OBJECTIVE: This review analyzes the prevalence of the most important comorbidities associated with atrial fibrillation (AF) in the growing population of patients with Cushing’s syndrome (CS).
MATERIALS AND METHODS: The review is arranged in a way to list important risk factors for AF and the references, which suggest the significant prevalence of these particular risk factors in CS. The search is conducted on PubMed, Science Direct, Springer, Wiley, SAGE, Oxford Press, and Google Scholar. PubMed search for “Cushing’s syndrome atrial fibrillation” on 8/7/2019 revealed 4 papers only. None of them either analyzed or implicated high risk for AF in CS.
RESULTS: Arterial hypertension (AHT) can be found in approximately 80% of adult individuals with endogenous CS and in 20% of patients with exogenous CS. The reported prevalence of diabetes mellitus (DM) is from 13% to 47% in CS patients and the risk for de novo DM is approximately two-fold higher in individuals treated with glucocorticoids. High risk for myocardial infarction (MI) with hazard ratio (HR) 3.7 (95% confidence intervals, CI 2.4-5) in patients with endogenous CS was found. In CS patients the obesity can be detected in up to 41% and overweight in 21-48%. Left ventricular hypertrophy (LVH), pulmonary thromboembolism (PTE), infections, and hypokalemia are also more prevalent in CS as compared to healthy population. All cited comorbidities have been associated with AF. Therefore, clustering of the important factors associated with AF is confirmed repeatedly in CS.
CONCLUSIONS: The prevalence of AF in CS should be studied more precisely, both in a scientific way and at the individual patient’s level.Free PDF Download
