Atrial Fibrillation and Its Association with Endocrine Disorders

Atrial Fibrillation (AF) is the most common arrhythmia affecting millions of people and the number is rising, it is therefore important to understand the risk factors causing AF. Risk factors such as hypertension, heart failure, coronary heart disease, and type 2 diabetes mellitus increase the risk of AF, however, the underlying etiology in a majority of patients remains elusive. Many of the endocrine disorders have been implicated in causing AF and an in depth knowledge of these disorders helps in early diagnosis and treatment. Due to the high prevalence of AF and its complications, it is therefore important to recognize these risk factors and have a low threshold for suspicion while other common causes are being excluded. In this review we summarize the issues related to AF and endocrine disorders. A better understanding of the relationship may lead to the development of the primary preventive strategies, fostering a more preventive and predictive approach that may result in decreased incidence of AF and its associated complications and provide personalized treatment options. For this review we carried out a search of Pubmed, the words or combination of words we used for our search include Endocrine disorders, metabolic disorders, Dyslipidemia, Diabetes mellitus type 2, Vitamin D, Hyperthyroidism, Primary aldosteronism, Pheochromocytoma, Obesity, Hypercalcemia, Hypogonadism, Medications, and Atrial fibrillation. We also retrieved articles from the references of retrieved articles.
