Role of diabetes and insulin use in the risk of stroke and acute myocardial infarction in patients with atrial fibrillation: A Medicare analysis.

ABSTRACT:

Background

Atrial fibrillation (AF) is associated with elevated risk for ischemic stroke and myocardial infarction (MI). The aim of the study is to assess the role of insulin use on the risk of stroke and MI in AF patients with diabetes.

Methods

We identified Medicare beneficiaries with new AF in 2011 to 2013. Primary outcomes were ischemic stroke and MI. Multivariate Cox regression models were used to assess the association between AF and time to stroke and MI. We adjusted for anticoagulant as a time-dependent covariate.

Results

Out of 798,592 AF patients, 53,212 (6.7%) were insulin-requiring diabetics (IRD), 250,214 (31.3%) were non-insulin requiring diabetics (NIRD) and 495,166 (62%) were non-diabetics (ND). IRD had a higher risk of stroke when compared to NIRD (ad
