| pubmed-article:582500 | pubmed:abstractText | An echocardiographic study of nine patients with graves' disease before and after treatment demonstrates changes in myocardial contractility predominantly in the posterior wall and, to a lesser extent, in the intraventricular septum. The parameters most significantly changed were: velocity of posterior wall thickening and posterior left ventricular wall relaxation rate. There was not in any of the cases neither evidence of cardiac insufficiency nor a diminution of VCF. All of the modifications regressed rapidly with the euthyroid state. These results affirm the functional character of this disease dismissing the existence of an autonome cardiomyopathy of thyroid etiology. | lld:pubmed |
