Haemodynamics of hyperthyroidism: increased cardiac work and findings related to vasodilatation.

ABSTRACT:

Objective

Hyperthyroidism increases cardiovascular morbidity and mortality, but the underlying mechanisms are not fully understood. In this study we compared non-invasive haemodynamics between 20 hyperthyroid patients and 60 euthyroid subjects.

Methods

The measurements were performed median 6 days after the initiation of antithyroid medication when the patients were still hyperthyroid. Three controls matched for age, sex, body mass index, and smoking status were selected for each patient. Recordings were performed during rest and passive head-up tilt using whole-body impedance cardiography, radial pulse wave analysis, and finger blood pressure measurements.

Results

Systolic and diastolic blood pressures in the aorta and radial artery were similar in hyperthyroid and e
