Disproportionate hypertrophy of the interventricular septum and its regression in Cushing's syndrome. Report of three cases.
Three patients of Cushing's syndrome with severe disproportionate hypertrophy of the interventricular septum are reported. All three underwent adrenalectomy and the diagnosis of Cushing's syndrome was confirmed by the presence of adrenal adenoma. All three showed hypertension before the adrenalectomy and two remained hypertensive following adrenalectomy. Before the operations the electrocardiograms revealed inverted T waves in broad leads, and mechanocardiogram systolic and diastolic dysfunction. After the adrenalectomies, abnormal findings on electrocardiograms were normalized and septal hypertrophy was completely regressed. It appears that not only high aortic pressure but also excessive plasma cortisol may be an etiologic factor of the left ventricular hypertrophy in Cushing's syndrome.
