Alterations in thyroid function induced by chronic administration of amiodarone.

Thyroid function alterations induced by amiodarone treatment (200-400 mg/day for 5 days/week) were studied in 50 patients with heart disease (age 34-75 years, mean age 55.5 +/- 11.8) for 25.

[Role of M-mode and 2-dimensional (sector-scan) echocardiography in studying postinfarct ventricular kinetic changes].

20 patients with previous myocardial infarction clinically suspected to have large impairment of ventricular wall kinesis were studied to evaluate the contribution of M-mode and two-dimensional echocardiography compared with the cineangiographic study in detecting left ventricular asynergy. Two-dimensional cross-sectional echocardiography yielded a satisfactory overlapping of results with ventriculography as far as left ventricular internal dimension and apical and posterior wall kinesis were concerned. The two-dimensional study proved to be an useful technique to observe the interventricular septum, in all its extension and the lateral wall as well.
