This study comprises 81 thyrotoxic patients with onset after the age of 60. In elderly persons, toxic multinodular goiter is the most common cause (68%) of hyperthyroidism, followed by solitary thyroid nodules (16%) and Graves' disease (16%). Cardiovascular disorders (cardiac failure, arrythmias etc.) constitute the first and often the only symptom in 62% of the cases. The other forms of appearance are both various and deceptive: depression, slight fever, asthenia or nausea. Separate analysis of the three forms of hyperthyroidism did not reveal clinical, biological or therapeutic differences between them, except an inferior rate of captation for the toxic nodules. Isolated measurement of T3 or T4 is often insufficient to confirm the diagnosis because either of these hormones may appear at a normal rate. In three cases only the free thyroxin index was pathological on first determination. The authors have established that the autonomous nodules are larger and more active after, rather than before, 60 years of age, and have attempted to define their morphological identity. The results of the treatment are analyzed and preference is expressed for radioactive iodine in every form of hyperthyroidism.

A case of peripartum cardiac failure is reported in a 20-year-old gravida 3, para 3 black female. The patient was 6 weeks postpartum. Graves' disease had been diagnosed in the first trimester of her pregnancy. The patient presented to the emergency department with complaints of fever, abdominal pain, shortness of breath, and chest pain. Physical examination revealed signs of congestive heart failure and anasarca. Chest x-ray revealed bilateral pleural effusions, and an abdominal series was consistent with ascites. Bedside electrocardiogram revealed pan-hypokinesis of all four cardiac chambers. The authors believe that this is the first case reported in the literature of peripartum cardiac failure occurring in a patient with Graves' disease.

A case of open heart surgery of Basedow's disease was presented. A 46-year-old female was admitted for mitral regurgitation with heart failure. She suffered from Basedow's disease ten years ago, and was treated with MMI. With this treatment, her thyroid function became normal and did well over the last four years. When open heart surgery (MVR) was performed, examination of her thyroid gland revealed mild hypothyroidism, and the operation could be performed without any thyroidal trouble. We conclude, in case of heart disease with Basedow's disease, the operation can be performed without any thyroidal trouble if the thyroid function is controlled well to euthyroid for a long term. Euthyroid condition lasted 4 years in this case.

A middle-aged man with Graves' disease presented with heart failure in sinus rhythm which preceded the more typical manifestations of the disease by some months. Once suspected, the diagnosis was supported by measurement of systolic time intervals, enabling the instigation of treatment in advance of biochemical confirmation.

The authors describe the clinical characteristics and response to therapy of seven patients with hyperthyroidism, dilated cardiomyopathy, and low-output cardiac failure. All patients (4 women and 3 men, age 47 +/- 4 years, mean +/- standard error of the mean) were admitted with the primary diagnosis of congestive heart failure. The cause of hyperthyroidism was Graves' disease in six patients, and toxic multinodular goiter in one. On admission, the mean serum T4 was 21 +/- 1 microgram/dL and mean serum T3:411 +/- 77 ng/mL, and serum thyroid-stimulating hormone was suppressed ( < 0.03 microU/mL) in all patients. Two-dimensional echocardiogram showed biventricular or four chamber dilatation and impaired left ventricular performance. Therapy of heart failure and hyperthyroidism resulted in rapid clinical improvement. During follow-up (5 months to 9 years), left ventricular ejection fraction improved from a mean of 28% to a mean ejection fraction of 55% (P < 0.01). Resolution of dilated cardiomyopathy with normalization of systolic function was achieved in five patients, and improvement from severe to mild left ventricular dysfunction was observed in two patients. We conclude that some patients with hyperthyroidism may have a reversible form of dilated cardiomyopathy and "low-output failure." Assessment of thyroid hormone status in patients with heart failure might permit the identification of patients with dilated cardiomyopathy and thyrotoxicosis who are likely to have reversible cardia dysfunction.

Graves' disease, which is an organ-specific autoimmune disorder, is the most frequent cause of thyrotoxicosis. Females are more often affected than males. The clinical pattern varies, however, and nearly every organ system may be involved. This case study describes a formerly healthy young woman with Graves' disease who was admitted to the hospital with cardiac failure, convulsions and generalized lymphoid hyperplasia. A reversible thyrotoxic cardiomyopathia combined with hyperdynamic circulation may result in cardiac failure even in younger patients, and the cardiac function normalizes in the euthyroid state. Seizures may occur in association with hyperthyroidism. High doses of propranolol may precipitate the condition by lowering the threshold for seizures.

A patient with primary biliary cirrhosis had a dramatic deterioration in liver function with jaundice over 2 months as a result of development of Graves' disease. Clinical examination and radiological and cardiovascular investigations excluded heart failure and biliary obstruction as the cause of this deterioration. The patient's jaundice entirely reversed with treatment of hyperthyroidism, with bilirubin levels decreasing from 244 to 16 mumol/L (14.35 to 0.94 mg/dL). Deterioration in liver function in a patient with primary biliary cirrhosis as a result of hyperthyroidism has not previously been described.

We report a rare case of Basedow's disease associated with high output heart failure and angina pectoris over the age of 80 years. An 85-year-old woman was admitted with palpitation, finger tremor, hyperidrosis and weight loss. Basedow's disease was diagnosed by physical (diffuse goiter) and laboratory (free T3 19.4 pg/ml, free T4 > 8.0 ng/dl, TSH < 0.1 microU/ml, TRAb positive, 123I uptake high) findings and was treated with methimazole. Chest oppression and dyspnea on exertion with negative T wave, cardiomegaly and pulmonary congestion appeared after methimazole. Cardiac catheterization showed a high cardiac output (CI 5.01/min/m2, PCW 26 mmHg, PA 57/26 mmHg, RA 15 mmHg) and a significant coronary stenosis (LAD [symbol: see text] 99%). High output heart failure and angina pectoris responded to treatment. They subsequently worsened, because she stopped taking methimazole for a month and serum levels of thyroid hormones increased again. After retreatment with methimazole, serum levels of thyroid hormones decreased to within normal limits, and high output heart failure and angina pectoris also improved.

Cardiovascular changes associated with Graves' disease are generally considered to be secondary to the increased levels of thyroid hormone. We describe a case of Graves' disease in a 25-year-old man, who developed cardiomyopathy with severe heart failure. Pathological examination of the myocardial biopsies showed fibroblast infiltration and degenerative changes. After the cardiomyopathy subsided the patient developed a goitre and signs of hyperthyroidism, followed by Graves' ophthalmopathy, which was treated successfully with a combination of high-dose corticosteroids and orbital radiotherapy. These findings suggested a common pathogenesis for the cardiomyopathy and ophthalmopathy, and prompted us to investigate the expression of TSH receptor (TSH-R) in human heart. TSH-R mRNA was identified in human heart using the reverse transcriptasepolymerase chain reaction (RT-PCR) and DNA sequencing. Taken together, these data suggest that autoimmunity against the TSH-R might contribute to both the cardiomyopathy and ophthalmopathy in similar cases of Graves' disease.

Systolic heart failure because of hyperthyroidism in patients without preexisting heart disease is not common. Thyrotoxic systolic heart failure is rarely diagnosed during life. Reports about thyrotoxicosis-related systolic heart failure have been diagnosed postmortem. However, antemortem diagnosis of this fatal disease has important clinical implications because if detected early, thyrotoxicosis-related systolic heart failure is reversible. Here is a report a patient with Graves' disease, systolic heart failure, and deep jaundice, which resolved after the treatment of antithyroid drugs.
