Abstract
The incidence of arrhythmias may be increased in acromegaly but the pathophysiologic mechanisms involved are still unclear and it has never been correlated with structural heart changes analyzed by the goldstandard method cardiac magnetic resonance CMRThirtysix patients were studied at baseline and 28 were reevaluated after 1 year of SA treatment There were 13 females and median age was 48 years 20–73 years Nine patients 32 were controlled after treatment No sustained arrhythmias were reported in the 24h Holter No arrhythmiarelated symptoms were observed Only two patients presented left ventricular hypertrophy and three patients presented fibrosis at baseline There was no correlation of the left ventricular mass with the number of episodes of arrhythmias and they were not more prevalent in the patients presenting cardiac fibrosisWe found no sustained arrhythmias and a lack of arrhythmiarelated symptoms at baseline and after 1 year of SA treatment in a contemporary cohort of acromegaly patients that also present a low frequency of structural heart changes indicating that these patients may have a lower frequency of heart disease than previously reported
