Vitamin D and Cardiovascular Events in Rheumatoid Arthritis
Association Between Baseline Vitamin D Metabolite Levels and Risk of Cardiovascular Events in Rheumatoid Arthritis Patients. A Cohort Study With Patient-record Evaluated Outcomes.

Description détaillée
Cardiovascular morbidity and mortality is increased in patients with rheumatoid arthritis (RA), and among these patients, the prevalence of hypo-vitaminosis D is high. Low levels of vitamin D have been associated with elevated cardiovascular risk in healthy subjects. The objective of this study is to evaluate the risk of cardiovascular events in patients having low 25OHD-total levels at baseline compared to patients with sufficient levels, in an aggressively treated closed cohort of early-diagnosed RA patients.
The primary outcome will be the proportion of patients with any cardiovascular event, evaluated using systematic journal audits. Logistic regression models will be applied to test the hypothesis that there are more cardiovascular events in patients enrolled with a low level of vitamin D (< 50 nmol/l). Secondarily, Cox regression models, based on survival analysis, will be applied, to determine the extent to which independent variables (including different levels of vitamin D at baseline) predict not only whether a cardiovascular event occur, but also when it will occur.

---|---|---|
Cardiovascular event
Délai: Observed in the time-period from inclusion to October the 10th 2016
|
Events will be recorded using systematic journal audits.
A cardiovascular event will be further subclassified as shown in the secondary outcome measures, but for primary outcome measures; any cardiovascular event, including death, will serve as "an event"

Acute cardiovascular hospitalisation due to Myocardial Ischamia
Délai: Observed in the time-period from inclusion to October the 10th 2016
|
Non-fatal or fatal myocardial infarction, defined by National and International Guidelines (Thygesen et al. 1581-98). Fatal myocardial infarction is defined as primary fatal event within 7 days, documented post mortem by autopsy, or by the definition of myocardial infarction according to European Guidelines (Thygesen et al. 1581-98) Death of myocardial infarction as a consequence of medical examination/procedure/surgery will be classified as procedure related death. Acute Coronary Syndrome (ACS) includes acute ischaemic symptoms with eventual elevation in biomarkers or electrocardiographic changes which does not fulfil the criteria of acute myocardial infarction. Angina Pectoris. Revascularisation procedures (Percutaneous Coronary Intervention (PCI) or Coronary bypass Graft (CABG). |
