[Hemodynamics and its control in patients with thyrotoxicosis and in healthy persons according to the data of anapriline and graded exercise tests].
The study was undertaken to examine effects of anapriline on bicycle ergometric and echocardiographic parameters and catecholamine excretion in 17 patients with thyrotoxicosis and 21 healthy subjects. A single dose of anapriline contributed to transition of hyperkinetic central hemodynamics to eukinetic one and a more saving regimen of heart performance at rest and submaximal exercise levels in the healthy subjects. In contrast, the patients maintained hyperkinetic hemodynamics and had a high energy demand during exercise and showed a reduction in left ventricular systolic and diastolic function and a significant decrease in catecholamine excretion. Disintegration of regulatory mechanisms in thyrotoxicosis was found to be due to the function interrelationship between thyroid hormones and catecholamines.
