Clinical disease research using linked bespoke studies and electronic records) programme funded from the National Institute for Health Research (NIHR) and Wellcome Trust. The central theme of the CALIBER research is linkage of the Inpatient Hospital Episode Statistics (HES) with primary care (Clinical Practice Research Datalink) and other resources. The overarching aim of CALIBER is to better understand the aetiology and prognosis of specific coronary phenotypes across a range of causal domains, particularly where electronic records provide a contribution beyond traditional studies. CALIBER has received both Ethics approval (ref 09/H0810/16) and ECC approval (ref ECC 2-06(b)/2009 CALIBER dataset).
Study Type
OBSERVATIONAL
Enrollment
180,000
Initial presentation of cardiovascular diseases
First recorded diagnosis of cardiovascular disease during follow-up: Stable angina, unstable angina, myocardial infarction, unheralded coronary heart disease death, heart failure, cardiac arrest/sudden cardiac death, transient ischaemic attack, ischaemic stroke, subarachnoid haemorrhage, intracerebral haemorrhage, peripheral arterial disease, abdominal aortic aneurysm, atrial fibrillation. We will identify the diagnoses using ICD-10 or Read codes in the linked data sources. Definitions for each endpoint are provided on the CALIBER data portal (https://www.caliberresearch.org/portal).
