Blockade of the renin-angiotensin-aldosterone system (RAAS) with angiotensin-converting enzyme inhibitors (ACEIs) and angiotensin receptor blockers (ARB) has been shown to decrease incident atrial fibrillation (AF). Vitamin D deficiency has been implicated but associations between vitamin D and AF are inconsistent. However, vitamin D deficiency results in renin and angiotensin upregulation. This study seeks to determine the relation between vitamin D deficiency and incident AF and characterize this relation in the setting of RAAS inhibition.
